Genitourinary syndrome of menopause

Genitourinary syndrome of menopause or GSM previously known as vaginal atrophy, vulvovaginal atrophy, atrophic vaginitis or urogenital atrophy, is a chronic, progressive vulvovaginal, sexual, and lower urinary tract condition characterized by a collection of symptoms that frequently affects more than 50% of postmenopausal women and 15% of hypoestrogenic premenopausal women where the tissues of the urinary tract (urethra, and bladder) and the female genital tract (labia majora, labia minora, clitoris, vestibule or introitus, vagina) gets drier and thinner from a lack of estrogen and other sex hormones ¹⁾, ²⁾, ³⁾, ⁴⁾, ⁵⁾. During menopause, your body makes less estrogen (95% reduction in estrogen production). Without estrogen, the lining of your vagina can become thinner and less stretchy. Your vaginal canal can also narrow and shorten. Less estrogen also lowers the amount of normal vaginal fluids and changes the acid balance in your vagina. All of these factors make your vaginal tissue more delicate and more likely to become irritated.

Your body can also produce less estrogen during events other than menopause. People who are breastfeeding, receiving treatment for cancer or who have had both ovaries (bilateral oophorectomy) removed, primary ovarian insufficiency, ovarian failure due to radiation or arterial embolization, hypothalamic-pituitary disorders and take anti-estrogen medications such as leuprolide or danazol used commonly for endometriosis, can also experience vaginal atrophy due to lack of estrogen ⁶⁾, ⁷⁾. Also at risk are breast cancer survivors suffering from consequences from treatment such as chemotherapy or aromatase inhibitors ⁸⁾, ⁹⁾, ¹⁰⁾. Aromatase inhibitors lower estrogen levels by stopping an enzyme in fat tissue called aromatase from changing other hormones into estrogen ¹¹⁾. Aromatase inhibitors don’t stop the ovaries from making estrogen. They only lower estrogen levels in women whose ovaries aren’t making estrogen (such as women who have already gone through menopause). Because of this, they are used mainly in women who have gone through menopause already.

In 2014, the new term Genitourinary Syndrome of Menopause (GSM) was introduced by the International Society for the Study of Women’s Sexual Health and the North American Menopause Society ¹²⁾. This term encompasses all of the atrophic symptoms patients may have in the vulvovaginal and bladder-urethral areas from loss of estrogen that occurs with menopause ¹³⁾. Genitourinary syndrome of menopause symptoms can vary between patients; however, common GSM symptoms include sexual symptoms (lack of lubrication, discomfort or pain with sex, and impaired function during sex), genital symptoms (dryness, burning, and irritation of the vulva and vagina) and urinary symptoms (frequent urination, urgency, burning urination, and recurrent urinary tract infections). Genitourinary syndrome of menopause (GSM) signs and symptoms may begin to bother you during the years leading up to menopause, or they may not become a problem until several years into menopause. Although the condition is common, not all menopausal women experience GSM. Regular sexual activity, with or without a partner, can help you maintain healthy vaginal tissues.

Genitourinary syndrome of menopause can be a common issue for all women and can impair your quality of life, your sexual function, and your relationships with partners. Many postmenopausal women experience GSM. Women are often reluctant or embarrassed to discuss or receive treatment for their symptoms. They believe the GSM signs and symptoms are expected and part of the aging process. This not only results in underdiagnosing but also undertreatment of this condition. Reports show that 15% of the female population experiences symptoms of vaginal atrophy before menopause, whereas 40% to 54% of postmenopausal women have symptoms ¹⁴⁾, ¹⁵⁾.

Due to sexual embarrassment and the sensitive nature of discussing symptoms, genitourinary syndrome of menopause is greatly underdiagnosed. Approximately 70% of women with genitourinary syndrome of menopause (GSM) signs and symptoms do not discuss the issue with their doctor ¹⁶⁾. According to Nappi et al ¹⁷⁾, only 54% of menopausal women are willing to discuss their sexual health with a specialist and 33% of patients even refuse to answer questions. Most are even not aware of treatment modalities. Therefore, less than 25% of women with GSM do not receive care, and their doctors do not screen for symptoms of vaginal atrophy ¹⁸⁾.

Clinically, genitourinary syndrome of menopause is manifested by dryness in the vagina, painful sexual intercourse (dyspareunia), vaginal discharge, itching, and pain ¹⁹⁾, ²⁰⁾. Painful sexual intercourse (dyspareunia) leads to a decrease in sex drive and fear of sexual intercourse. As the frequency of coitus diminishes, vaginal lubrication declines further ²¹⁾. Some women may already have narrowing of the vagina or manifestations of vaginismus (involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina), limiting the penetration into the vagina. However, in some women with mild-to-moderate severity, genitourinary syndrome of menopause occurs asymptomatically and verification of diagnosis is possible only with vaginal examination ²²⁾.

The spectrum of genitourinary syndrome of menopause (GSM) signs and symptoms makes long-term treatment essential in many patients, not only for relief of symptoms, but also for the more troublesome problems that may occur, such as light bleeding after intercourse (postcoital bleeding) and recurrent urinary tract infections. This in turn can complicate the process of sexual arousal and achievement of orgasm, therefore leading to sexual dysfunction ²³⁾. But few women seek treatment. Women may be embarrassed to discuss their symptoms with their doctor and may resign themselves to living with these symptoms. Simple, effective treatments for genitourinary syndrome of menopause (GSM) are available ²⁴⁾. Make an appointment with your doctor if you have any unexplained vaginal spotting or bleeding, unusual discharge, burning, or soreness. Also make an appointment to see your doctor if you experience painful intercourse that’s not resolved by using a vaginal moisturizer (K-Y Liquibeads, Replens, Sliquid, others) or water-based lubricant (Astroglide, K-Y Jelly, Sliquid, others).

The diagnosis of genitourinary syndrome of menopause (GSM) is made difficult by the low awareness of women about the pathological manifestations of the postmenopausal period and unwillingness/embarrassment to discuss the symptoms of an intimate character with their doctor. In their study, Nappi and Kokot-Kierepa ²⁵⁾ noted that only 4% of respondents associated their symptoms with the manifestations of menopause. Unfortunately, 75% of patients with the clinical manifestations of genitourinary syndrome of menopause (GSM) do not seek help from gynecologists ²⁶⁾.

Diagnosis of genitourinary syndrome of menopause (GSM) may involve:

• Pelvic exam: In a pelvic exam, your health care provider inserts two gloved fingers inside your vagina. Pressing down on your abdomen at the same time, your doctor can examine your uterus, ovaries and other organs.
• Urine test, which involves collecting and testing your urine, if you have urinary symptoms.
• Vaginal pH test, which involves taking a sample of vaginal fluids or placing a paper indicator strip in your vagina to test its acid balance. Vaginal pH measurement is useful if pH>5 in the absence of any infections or discharges.

A healthcare provider can diagnose vaginal atrophy based on your symptoms and a pelvic exam to look at your vagina and cervix. The diagnosis of genitourinary syndrome of menopause (GSM) is confirmed by vaginal examination and colposcopy ²⁷⁾.

