Atrophic vaginitis is inflammation of the vagina as a result of tissue thinning due to low estrogen levels. [2] Symptoms may include pain with sex, vaginal itchiness or dryness, and an urge to urinate or burning with urination. [1] [3] It generally does not resolve without ongoing treatment. [1] Complications may include urinary tract infections. [1] Atrophic vaginitis as well as vulvovaginal atrophy, bladder and urethral dysfunctions are a group of conditions that constitute genitourinary syndrome of menopause (GSM). [4] Diagnosis is typically based on symptoms. [1]
The decrease in estrogen typically occurs following menopause. [1] Other causes may include breastfeeding or using specific medications. [1] Risk factors include smoking. [2]
Treatment for atrophic vaginitis may involve the use of topical estrogen or other estrogen replacement. To treat the symptoms, patients may use lubricants, but it may not help long term as it does not affect the tissues. [5]
In a majority of postmenopausal women, there are risk factors that can contribute to atrophic vaginitis. Specifically, these risk factors are directly related to decreased estrogen levels and vaginal health. Some risk factors include
All of these factors impact estrogen levels and vaginal health, causing an increase in Atrophic vaginitis development.
Atrophic vaginitis may be caused by tissue thinning, loss of elasticity, and loss of vaginal fluids from low estrogen levels. [5] Normally, estrogen helps the vagina shed old cells, which are then converted into lactic acid by good bacteria. [15] This keeps the vagina's pH acidic and healthy. [15] When estrogen levels drop, this process slows down, leading to thinner vaginal tissue, less moisture, and a less acidic environment. [15] As a result, there's a higher risk of getting vaginal and urinary tract infections. [15] Normal menopause and treatments such as chemotherapy or medications may result in loss of estrogen.
Those with or had a history of breast cancer may be at a higher risk of developing atrophic vaginitis due to chemotherapy and other endocrine treatments. [4] Estrogen is crucial for women's sexual and urinary health. [16] It supports the tissues in the lower vagina and urinary tracts to keep them thick, elastic, and moist and ensuring good blood flow. [16] [17] Estrogen helps maintain a thick, glycogen-rich vaginal lining, which healthy bacteria use to produce lactic acid to keep the vaginal environment acidic, reducing infection risks. [16] In premenopausal women, the main form of estrogen is called estradiol and fluctuates between 40 and 200 pg/mL, rising to 600 pg/mL during ovulation. [16] Postmenopause, estrogen levels drop significantly tp 5-18 pg/mL, leading to gradual changes in the urogenital area. [16] All tissue types such as connective, epithelial, muscular, blood vessels, and nerves are affected and become thinner and less effective, which increases risk of infections, inflammation, injuries, and sores. [16] Blood flow and sensation can decrease, causing pain during sex and the pH level can rise due to decreased lactic acid production, which can allow harmful bacteria and fungi to grow and cause infections. [16]
Antiestrogen medications may also contribute to the development of atrophic vaginitis. These medications include danazol, nafarelin, and medroxyprogesterone. Additional risk factors include smokers, those who have not given birth naturally (through the vagina), and increased prolactin levels while lactation. [14]
After menopause the vaginal epithelium changes and becomes a few layers thick. [18] Many of the signs and symptoms that accompany menopause occur in atrophic vaginitis. [3] The earliest symptoms of atrophic vaginitis may be decreased vaginal lubrication, while other symptoms may appear later. [14] Genitourinary symptoms include
It can be challenging to diagnose atrophic vaginitis given that the symptoms are mild and nonspecific for many postmenopausal women. [22] Since women can have signs and symptoms that could be attributed to other causes, diagnosis is based upon the symptoms that cannot be better accounted for by another diagnosis. [19]
To determine if atrophic vaginitis is the cause for a patient's symptoms, differential diagnosis may be used. Other diagnosis include bacterial vaginosis, trichomoniasis, candidiasis, and contact irritation from irritants such as soaps, pantyliners, or tight-fitting clothing. [14] For example, a person who does not feel itching is unlikely to have candidiasis and no odor likely rules out bacterial vaginosis. [23]
Lab tests usually do not provide information that will aid in diagnosing. A visual exam is useful. The observations of the following may indicate lower estrogen levels: little pubic hair, loss of the labial fat pad, thinning and resorption of the labia minora, and the narrowing of the vaginal opening. An internal exam will reveal the presence of low vaginal muscle tone, the lining of the vagina appears smooth, shiny, pale with loss of folds. The cervical fornices may have disappeared and the cervix can appear flush with the top of the vagina. Inflammation is apparent when the vaginal lining bleeds easily and appears swollen. [1]
The vaginal pH will change from being acidic to a more neutral pH at around 4.5 or higher. This is typically taken by placing Litmus test strip on the wall of the vagina. [24] Papillary and reticular, as well as skin and dermal tissue atrophy are observed via histological examinations. Observed reduced vascularization, atrophy of epithelial tissue leading to reduced thickness, and paleness are all apparent in post-menopausal women during histological examinations. [25] Microscopy laboratory tests may be used to rule out symptoms caused by trichomoniasis and other bacteria. [14] A Papanicolaou test, also known as a pap test, would not be useful as it does not correlate strongly with the symptoms of atrophic vaginitis. [26]