Classic signs of vaginal atrophy during a pelvic exam include:

• A shortened or narrowed vagina.
• Dryness, redness and swelling.
• Loss of stretchiness.
• Whitish discoloration to your vagina.
• Vulvar skin conditions, vulvar lesions and/or vulvar patch redness.
• Minor cuts (lacerations) near your vaginal opening.
• Decrease in size of the labia.

A pale, dry, smooth, shiny, and inflammation changes such as patchy erythema or petechiae or increased visibility of blood vessels are all classical findings of atrophy. There may also be friability, bleeding, and discharge ²⁸⁾.

Laboratory tests such as urinalysis and culture, urine antigen for sexually transmitted infections, and pelvic cultures are usually used to rule out genitourinary infections ²⁹⁾. Measurement of estrogen in the form of serum estradiol is inaccurate, and current assays are not sufficiently sensitive to detect accurately ³⁰⁾. Currently, research is the Maturation Index Test. The lining cells of the vaginal wall are measured with atrophy demonstrating shifting and loss of superficial cells to basal cells.

Treatment of genitourinary syndrome of menopause depends on the severity of the symptoms of the disease and on the preferences and expectations of women.

To treat genitourinary syndrome of menopause, your doctor may first recommend over-the-counter treatment options, including:

• Vaginal moisturizers. Try a vaginal moisturizer (K-Y Liquibeads, Replens, Sliquid, others) to restore some moisture to your vaginal area. You may have to apply the moisturizer every few days. The effects of a moisturizer generally last a bit longer than those of a lubricant.
• Water-based lubricants. These water-based lubricants (Astroglide, K-Y Jelly, Sliquid, others) are applied just before sexual activity and can reduce discomfort during intercourse. Choose products that don’t contain glycerin or warming properties because women who are sensitive to these substances may experience irritation. Avoid petroleum jelly or other petroleum-based products for lubrication if you’re also using condoms, because petroleum can break down latex condoms on contact.
• When choosing lubricants and moisturizers, it is important that the product is similar to vaginal secretion in terms of osmolality, pH, and composition ³¹⁾.
• Vaginal lubricants and moisturizers can be used as needed in combination with other genitourinary syndrome of menopause treatments.
• Allow time to become aroused during intercourse. The vaginal lubrication that results from sexual arousal can help reduce symptoms of dryness or burning.

If those options don’t ease your symptoms, your doctor may recommend:

• Topical estrogen. Vaginal estrogen has the advantage of being effective at lower doses and limiting your overall exposure to estrogen because less reaches your bloodstream. Vaginal estrogen may also provide better direct relief of symptoms than oral estrogen does. Vaginal estrogen therapy comes in a number of forms. Because they all seem to work equally well, you and your doctor can decide which one is best for you.
  • Vaginal estrogen cream (Estrace, Premarin). You insert this cream directly into your vagina with an applicator, usually at bedtime. Typically women use it daily for one to three weeks and then one to three times a week thereafter, but your doctor will let you know how much cream to use and how often to insert it.
  • Vaginal estrogen suppositories (Imvexxy). These low-dose estrogen suppositories are inserted about 2 inches into the vaginal canal daily for weeks. Then, the suppositories only need to be inserted twice a week.
  • Vaginal estrogen ring (Estring, Femring). You or your doctor inserts a soft, flexible ring into the upper part of the vagina. The ring releases a consistent dose of estrogen while in place and needs to be replaced about every three months. Many women like the convenience this offers. A different, higher dose ring is considered a systemic rather than topical treatment.
  • Vaginal estrogen tablet (Vagifem). You use a disposable applicator to place a vaginal estrogen tablet in your vagina. Your doctor will let you know how often to insert the tablet. You might, for instance, use it daily for the first two weeks and then twice a week thereafter.
• Ospemifene (Osphena). Taken daily, this pill can help relieve painful sex symptoms in women with moderate to severe genitourinary syndrome of menopause (GSM). It is not approved in women who’ve had breast cancer or who have a high risk of developing breast cancer.
• Prasterone (Intrarosa). These vaginal inserts deliver the hormone dehydroepiandrosterone (DHEA) directly to the vagina to help ease painful sex. DHEA is a steroid precursor hormone (prohormone) with weak androgenic effects that is converted into male sex hormones (androgens) and/or female sex hormones (estrogens) in peripheral tissues in your body to exert their effects ³²⁾, ³³⁾. Prasterone or DHEA is used nightly for moderate to severe vaginal atrophy.
• Systemic estrogen therapy. If vaginal dryness is associated with other symptoms of menopause, such as moderate or severe hot flashes, your doctor may suggest estrogen pills, patches or gel, or a higher dose estrogen ring. Estrogen taken by mouth enters your entire system. Ask your doctor to explain the risks versus the benefits of oral estrogen, and whether or not you would also need to take another hormone called progestin along with estrogen.
• Vaginal dilators. You may use vaginal dilators as a nonhormonal treatment option. Vaginal dilators may also be used in addition to estrogen therapy. These devices stimulate and stretch the vaginal muscles to reverse narrowing of the vagina. If painful sex is a concern, vaginal dilators may relieve vaginal discomfort by stretching the vagina. They are available without a prescription, but if your symptoms are severe, your doctor may recommend pelvic floor physical therapy and vaginal dilators. Your health care provider or a pelvic physical therapist can teach you how to use vaginal dilators.
• Topical lidocaine. Available as a prescription ointment or gel, topical lidocaine (topical local anesthetic) can be used to lessen discomfort associated with sexual activity. Apply it five to 10 minutes before you begin sexual activity.

If you have a history of breast cancer, tell your doctor and consider these options:

• Nonhormonal treatments. Try moisturizers and lubricants as a first choice.
• Vaginal dilators. Vaginal dilators are a nonhormonal option that can stimulate and stretch the vaginal muscles. This helps to reverse narrowing of the vagina.
• Vaginal estrogen. In consultation with your cancer specialist (oncologist), your doctor might recommend low-dose vaginal estrogen if nonhormonal treatments don’t help your symptoms. However, there’s some concern that vaginal estrogen might increase your risk of the cancer coming back, especially if your breast cancer was hormonally sensitive.
• Systemic estrogen therapy. Systemic estrogen treatment generally isn’t recommended, especially if your breast cancer was hormonally sensitive.

What’s the difference between genitourinary syndrome of menopause and a yeast infection?

Both genitourinary syndrome of menopause and yeast infections can have symptoms of dryness, itching, redness and pain. However, lack of estrogen causes vaginal atrophy while a fungal infection causes a vaginal yeast infection. Consult with your doctor regarding symptoms so that, together, you can determine what condition you have.

Genitourinary syndrome of menopause cause

Genitourinary syndrome of menopause is caused by a decrease in estrogen production. Vaginal atrophy is most commonly caused by a decreasing or lower estrogen state. As production and amount of total body estrogen decreases, secretions diminish, and the genitourinary tissues become atrophic, causing the many symptoms associated with genitourinary syndrome of menopause. There are receptors in the vagina, vulva, urethra, and trigone of the bladder that respond to estrogen stimulation to maintain normal blood flow, tissue thickness, tissue folding, tissue elasticity, and keeps the epithelial surfaces moist ³⁵⁾. This healthy tissue is rich in glycogen, which the normal flora Lactobacilli convert to lactic acid. This creates an acidic environment with a pH of 3.5 to 5.0, which the lactobacilli continue to thrive and protect from vaginal and urinary tract infections. Concurrently, sexual activities promote epithelial turnover and elevated vaginal lubrication.

Less estrogen makes your vaginal tissues thinner, drier, its barrier function is lost, the vaginal folding decreases, the elasticity of the tissues decreases, and more fragile and the secretory activity of the Bartholin glands decreases, which lead to traumatization of the vaginal mucosa and painful sensations ³⁶⁾, ³⁷⁾, ³⁸⁾. In addition, under conditions of estrogen deficiency, the balance of the vaginal microbiota is disrupted, the pathogenic gram-negative fecal flora and other bacteria prevail in its composition, and the vagina develops a less acidic pH, that is, from 5.5 to 6.8 ³⁹⁾, ⁴⁰⁾. In studies by Brotman et al ⁴¹⁾, a correlation between the nature of the vaginal microbiota, the low Lactobacillus content, and the development of vulvovaginal atrophy was noticed. The data obtained by the authors demonstrate differences in the vaginal microbiota of pre-, peri-, and postmenopausal women. In the proposed hypothesis, the predominance of anaerobic flora in the vaginal environment plays a role in the development of vulvovaginal atrophy symptoms ⁴²⁾.

A drop in estrogen levels may occur:

• After menopause
• During the years leading up to menopause (perimenopause)
• After surgical removal of both ovaries (surgical menopause)
• During breast-feeding (lactation)
• While taking medications that can affect estrogen levels, such as some birth control pills
• After pelvic radiation therapy for cancer
• After chemotherapy for cancer
• As a side effect of breast cancer hormonal treatment

Genitourinary syndrome of menopause (GSM) also occurs in other low-estrogen states, such as postpartum, during breastfeeding (lactation), women who have surgical removal of both ovaries (bilateral oophorectomy), primary ovarian insufficiency, ovarian failure due to radiation or arterial embolization, hypothalamic-pituitary disorders and take anti-estrogen medications such as leuprolide or danazol used commonly for endometriosis ⁴³⁾, ⁴⁴⁾, ⁴⁵⁾, ⁴⁶⁾. Also at risk are breast cancer survivors suffering from consequences from treatment such as chemotherapy or aromatase inhibitors ⁴⁷⁾, ⁴⁸⁾, ⁴⁹⁾.

Risk factors for genitourinary syndrome of menopause

Certain factors may contribute to genitourinary syndrome of menopause, such as:

• Smoking. Cigarette smoking affects your blood circulation, and may lessen the flow of blood and oxygen to the vagina and other nearby areas. Smoking also reduces the effects of naturally occurring estrogens in your body.
• No vaginal births. Researchers have observed that women who have never given birth vaginally are more likely to develop GSM symptoms than women who have had vaginal deliveries.
• No sexual activity. Sexual activity, with or without a partner, increases blood flow and makes your vaginal tissues more elastic. People who have penetrative sexual activity less often — with or without a partner or partners — may also have a higher risk of moderate to severe vaginal atrophy. Studies show that people who have sex more often tend to have milder cases of atrophy than those who stop having sex. This is because sexual stimulation increases blood flow to your vagina and makes your vaginal tissue more elastic.
• Decreased ovarian functioning due to chemotherapy or radiation therapy.
• Medications that contain antiestrogen properties including tamoxifen, medroxyprogesterone and nafarelin.
• Oophorectomy (removal of your ovaries).
• Some birth control pills.
• Immune disorders.
• Breastfeeding.

Genitourinary syndrome of menopause pathophysiology

Vaginal atrophy occurs in conditions causing a diminished estrogen state. Estrogen typically stimulates exfoliation of vaginal epithelial cells, causing increased levels of glycogen in which vaginal flora lactobacilli convert into lactic acid. This process allows for the replacement of older vaginal epithelium, keeping the typical acidic pH of the vaginal canal. As estrogen levels decrease, this process is hindered, and the vaginal epithelium becomes atrophic with diminished secretions and a less acidic environment (pH >5) ⁵⁰⁾, ⁵¹⁾. This, in turn, increases the risk of vaginal and urinary tract infections.

Pathophysiology of genitourinary syndrome of menopause ⁵²⁾:

• Estrogen deficiency
• Loss of labial and vulval thickness
• Decreased collagen, elasticity, and blood flow
• Reduced vaginal discharge
• Reduced pubic hair, subcutaneous fat of labia majora
• Reduced labia minora and hymenal remnants
• Decreased vaginal cells glucogen => change vaginal microbiome => increased pH
• Decreased pelvic floor strength and control
• Dry and thin epithelium
• Short and narrow vagina
• Prolapse (vaginal vault, pelvic organs, urethral)
• Decreased bladder capacity and sensation
• Vaginal hypersensitivity or decreased feeling

Genitourinary syndrome of menopause prevention

Losing estrogen is part of your body’s natural aging process. However, there are ways to keep vaginal atrophy from getting worse. Avoid vaginal irritants such as perfumes, dye, shampoo, detergents and douching.

Regular sexual activity, either with or without a partner, may help prevent genitourinary syndrome of menopause. Sexual activity increases blood flow to your vagina, which helps keep vaginal tissues healthy.

Genitourinary syndrome of menopause signs and symptoms

The tissue that lines the wall of your vagina becomes thin, dry and inflamed when you have vaginal atrophy. Often, the first sign is less lubrication (vaginal dryness), which you may notice during sex. Other signs and symptoms of genitourinary syndrome of menopause may include ⁵³⁾, ⁵⁴⁾:

• Genital signs and symptoms
  • Vaginal burning
    Vaginal discharge
  • Genital itching or vulvar itching (itching around your external genitals)
  • Irritation/burning/itching
  • Leukorrhea
  • Thinning/graying pubic hair
  • Vaginal/pelvic pain and pressure
  • Shortening and tightening of the vaginal canal
  • Vaginal vault prolapse
• Sexual symptoms
  • Discomfort with intercourse (dyspareunia)
  • Decreased vaginal lubrication during sexual activity
  • Light bleeding after intercourse (post-coital bleeding)
  • Decreased arousal, orgasm, desire
  • Loss of libido, arousal
  • Dysorgasmia
• Urinary signs and symptoms
  • Burning with urination (dysuria)
  • Urgency with urination
  • Frequent urination
  • Blood in your urine (hematuria)
  • Urinary incontinence
  • Stress/urgency incontinence
  • Recurrent urinary tract infections (UTIs)
  • Urethral prolapse
  • Ischemia of vesical trigone

Urinary symptoms of GSM may include frequency, dysuria, and increased risk for urinary tract infections ⁵⁵⁾. For some women, symptoms can be severe enough to preclude penetrative sexual activity and to cause discomfort even with sitting or wiping. In women taking aromatase inhibitors, symptoms are more common and may be particularly severe ⁵⁶⁾.