The Vaginal Maturation Index (VMI) is a measure used to assess the composition of different types of cells in the vaginal lining. [27] It helps to evaluate the hormonal environment in the vagina by calculating the proportion of different types of cells present in the vagina. [27] During different life stages, such as before the first menstural cycle, during reproductive years, and after menopause, the distribution of these cell types changes. [27] VMI is determined using a specific formula and provides a more comprehensive view of the hormonal effects on the vagina over time than a single hormone level measurement. [27] VMI is particularly useful in clinical research for evaluating the impact of hormone therapy and changes in sexual function during menopause. [27] VMI is also a better measure of vaginal atrophy than patient-reported symptoms of vaginal dryness. [27]
Symptoms of genitourinary syndrome of menopause (GSM) will unlikely be resolved without treatment. [1] Some individuals may have many or a few symptoms so treatment is provided that best suits each person. If other health problems are also present, these can be taken into account when determining the best course of treatment. For those who have symptoms related to sexual activities, a lubricant may be sufficient. [1] [28] If both urinary and genital symptoms exist, local, low-dose estrogen therapy can be effective. Those individuals who are survivors of hormone-sensitive cancer may need to be treated more cautiously. [1] Some people can have symptoms that are widespread and may be at risk for osteoporosis. Estrogen and adjuvants may be best. [28] Recent research showed a medication called ospemifene can be an alternative oral treatment if vaginal products or hormone therapy is not suitable for patients surviving gynecological cancer. [29] Ospemifene can increase collagen production to improve vaginal tissue, which will help reduce GSM symptoms. [29] Studies have shown this medication has helped increase vaginal pH, elasticity, and moisture to improve vaginal health as well as sexual and emotional well-being. [29]
Topical treatment with estrogen is effective when the symptoms are severe and relieves the disruption in pH to restore the microbiome of the vagina. When symptoms include those related to the urinary system, systematic treatment can be used. Recommendations for the use of the lowest effective dose for the shortest duration help to prevent adverse endometrial effects. [28] Treatment is generally with estrogen cream applied to the vagina. [1] The use of estrogen for treatment do come at some risk. Those who are treated with estrogen may be at a higher risk of developing vaginal candidiasis since estrogen allows lactobacilli to increase in levels. [26] Additionally, it is recommended that soaps and other irritants are avoided. [2]
Some treatments have been developed more recently. These include selective estrogen receptor modulators, vaginal dehydroepiandrosterone, and laser therapy. Other treatments are available without a prescription such as vaginal lubricants and moisturizers. Vaginal dilators may be helpful. Since GSM may also cause urinary problems related to pelvic floor dysfunction, the person may benefit from pelvic floor strengthening exercises. The individual and their partners have reported that estrogen therapy resulted in less painful sex, more satisfaction with sex, and an improvement in their sex life. [1] If a person cannot tolerate or use estrogen therapy, topical hyaluronic acid can be used as another option which has been shown to be safe and effective. [30] For mild atrophic vaginitis, hyaluronic acid can be used as a treatment first. [30] However, if it is moderate to severe atrophic vaginitis, estrogen therapy is recommended to be used first. [30] Vitamin E vaginal suppositories were also found to be helpful in relieving symptoms of GSM, but further studies need to be done to evaluate how safe and effective this treatment is for this condition. [31] Other studies have discussed using vaginal oxytocin as a treatment, but there has been no significant effect on GSM in either helping alleviate signs and symptoms or improving the condition. [32]
Atrophic vaginitis develops in 10-50% of postmenopausal women. Of those who are postmenopausal and have developed atrophic vaginitis, 50-70% develop symptoms. [1] [22] Around 30% of women with atrophic vaginitis discuss their symptoms with their primary healthcare provider. It is likely to be under diagnosed and under treated due to lack of awareness of those who are affected by atrophic vaginitis and of healthcare providers. [6] Symptoms of genitourinary syndrome of menopause (GSM) are seen in 65% women one year post-menopause versus 87% six years post-menopause. [22]