In a large cohort surveys in western populations, 45-63% of postmenopausal women experienced vulvovaginal symptoms, most commonly vaginal dryness ⁵⁷⁾. In a survey on 1578 women with vaginal discomfort, 83% had vaginal dryness ⁵⁸⁾. Similarly, the frequency of vaginal dryness in Iranian menopause women has reported 41.1% and it is one of the most three frequent symptoms ⁵⁹⁾. In the postmenopausal survivors of breast cancer, 70% are affected by vaginal atrophic symptoms ⁶⁰⁾.

Genitourinary syndrome of menopause complications

If not identified, and treated early, genitourinary syndrome of menopause will cause recurrent genitourinary infections and much vaginal/pelvic discomfort and pain.

Genitourinary syndrome of menopause increases your risk of:

• Vaginal infections. Changes in the acid balance of your vagina make vaginal infections more likely.
• Urinary problems. Urinary changes associated with GSM can contribute to urinary problems. You might experience increased frequency or urgency of urination or burning with urination. Some women experience more urinary tract infections or urine leakage (incontinence).

Genitourinary syndrome of menopause diagnosis

Genitourinary syndrome of menopause is a clinical diagnosis, and laboratory testing is usually unnecessary ⁶¹⁾, ⁶²⁾, ⁶³⁾. A healthcare provider can diagnose vaginal atrophy based on your symptoms and a pelvic exam to look at your vagina and cervix. Although some women with mild GSM remain asymptomatic, many women report symptoms such as vaginal dryness, burning, irritation, decreased lubrication with sexual activity, and painful sex (dyspareunia) with resultant sexual dysfunction ⁶⁴⁾. Changes on examination include scant pubic hair, loss of the labial fat pad, thinning and resorption of the labia minora, narrowing of the introitus, and increased vaginal pH ⁶⁵⁾. Internal examination findings include reduced vaginal caliber; smooth, shiny, pale mucosa with loss of folds; and a cervix flush with the vaginal vault. With inflammation, the vagina may appear erythematous, develop petechiae or increased visibility of blood vessels and bleed easily ⁶⁶⁾. There may also be friability, bleeding, and discharge ⁶⁷⁾.

Diagnosis of genitourinary syndrome of menopause (GSM) may involve:

• Pelvic exam: In a pelvic exam, your health care provider inserts two gloved fingers inside your vagina. Pressing down on your abdomen at the same time, your doctor can examine your uterus, ovaries and other organs. A pelvic examination can be helpful to exclude other vulvar and vaginal conditions that may present with symptoms similar to those of GSM, including irritant, infectious, or inflammatory vaginitis; dermatoses; and neoplasia ⁶⁸⁾.
• Urine test, which involves collecting and testing your urine, if you have urinary symptoms.
• Vaginal pH test, which involves taking a sample of vaginal fluids or placing a paper indicator strip in your vagina to test its acid balance. Vaginal pH measurement is useful if pH>5 in the absence of any infections or discharges.

Laboratory tests such as urinalysis and culture, urine antigen for sexually transmitted infections, and pelvic cultures are usually used to rule out genitourinary infections ⁶⁹⁾. Measurement of estrogen in the form of serum estradiol is inaccurate, and current assays are not sufficiently sensitive to detect accurately ⁷⁰⁾. Currently, research is the Maturation Index Test. The lining cells of the vaginal wall are measured with atrophy demonstrating shifting and loss of superficial cells to basal cells.

Genitourinary syndrome of menopause differential diagnosis

Differential diagnoses must exclude the presence of vulvovaginitis, including candidiasis, bacterial vaginosis, trichomoniasis. Sexually transmitted infections, such as gonorrhea and chlamydia. Dermatologic conditions including lichen planus, lichen sclerosis, or inflammation secondary to an irritant. Symptoms and signs may also mimic urinary tract infections or malignancy ⁷¹⁾. Genitourinary syndrome of menopause differential diagnosis is summarized in Table 1. Although these differential diagnoses must be ruled out, their presence does not exclude the diagnosis, and simply may be recurring symptoms/infections secondary to ongoing vaginal atrophy.

Table 1. Genitourinary syndrome of menopause differential diagnosis

Treatment of genitourinary syndrome of menopause

Genitourinary syndrome of menopause has a few different treatment modalities. It can be classified into non-hormonal and hormonal options.

Non-hormonal treatment with vaginal moisturizers and lubricants is considered first-line. Lubricants provide short-term relief for patients and are typically used for vaginal dryness during intercourse, while moisturizers have a longer-lasting effect and may be used daily to every 2-3 days per week. Patients are also encouraged to continue safe, regular sexual activity. The use of moisturizers, lubricants, and regular safe sexual activities helps in maintaining the health and integrity of the vaginal epithelium and flora.

As the environment of the vagina is altered with the progression of vaginal atrophy, the pH and osmolality of the moisturizer or lubricant are also of importance. Your doctor should be prescribing topical vaginal moisturizers and lubricants which are closest to the physiological conditions of the your natural vaginal environment. This not only assists in symptomatic relief but may also decrease the incidence of promoting vaginal infections ⁷³⁾.

Hormonal therapy would be an additional or second-line treatment as it focuses on treating the root cause of the symptoms. Moisturizers and lubricants are still considered the first line, but if symptoms persist, hormonal therapy may be necessary. Hormonal replacement therapy may be systemic (oral estrogen replacement) or localized (intravaginal/topical estrogen, estrogen intravaginal releasing ring, and vaginal dehydroepiandrosterone (DHEA, testosterone). Studies show that systemic hormonal replacement therapy alleviates symptoms in 75% of cases, whereas local therapy does so in 80%-90% of cases ⁷⁴⁾. Side effects are comparable but local hormonal replacement therapy is considered much safer than systemic hormonal replacement therapy ⁷⁵⁾.

Hormonal therapy risks should be evaluated thoroughly and factors such as age, duration of use, dose, type of treatment, route, histologic type of cancer and prior exposure should be considered before the prescription of such regimen in survivors of gynecological cancer ⁷⁶⁾. Breast cancer is a hormone-sensitive cancer in many cases; hence, systemic hormonal therapy is not usually recommended for women with breast cancer ⁷⁷⁾, ⁷⁸⁾. As far as endometrial cancer survivors are concerned, the data, although limited, suggest that hormonal therapy is considered relatively safe in low-risk subtypes (i.e., early-stage, low-grade, or type 1), but should not be employed in high-risk types ⁷⁹⁾, ⁸⁰⁾. Similarly, in survivors of epithelial ovarian cancer, hormonal treatment could be considered in selected cases, since evidence suggests a neutral effect in survival; but it should be avoided in certain histologic types, such as advanced serous and endometrioid and other estrogen-sensitive tumor types ⁸¹⁾, ⁸²⁾.

Table 2. Nonhormonal treatment for genitourinary syndrome of menopause

Treatment strategy	Specific therapy	Typical use	Comments
Education	Provide education on potential vulvar and vaginal changes associated with menopause or other low-estrogen states Offer therapy as indicated	General patient education	Education should be offered to women regardless of partner status Regular, painless sexual activity or vaginal stimulation can help maintain sexual function
Lubricants	Examples of lubricants: YES, JO, Good Clean Love, Pink, and Uberlube	Used as needed for sexual activity	Used to increase comfort and pleasure Avoid irritants (eg, glycerin, parabens, and propylene glycol) Can be used with other therapies (hormonal and nonhormonal)
Moisturizers	Examples of moisturizers: Replens, RepHresh, Sliquid Satin, and Hyalo Gyn	Used daily or every few days on a regular basis to maintain vulvar and vaginal moisture	Mimic normal vaginal secretions Do not reverse cellular and pH changes of GSM Can be used with other therapies (hormonal and nonhormonal)
Use of dilators and vibrators	Multiple types available	Used as needed	Gently stimulate and stretch the vulvar and vaginal tissues to maintain function
Pelvic floor physical therapy	Provide education as indicated on kinesthetic awareness, pelvic floor muscle relaxation, manual therapies, and biofeedback	Used as needed for nonrelaxing pelvic floor muscle dysfunction	Find a physical therapist who specializes in pelvic floor disorders (https://www.aptapelvichealth.org)
Topical lidocaine	4% aqueous lidocaine	Applied to the vestibule a few minutes before sexual activity	Can be used as an adjunct to other therapies, including lubricants, moisturizers, and physical therapy
Laser therapy	Carbon dioxide laser Erbium:YAG laser	Administered as a series of 3 treatments a few weeks apart	Use is limited by a lack of studies examining long-term safety and efficacy and comparing laser therapy with estrogen therapy and sham control

Over-the-counter water-based vaginal lubricants and vaginal moisturizers

According to the generally accepted international standards, the first-line recommendations for the treatment of mild and moderate manifestations of genitourinary syndrome of menopause are nonhormonal vaginal lubricants that should be used before intercourse and vaginal moisturizers with a long-term effect that are used regularly (several times a week); in such cases, regular sexual activity is important in maintaining the health and integrity of the vaginal epithelium and flora ⁸⁴⁾, ⁸⁵⁾. This treatment option is also recommended for women for whom the use of vaginal estrogen preparations is unacceptable ⁸⁶⁾. When choosing lubricants and moisturizers, it is important that the product is similar to vaginal secretion in terms of osmolality, pH, and composition ⁸⁷⁾. Vaginal lubricants and moisturizers can be used as needed in combination with other genitourinary syndrome of menopause treatments.

To treat genitourinary syndrome of menopause, your doctor may first recommend over-the-counter treatment options, including:

• Vaginal moisturizers. Try a vaginal moisturizer (K-Y Liquibeads, Replens, Sliquid, others) to restore some moisture to your vaginal area and reduce the pH. You may have to apply the moisturizer daily or every 2–3 days, depending on the extent of your symptoms ⁸⁸⁾. The effects of a moisturizer generally last a bit longer than those of a lubricant. According to Chen et al ⁸⁹⁾, the use of hyaluronic acid vaginal gel every 3 days causes improvement in symptoms of vaginal dryness, comparable with the effect of topical estrogen therapy.
• Water-based lubricants. These water-based lubricants (Astroglide, K-Y Jelly, Sliquid, others) are applied just before sexual activity and can reduce discomfort during intercourse. Vaginal water-based lubricants provide a short-term relief from vaginal dryness and discomfort during sexual intercourse. Choose products that don’t contain glycerin or warming properties because women who are sensitive to these substances may experience irritation. Avoid petroleum jelly or other petroleum-based products for lubrication if you’re also using condoms, because petroleum can break down latex condoms on contact. Lubricants with a water base have fewer side effects, which is an advantage compared to lubricants based on silicone ⁹⁰⁾. The literature contains sparse data on the safety of lubricants based on oils, the effect on motility of spermatozoa, and the properties of condoms. There is also evidence of an increased risk of developing bacterial vaginosis and vaginal candidiasis with the use of these medications ⁹¹⁾, ⁹²⁾, ⁹³⁾.
• Allow time to become aroused during intercourse. The vaginal lubrication that results from sexual arousal can help reduce symptoms of dryness or burning.

If those options don’t ease your symptoms, your doctor may recommend:

Topical estrogen

Vaginal estrogen has the advantage of being effective at lower doses and limiting your overall exposure to estrogen because less reaches your bloodstream. Vaginal estrogen may also provide better direct relief of symptoms than oral estrogen does.

Vaginal estrogen therapy comes in a number of forms. Because they all seem to work equally well, you and your doctor can decide which one is best for you ⁹⁵⁾, ⁹⁶⁾.

• Vaginal estrogen cream (Estrace, Premarin). You insert this cream directly into your vagina with an applicator, usually at bedtime. Typically women use it daily for one to three weeks and then one to three times a week thereafter, but your doctor will let you know how much cream to use and how often to insert it.
• Vaginal estrogen suppositories (Imvexxy). These low-dose estrogen suppositories are inserted about 2 inches into the vaginal canal daily for weeks. Then, the suppositories only need to be inserted twice a week.
• Vaginal estrogen ring (Estring, Femring). You or your doctor inserts a soft, flexible ring into the upper part of the vagina. The ring releases a consistent dose of estrogen while in place and needs to be replaced about every three months. Many women like the convenience this offers. A different, higher dose ring is considered a systemic rather than topical treatment.
• Vaginal estrogen tablet (Vagifem). You use a disposable applicator to place a vaginal estrogen tablet in your vagina. Your doctor will let you know how often to insert the tablet. You might, for instance, use it daily for the first two weeks and then twice a week thereafter.

According to the North American menopausal community, when taking low-dose vaginal estrogen preparations, the following occur: a decrease in the rugae of the vagina, an increase in the number of lactobacilli, and an improvement in the state of the vaginal epithelium and the epithelium of the urethra ⁹⁷⁾. When administering local estrogen preparations, it is necessary to remember the side effects of drugs associated with systemic adsorption. Excess estrogen levels in postmenopausal women are associated with an increased risk of heart disease, breast cancer, thromboembolic complications, and cerebrovascular diseases ⁹⁸⁾. Preference should be given to low-dose local estrogens, especially if the therapy is prescribed to aged patients.

The most commonly used form of local estrogen therapy is vaginal creams based on conjugated equine estrogens and 17b estradiol; they provide a good moisturizing effect. However, the amount of cream administered can vary, exceeding the recommended daily dosage, which is particularly undesirable for patients at high risk. According to data of Kingsberg et al ⁹⁹⁾, several women experience discomfort when using vaginal cream, finding it messy.

If more controlled dosing of estrogen is required, the drug of choice may be vaginal tablets containing 10 mg of estradiol.