Vulvovaginal atrophy and atrophic vaginitis have been the preferred terms for this condition and cluster of symptoms until recently. These terms are now regarded as inaccurate in describing changes to the entire genitourinary system occurring after menopause. The term atrophic vaginitis suggests that the vagina is inflamed or infected. Though this may be true, inflammation and infection are not the major components of postmenopausal changes to the vagina. The former terms do not describe the negative effects on the lower urinary tract which can be the most troubling symptoms of menopause for women. [3] Genitourinary syndrome of menopause (GSM) was determined to be more accurate than vulvovaginal atrophy by two professional societies. [1] [19] [lower-alpha 1] The term atrophic vaginitis does not reflect the related changes of the labia, clitoris, vestibule, urethra and bladder. [19] Overall, the current preferred term is Genitourinary syndrome of Menopause (GSM). It is an umbrella term for vulvovaginal atrophy, atrophic vaginitis, urogenital atrophy and vaginal atrophy. [33]
In 2018, the FDA issued a warning that lasers and other high energy devices were not approved for "rejuvenating" the vagina, and it has received many reports of injuries. [34] Such devices are scams and have been shown to only cause necrosis and extreme pain to lead to suicidal ideation. [35] In a 2021 systematic review, fractionated type CO2 laser therapy used for GSM was shown to be effective and safe in the studies the researchers reviewed. However, there is a lot of evidence still needed to determined how effective this therapy is compared to other treatments for GSM such as hormonal, non-hormonal, and topical treatments. In addition, further studies conducted can also help determine which groups of patients would benefit from CO2 laser therapy. [36]
In addition, there were several studies that looked into whether vaginal oxytocin was an alternative hormone treatment for atrophic vaginitis. In 2023, a systematic review found that there was no significant effect using vaginal oxytocin for this condition. The article explored vaginal maturation index, vaginal pH, endometrial thickness, and dyspareunia. Even though there were lack of evidence to support using vaginal oxytocin for atrophic vaginitis, further studies should be conducted to gain a better understanding of oxytocin's effects and its efficacy on this condition. [32]
A 12-week randomized controlled clinical trial conducted in Ardabil, Iran, in 2018 evaluated the effectiveness of fenugreek extract on atrophic vaginitis in 60 postmenopausal women. [37] Research participants were dividied into an intervention group, which received fenugreek vaginal cream, and a control group, which received conjugated estrogen vaginal cream. [37] The study measured clinical signs and the Vaginal Maturation Index (VMI). [37] The results indicated that while fenugreek extract showed some efficacy in treating atrophic vaginitis, it was significantly less effective that ultra-low-dose estrogen as evidenced by higher VMI scores and greater improvement in clinical signs in the control group. [37]
A 2021 study examined the effectiveness of aloe vera vaginal cream for the treatment of atrophic vaginitis. This randomized, double-blind, controlled trial compared the effectiveness of Aloe Vera vaginal cream to estrogen vaginal cream in treating vaginal atrophy in 60 postmenopausal women. [38] Over six week, both treatments significantly improved symptoms, including vaginal health index (VHI), maturity valve (MV), and overall symptoms of vaginal atrophy. [14] The Aloe Vera group showed a notable increase in superficial cells and superior results in fluid volume compared to the estrogen group. [14] The study concluded that Aloe Vera cream is as effective as estrogen cream, presenting a viable alternative for women who cannot use estrogen therapy. [14]
A 2021 systematic review studied the use of hyaluronic acid for those with postmenopausal vaginal atrophy. From the 833 studies identified, the comparisons of hyaluronic acid to vaginal estrogen treatments appear to have similar safety, tolerability, and efficacy based on outcomes such as vaginal pH and cell maturation. Thus, hyaluronic acid may be a suitable treatment for those who cannot tolerate hormonal treatment. [39]
A 2022 systematic review evaluated randomized controlled trials to see if there were evidence to support the effectiveness of using vaginal Vitamin E and whether it helped alleviate GSM symptoms in postmenopausal individuals. The authors looked into 31 studies and found four of the studies met the requirements for inclusion criteria. One of the trials showed that there was a significant impact in helping alleviate GSM symptoms with using 1 mg vitamin E in the experimental group compared to the placebo group. Another trial showed 5 mg vaginal hyaluronic acid had a greater impact than 1 mg vitamin E. Two of the other trials showed there were no difference between using 0.5 g vaginal estrogen and 100 IU of vaginal vitamin E. Since the authors were only able to use four studies, they encountered some limitations such as using a small number of studies and not having as much evidence. In conclusion, the review article found that vaginal vitamin E can be used to helping with GSM symptom but further studies need to be conducted to confirm its efficacy and safety. [31]
Menopause, also known as the climacteric, is the time when menstrual periods permanently stop, marking the end of reproduction. It typically occurs between the ages of 45 and 55, although the exact timing can vary. Menopause is usually a natural change. It can occur earlier in those who smoke tobacco. Other causes include surgery that removes both ovaries or some types of chemotherapy. At the physiological level, menopause happens because of a decrease in the ovaries' production of the hormones estrogen and progesterone. While typically not needed, a diagnosis of menopause can be confirmed by measuring hormone levels in the blood or urine. Menopause is the opposite of menarche, the time when a girl's periods start.
Dyspareunia is painful sexual intercourse due to medical or psychological causes. The term dyspareunia covers both female dyspareunia and male dyspareunia, but many discussions that use the term without further specification concern the female type, which is more common than the male type. In females, the pain can primarily be on the external surface of the genitalia, or deeper in the pelvis upon deep pressure against the cervix. Medically, dyspareunia is a pelvic floor dysfunction and is frequently underdiagnosed. It can affect a small portion of the vulva or vagina or be felt all over the surface. Understanding the duration, location, and nature of the pain is important in identifying the causes of the pain.
Vaginitis, also known as vulvovaginitis, is inflammation of the vagina and vulva. Symptoms may include itching, burning, pain, discharge, and a bad smell. Certain types of vaginitis may result in complications during pregnancy.
Hot flashes are a form of flushing, often caused by the changing hormone levels that are characteristic of menopause. They are typically experienced as a feeling of intense heat with sweating and rapid heartbeat, and may typically last from two to 30 minutes for each occurrence.
Vaginal bleeding is any expulsion of blood from the vagina. This bleeding may originate from the uterus, vaginal wall, or cervix. Generally, it is either part of a normal menstrual cycle or is caused by hormonal or other problems of the reproductive system, such as abnormal uterine bleeding.
Estradiol acetate (EA), sold under the brand names Femtrace, Femring, and Menoring, is an estrogen medication which is used in hormone therapy for the treatment of menopausal symptoms in women. It is taken by mouth once daily or given as a vaginal ring once every three months.
An estrogen patch, or oestrogen patch, is a transdermal delivery system for estrogens such as estradiol and ethinylestradiol which can be used in menopausal hormone therapy, feminizing hormone therapy for transgender women, hormonal birth control, and other uses. Transdermal preparations of estrogen are metabolized differently than oral preparations. Transdermal estrogens avoid the first pass through the liver and thus potentially reduce the risk of blood clotting and stroke.
Prasterone, also known as dehydroepiandrosterone (DHEA) and sold under the brand name Intrarosa among others, is a medication as well as over-the-counter dietary supplement which is used to correct DHEA deficiency due to adrenal insufficiency or old age, as a component of menopausal hormone therapy, to treat painful sexual intercourse due to vaginal atrophy, and to prepare the cervix for childbirth, among other uses. It is taken by mouth, by application to the skin, in through the vagina, or by injection into muscle.
Vaginal rings are polymeric drug delivery devices designed to provide controlled release of drugs for intravaginal administration over extended periods of time. The ring is inserted into the vagina and provides contraception protection. Vaginal rings come in one size that fits most people.
Hypoestrogenism, or estrogen deficiency, refers to a lower than normal level of estrogen. It is an umbrella term used to describe estrogen deficiency in various conditions. Estrogen deficiency is also associated with an increased risk of cardiovascular disease, and has been linked to diseases like urinary tract infections and osteoporosis.
Vaginal discharge is a mixture of liquid, cells, and bacteria that lubricate and protect the vagina. This mixture is constantly produced by the cells of the vagina and cervix, and it exits the body through the vaginal opening. The composition, amount, and quality of discharge varies between individuals and can vary throughout the menstrual cycle and throughout the stages of sexual and reproductive development. Normal vaginal discharge may have a thin, watery consistency or a thick, sticky consistency, and it may be clear or white in color. Normal vaginal discharge may be large in volume but typically does not have a strong odor, nor is it typically associated with itching or pain. While most discharge is considered physiologic or represents normal functioning of the body, some changes in discharge can reflect infection or other pathological processes. Infections that may cause changes in vaginal discharge include vaginal yeast infections, bacterial vaginosis, and sexually transmitted infections. The characteristics of abnormal vaginal discharge vary depending on the cause, but common features include a change in color, a foul odor, and associated symptoms such as itching, burning, pelvic pain, or pain during sexual intercourse.