During the first 2 weeks of use, the daily use of the above-mentioned drug groups is recommended, followed by a transition to maintenance therapy with a dose of two to three times a week ¹⁰⁰⁾.

Sustained-release estradiol vaginal rings are preferred for women for whom daily use of drugs is unacceptable. Vaginal rings are inserted for up to 90 days and can be independently installed and removed by the patient. However, depending on the daily dose of estrogens, such systems can facilitate not only urogenital symptoms, but also vasomotor symptoms of menopause ¹⁰¹⁾.

The use of vaginal rings is not recommended in women with prolapse of the genitals. It is also necessary to warn a woman about the possible expulsion of the vaginal ring.

In the studies of Constantine et al ¹⁰²⁾, Simon et al ¹⁰³⁾, and Pickar et al ¹⁰⁴⁾, a good result regarding the rapid relief from the genitourinary syndrome of menopause symptoms was noted when using gel capsules with estradiol, released at a dose of 4, 10, and 25 µg. At the same time, the absorption of the drug into the systemic circulation and the maximum concentration of estradiol in the serum were significantly lower in comparison with the use of vaginal tablets. The authors noted relief from the main symptoms of genitourinary syndrome of menopause for a few weeks after the use of vaginal capsules, but in most cases, it took up to 12 weeks of therapy to completely relieve the symptoms. However, clinical observations of the use of this group of low-dose estrogens are limited to 1 year.

Several clinical studies have also noted improvements in urinary symptoms, such as urgency, frequency, nocturia, and stress and urgency urinary incontinence ¹⁰⁵⁾.

Very interesting are the data published by Santen ¹⁰⁶⁾, where various variants of local estrogen therapy (low-, intermediate-, and high-dose) and their adsorption into the systemic circulation are considered. The author compared the peak concentrations of estrogens and the “chronic concentration” of estrogens in the blood plasma as a result of adsorption with prolonged use. According to data analysis of more than 30 studies, the use of low-dose vaginal estrogens (7.5 µg silastic vaginal ring and a 10 µg estradiol tablet [eg, VagifemR]) showed adsorption to the systemic circulation, but during long-term administration the estradiol levels were <20 pg/mL ¹⁰⁷⁾.

Absorption of low-dose vaginal estrogen preparations into the systemic blood stream is minimal and serum estradiol level does not exceed the physiological value for the postmenopausal period ¹⁰⁸⁾. Such a route of administration of drugs allows to avoid hepatic metabolism, which minimizes the risk of side effects inherent in systemic estrogen therapy and excludes the effects on the endometrium and breast tissue, and thus, there is no need to prescribe progesterone preparations for the prevention of endometrial hyperplasia and adenocarcinoma. Local estrogen therapy allows to quickly eliminate the symptoms of genitourinary syndrome of menopause, but it does not alleviate the vasomotor symptoms and reduce the risk of osteoporosis ¹⁰⁹⁾. However, according to several authors, against the background of long-term use of low-dose local estrogens, systemic effects on bone resorption and serum lipid were observed ¹¹⁰⁾, ¹¹¹⁾.

Ospemifene (Osphena)

Selective estrogen receptor modulators (SERMs) are another option for genitourinary syndrome of menopause treatment among women in whom estrogen preparations are contraindicated. Selective estrogen receptor modulators (SERMs) are structurally different and interact with intracellular estrogen receptors in the target organs as agonists or antagonists of estrogens.

In 2013, Ospemifene (Osphena) was approved for use by the US Food and Drug Administration (FDA) and is now successfully used in USA and Europe. The literature has already accumulated sufficient reports on the use of oral ospemifene. Taken daily, oral ospemifene 60 mg daily can help relieve painful sex symptoms in women with moderate to severe genitourinary syndrome of menopause (GSM). It is not approved in women who’ve had breast cancer or who have a high risk of developing breast cancer.

Ospemifene has relatively weak estrogenic and antiestrogenic effects in classical hormonal tests, has an anti-osteoporosis effect, and reduces the level of total cholesterol.

A comparable effect with vaginal estrogens has been noted regarding alleviating the symptoms of vaginal atrophy and dyspareunia, improving the vaginal epithelium and pH of the vagina ¹¹²⁾. The results of the studies with ospemifene show significant increase in the percentage of surface cells of the vaginal epithelium and a decrease in the percentage of parabasal cells and a decrease in vaginal pH ¹¹³⁾.

Constantine et al ¹¹⁴⁾, in their double-blind, placebo-controlled study, found the efficacy and safety within 1 year of using ospemifene. No cases of endometrial cancer were reported and only <1% of patients had endometrial hyperplasia. The incidence of thromboembolism associated with ospemifene in the pivotal studies was comparable to placebo; however, as a SERM, the class effect regarding the increased risk of venous thrombosis should be considered and this drug should be avoided in patients with an increased risk of venous thrombosis.

Lasofoxifene is new third-generation SERM that binds to both estrogen receptor types and is currently not approved for use by the FDA ¹¹⁵⁾. Lasofoxifene has a pronounced positive effect on the state of the vaginal epithelium and pH and provides relief from the main symptoms of genitourinary syndrome of menopause in comparison to taking placebo ¹¹⁶⁾. A number of studies have shown the high efficacy of lasofoxifene in improving bone mineral density, as well as reducing the risk of coronary heart disease and stroke and alleviating the symptoms of genitourinary syndrome of menopause ¹¹⁷⁾, ¹¹⁸⁾, ¹¹⁹⁾, ¹²⁰⁾.

A tissue-specific estrogen complex is now being developed, including a combination of SERM (bazedoxifene) with conjugated estrogens. In the literature, there is evidence of the drug causing significant relief from the symptoms of genitourinary syndrome without the development of endometrial hyperplasia ¹²¹⁾, ¹²²⁾.

The effect of tamoxifen in the vaginal epithelium is not well established; however, most of the data demonstrated that tamoxifen exerts antiestrogenic effect on the vaginal epithelium. Raloxifene slightly increased the percentage of vaginal superficial cells and decreased the percentage of parabasal cells; however, raloxifene did not improve the symptom of painful sex (dyspareunia) ¹²³⁾.

Intravaginal dehydroepiandrosterone (DHEA) – Prasterone (Intrarosa)

These vaginal inserts deliver the hormone dehydroepiandrosterone (DHEA) directly to the vagina to help ease painful sex (dyspareunia). For the daily vaginal use of DHEA, Intrarosa (prasterone) (6.5 mg) was recently approved by the FDA for use in the treatment of painful sex (dyspareunia). DHEA is a steroid precursor hormone (prohormone) with weak androgenic effects that is converted into male sex hormone (testosterone) and/or female sex hormone (estrogens) in peripheral tissues in your body to exert their effects ¹²⁴⁾, ¹²⁵⁾. Prasterone or DHEA is used nightly for moderate to severe vaginal atrophy.

The vaginal metabolism of DHEA into estrogens/testosterone leads to the activation of estrogen and androgen receptors in the three layers of the vaginal wall, including the fibers of the basal membrane collagen and the muscle wall, but the absence of aromatase in the normal endometrium does not lead to its stimulation ¹²⁶⁾. The levels of estradiol and testosterone in the serum may have minimal increases, without clinical significance presumably because of local inactivation. There is a slight increase in the serum concentration of DHEA sulfate (DHEAS).

In a new prospective, randomized, double-blind clinical trial, Labrie et al ¹²⁷⁾ confirmed the local beneficial effect of intravaginal DHEA (prasterone) on the symptoms of mild or severe dyspareunia, the most frequent manifestation of genitourinary syndrome in postmenopausal women.

Systemic estrogen therapy

If vaginal dryness is associated with other symptoms of menopause, such as moderate or severe hot flashes, your doctor may suggest estrogen pills, patches or gel, or a higher dose estrogen ring. Estrogen taken by mouth enters your entire body. Ask your doctor to explain the risks versus the benefits of oral estrogen, and whether or not you would also need to take another hormone called progestin along with estrogen. Estrogen therapy is prescribed after a clinical examination, identifying the risk factors for possible complications, and explaining the information to the patient. Low doses of estrogens are preferred for use, since the use of high doses of estrogen in menopausal age is associated with a high risk of hyperproliferative endometrial and adenocarcinoma ¹²⁸⁾.

Studies have shown that systemic estrogen therapy eliminates the symptoms of vaginal atrophy in 75% of cases, while local therapy does so in 80%–90% of cases ¹²⁹⁾.

Vaginal dilators

You may use vaginal dilators as a nonhormonal treatment option. Vaginal dilators may also be used in addition to estrogen therapy. Lubricated vibrator or vaginal dilator stimulate and stretch the vaginal muscles to reverse narrowing of the vagina. In women who experience vaginismus (ie, the involuntary contraction of the muscles surrounding the vagina), the progressive use of vaginal dilators with relaxation and mindfulness exercises can facilitate reinitiation of painless penetrative sexual activity ¹³⁰⁾. If painful sex is a concern, vaginal dilators may relieve vaginal discomfort by stretching your vagina. They are available without a prescription, but if your symptoms are severe, your doctor may recommend pelvic floor physical therapy and vaginal dilators. Pelvic floor physical therapy, ideally provided by a physical therapist with specialized training in pelvic floor disorders, may be useful for treatment of women with nonrelaxing or high-tone pelvic floor muscle dysfunction triggered by painful sexual activity related to genitourinary syndrome of menopause ¹³¹⁾. Your health care provider or a pelvic physical therapist can teach you how to use vaginal dilators. Use this link to find a physical therapist who specializes in pelvic floor disorders (https://www.aptapelvichealth.org)

Topical lidocaine

Available as a prescription ointment or gel, topical lidocaine (topical local anesthetic) can be used to lessen discomfort associated with sexual activity. Apply it five to 10 minutes before you begin sexual activity.

Topical lidocaine applied to the entrance of the vagina a few minutes before sexual activity has reduced pain with sexual activity in breast cancer survivors and may serve as an adjunct to other therapies (eg, vaginal moisturizers, lubricants, and physical therapy) for management of GSM ¹³²⁾.

Systemic or local testosterone

Studies on the effects of androgens on the genitourinary system have mainly been conducted in animals ¹³³⁾. Several studies have demonstrated that androgens play an important role in the human urogenital system ¹³⁴⁾, but data so far are scarce. In a study by Salinger ¹³⁵⁾, menopausal women aged 54 to 85 years were administered intramuscular testosterone propionate daily or every other day to a total of 125 mg over 1 week. Subsequently, vaginal tissue biopsy was performed to evaluate the hormonal effect—vaginal superficial cells, epithelial intermediates, and glycogen deposition were increased ¹³⁶⁾. However, current studies of systemic transdermal testosterone therapy, alone or in combination with estrogen treatment, have not proven its effects on vaginal health ¹³⁷⁾, ¹³⁸⁾.

A study of postmenopausal women using intravaginal testosterone showed decreased vaginal pH and increased vaginal lactobacilli compared to the group using lubricating gel ¹³⁹⁾. Another study compared the group using intravaginal testosterone (5 mg/dose) in combination with conjugated equine estrogen with the group using conjugated equine estrogen alone. However, as conjugated equine estrogen was administered to both groups, there was a limitation in elucidating the effect of vaginal testosterone alone ¹⁴⁰⁾.

According to the 2020 position statement of the North American Menopause Society, to date, there is not enough data to confirm the safety and efficacy of systemic local testosterone therapy for the treatment of GSM ¹⁴¹⁾. To date, hypoactive sexual desire disorder/dysfunction is the only evidence-based indication for testosterone use in postmenopausal women ¹⁴²⁾.

Women with breast cancer

If you have a history of breast cancer, tell your doctor and consider these options:

• Nonhormonal treatments. Try moisturizers and lubricants as a first choice.
• Vaginal dilators. Vaginal dilators are a nonhormonal option that can stimulate and stretch the vaginal muscles. This helps to reverse narrowing of the vagina.
• Vaginal estrogen. In consultation with your cancer specialist (oncologist), your doctor might recommend low-dose vaginal estrogen if nonhormonal treatments don’t help your symptoms. However, there’s some concern that vaginal estrogen might increase your risk of the cancer coming back, especially if your breast cancer was hormonally sensitive.
• Systemic estrogen therapy. Systemic estrogen treatment generally isn’t recommended, especially if your breast cancer was hormonally sensitive.

More than 60% of postmenopausal women with breast cancer report symptoms of GSM ¹⁴³⁾. Management of women with breast cancer, particularly those with estrogen receptor (ER) positive breast cancer, poses a challenge. These women often experience profound symptoms of GSM, but treatment options are limited. Women at high risk for breast cancer or those with estrogen receptor (ER)-positive breast cancers who are taking tamoxifen with persistent or severe symptoms not responding to non-hormonal therapies may be offered low-dose vaginal estrogen therapies, provided they have factors indicating a low risk of recurrence ¹⁴⁴⁾. Most oncologists are opposed to the use of even vaginal estrogen in women taking aromatase inhibitors; however, if symptoms are profound following discussion with their oncologist and there is recognition that even a small amount of estrogen absorbed may impact the effectiveness of the aromatase inhibitor on some occasions, low-dose vaginal estrogen therapy may be considered ¹⁴⁵⁾. The use of vaginal estrogen in women with a history of triple-negative disease is theoretically reasonable, but data are lacking ¹⁴⁶⁾.