Hormone replacement therapy (HRT), also known as menopausal hormone therapy or postmenopausal hormone therapy, is a form of hormone therapy used to treat symptoms associated with female menopause. Effects of menopause can include symptoms such as hot flashes, accelerated skin aging, vaginal dryness, decreased muscle mass, and complications such as osteoporosis, sexual dysfunction, and vaginal atrophy. They are mostly caused by low levels of female sex hormones that occur during menopause.
Vaginal estrogen is a form of estrogen that is delivered by intravaginal administration. Vaginally administered estrogens are thereby exerting their effects mainly in the nearby tissue, with more limited systemic effects compared to orally administered estrogens. It will not protect against osteoporosis. With perhaps the exception of the Femring, it also will not alleviate the hot flashes and hormonal imbalance caused by menopause.
Ospemifene is an oral medication indicated for the treatment of dyspareunia – pain during sexual intercourse – encountered by some women, more often in those who are post-menopausal. Ospemifene is a selective estrogen receptor modulator (SERM) acting similarly to an estrogen on the vaginal epithelium, building vaginal wall thickness which in turn reduces the pain associated with dyspareunia. Dyspareunia is most commonly caused by "vulvar and vaginal atrophy."
Conjugated estrogens (CEs), or conjugated equine estrogens (CEEs), sold under the brand name Premarin among others, is an estrogen medication which is used in menopausal hormone therapy and for various other indications. It is a mixture of the sodium salts of estrogen conjugates found in horses, such as estrone sulfate and equilin sulfate. CEEs are available in the form of both natural preparations manufactured from the urine of pregnant mares and fully synthetic replications of the natural preparations. They are formulated both alone and in combination with progestins such as medroxyprogesterone acetate. CEEs are usually taken by mouth, but can also be given by application to the skin or vagina as a cream or by injection into a blood vessel or muscle.
The vaginal epithelium is the inner lining of the vagina consisting of multiple layers of (squamous) cells. The basal membrane provides the support for the first layer of the epithelium-the basal layer. The intermediate layers lie upon the basal layer, and the superficial layer is the outermost layer of the epithelium. Anatomists have described the epithelium as consisting of as many as 40 distinct layers of cells. The mucus found on the epithelium is secreted by the cervix and uterus. The rugae of the epithelium create an involuted surface and result in a large surface area that covers 360 cm2. This large surface area allows the trans-epithelial absorption of some medications via the vaginal route.
Estriol (E3), sold under the brand name Ovestin among others, is an estrogen medication and naturally occurring steroid hormone which is used in menopausal hormone therapy. It is also used in veterinary medicine as Incurin to treat urinary incontinence due to estrogen deficiency in dogs. The medication is taken by mouth in the form of tablets, as a cream that is applied to the skin, as a cream or pessary that is applied in the vagina, and by injection into muscle.
Estrone (E1), sold under the brand names Estragyn, Kestrin, and Theelin among many others, is an estrogen medication and naturally occurring steroid hormone which has been used in menopausal hormone therapy and for other indications. It has been provided as an aqueous suspension or oil solution given by injection into muscle and as a vaginal cream applied inside of the vagina. It can also be taken by mouth as estradiol/estrone/estriol and in the form of prodrugs like estropipate and conjugated estrogens.
Polyestriol phosphate, sold under the brand names Gynäsan, Klimadurin, and Triodurin, is an estrogen medication which was previously used in menopausal hormone therapy and is no longer available.
Vaginal introital laxity is a symptom of pelvic floor dysfunction characterised by a sensation of looseness at vaginal external opening, also known as the vaginal introitus. Possible causes include pelvic organ prolapse (POP), post-pregnancy and vaginal delivery and menopause. Consequences may include experiencing sexual dysfunction, ranging from dyspareunia, increased vaginal “wind” to overactive bladder (OAB). These consequences may lead to adverse significant impacts on women’s sexual health, body image and quality of life. Vaginal laxity is often underreported, with approximately 80% of women not seeking treatment or discussing their concerns.