Vaginal laser therapy

Recently introduced in the treatment of genitourinary syndrome of menopause, laser vaginal therapy has demonstrated effectiveness as well as high satisfaction among patients and health care providers ¹⁴⁷⁾, ¹⁴⁸⁾, ¹⁴⁹⁾, ¹⁵⁰⁾, ¹⁵¹⁾, ¹⁵²⁾, ¹⁵³⁾, ¹⁵⁴⁾. Although the carbon dioxide laser has been cleared by the US Food and Drug Administration (FDA) for “incision, excision, ablation, vaporization, and coagulation of body soft tissues in medical specialties, including aesthetic (dermatology and plastic surgery), podiatry, otolaryngology (ENT), gynaecology” and other specialties and the YAG laser has been cleared for “incision, excision, ablation, vaporization of soft tissue for General Dermatology, Dermatologic and General Surgical procedures for coagulation and hemostasis,” vulvovaginal atrophy or genitourinary syndrome of menopause is not specifically listed as an indication for treatment ¹⁵⁵⁾, ¹⁵⁶⁾, ¹⁵⁷⁾. On July 30, 2018, the FDA released an FDA Safety Communication1 with the goal of alerting patients and healthcare providers to the fact that the use of energy-based devices (such as radiofrequency or laser) approved to treat gynecologic conditions but are also being used for various vaginal procedures such as vaginal “rejuvenation,” vaginal cosmetic procedures, and procedures intended to treat vaginal conditions and symptoms related to menopause, as well as for urinary incontinence or sexual function may be associated with serious adverse events ¹⁵⁸⁾, ¹⁵⁹⁾. Longer-term safety and efficacy studies using sham controls are needed before laser treatments can be recommended as a standard therapy for genitourinary syndrome of menopause ¹⁶⁰⁾, ¹⁶¹⁾. Based on the available scientific evidence, with no supporting long term follow-up data, the use of laser should, at present, not be recommended for the treatment of vaginal atrophy, vulvodynia or lichen sclerosus ¹⁶²⁾, ¹⁶³⁾, ¹⁶⁴⁾. The data for the role of laser for stress urinary incontinence and vaginal laxity are inadequate to draw any conclusions or safe practice recommendations. Therefore based on the available scientific evidence and on the lack of long term follow-up, the use of laser should not be recommended for the treatment of vaginal atrophy, vulvodynia, lichen sclerosus, stress urinary incontinence, vaginal prolapse, or vaginal laxity ¹⁶⁵⁾.

Laser therapy improves the vascularization of the vaginal mucosa, stimulates the synthesis of new collagen and matrix basic substance in the connective tissue, thickens the vaginal epithelium with the formation of new papillae, replenishes glycogen in the vaginal epithelium, allows restoring the balance of the mucosa and therefore improves the symptoms of atrophy caused by a lack of estrogen ¹⁶⁶⁾, ¹⁶⁷⁾, ¹⁶⁸⁾.

Salvatore et al ¹⁶⁹⁾ also noted a significant improvement in the quality of life and sexual activity when laser therapy was used in women with genitourinary syndrome of menopause. In the study of Salvatore et al ¹⁷⁰⁾, 85% of women who were previously not sexually active due to genitourinary syndrome of menopause symptoms regained a normal sexual life at 12 weeks following therapy. The positive effect in the treatment of women with genitourinary syndrome of menopause can be achieved by combining hormonal and non-hormonal methods of treatment. It is important not to forget about the positive effect of sexual intercourse on the improvement of vaginal health. For the women who do not have regular sexual intercourse or have vaginal narrowing, the phenomenon of vaginismus, gradual careful stretching of the vagina with special vaginal dilators using lubricants is recommended. It can play an important role in restoring and maintaining the vaginal function. Then, the resumption of regular sexual activity will help to maintain vaginal health. Many women with these disorders benefit from the exercises that strengthen the muscles of the pelvic floor. In those patients, the use of vaginal estrogens before and after the expansion of the vagina and/or therapy to strengthen the pelvic muscles may be useful.

Radiofrequency therapy

With high-frequency alternating current, radiofrequency can temporarily increase the intracellular temperature, leading to cellular membrane rupture. This leads to neo-collagenesis of the vaginal mucosal wall; this is a mechanism similar to that of laser treatment. A pilot study showed that 14 women with genitourinary syndrome of menopause, treated with microablative fractional radiofrequency 3 times with a 1-month interval, experienced improvement in symptom severity and sexual satisfaction ¹⁷¹⁾. However, this energy-based device is also not FDA approved for the treatment of genitourinary syndrome of menopause, and more studies are needed ¹⁷²⁾.

Education

Education is important so that women know about the genitourinary changes that occur with the loss of estrogen associated with menopause. Patients should be advised that genitourinary syndrome of menopause symptoms are unlikely to improve without treatment, and counseling should include a review of treatment options, both nonhormonal and hormonal ¹⁷³⁾. Women who are sexually active are often aware of these gradual changes, which may cause discomfort with sexual activity, but sexually inactive women who have genitourinary syndrome of menopause and who resume sexual activity may be surprised that it is painful (or not even possible) ¹⁷⁴⁾. Regular, painless sexual activity can help maintain vaginal health. A vibrator can be used therapeutically to stimulate blood flow and maintain vaginal function in women with or without a partner ¹⁷⁵⁾.

Alternative medicine

Some alternative medicines such as oral vitamin D, vaginal vitamin E, and probiotics are used to treat vaginal dryness and irritation associated with menopause, but few approaches are backed by sufficient evidence from clinical trials ¹⁷⁶⁾, ¹⁷⁷⁾, ¹⁷⁸⁾, ¹⁷⁹⁾. Interest in complementary and alternative medicine is growing, and researchers are working to determine the benefits and risks of various alternative treatments for genitourinary syndrome of menopause.

Talk with your doctor before taking any herbal or dietary supplements for perimenopausal or menopausal symptoms. The Food and Drug Administration (FDA) doesn’t regulate herbal products, and some may interact with other medications you take, putting your health at risk.

Genitourinary syndrome of menopause prognosis

Women suffering from genitourinary syndrome of menopause are able to get significant symptomatic relief with treatment if diagnosed and educated. Women who do not undergo management will, unfortunately, continue to experience ongoing symptoms, which can increase frustration, poor sexual lifestyle, recurrent infections, and overall lead to a decreased quality of life ¹⁸⁰⁾. Without treatment, your vaginal atrophy may get worse. Occasionally, vaginal atrophy can become so severe that it can significantly narrow your vaginal opening. This may make it harder to treat the vaginal atrophy if treatment is started too late.

Living with genitourinary syndrome of menopause

Vaginal atrophy can seriously affect your quality of life in general, not just your sex life ¹⁸¹⁾. The pain, dryness, burning/itching, spotting, bleeding, urinary problems, urinary tract infections (UTIs) and discharge can make you very uncomfortable and interfere with your daily living. One in 4 people report that vaginal atrophy has had a negative impact on other areas of their lives including their sleep, sexual health and general happiness.

Can genitourinary syndrome of menopause be reversed?

Genitourinary syndrome of menopause can’t be cured, but you don’t have to live with the discomfort. With proper diagnosis and treatment, the symptoms can be managed. Women who do not undergo management will, unfortunately, continue to experience ongoing symptoms, which can increase frustration, poor sexual lifestyle, recurrent infections, and overall lead to a decreased quality of life ¹⁸²⁾. Without treatment, your vaginal atrophy may get worse. Occasionally, vaginal atrophy can become so severe that it can significantly narrow your vaginal opening. This may make it harder to treat the vaginal atrophy if treatment is started too late.
