Role of Androgens in Female Genitourinary Tissue Structure and Function: Implications in the Genitourinary Syndrome of Menopause

Insights into the vulvar component of the genitourinary syndrome of menopause (GSM)

Genitourinary syndrome of menopause is a comprehensive term that groups genital, urinary and sexual signs and symptoms mainly due sex hormone deficiency and aging, with a crucial impact on quality of life of midlife women. While this broad definition captures the common underlying physiopathology and the frequent overlap of symptomatology, improving knowledge about different components of genitourinary syndrome of menopause may be relevant for individualized treatment, with possible implications for efficacy, compliance and satisfaction. This narrative review focuses on the vulvar component of genitourinary syndrome of menopause, highlighting anatomical and functional peculiarities of the vulva that are responsible for some of the self-reported symptoms, as well as specific signs at physical examination. Increasing evidence points towards a pivotal role of vulvar vestibular health in the occurrence of sexual pain, one of the most common and distressing symptoms of genitourinary syndrome of menopause, which should be evaluated with validated scales taking a biopsychosocial perspective. This is an essential step in the recognition of different phenotypes of genitourinary syndrome of menopause and in the assessment of the most effective diagnostic and therapeutic algorithm. Menopausal vulvar health deserves more research into tailored non-hormonal and hormonal treatment options.

Effectiveness of Combination of Tibolone and Lactobacilli Plus Lactoferrin in Postmenopausal Women with Vulvar Vestibular Pain: A Preliminary Report

BACKGROUND

Postmenopausal dyspareunia and vulvar pain are common complaints, affecting about 60% of women within a few years after hormone levels begin to decline (such as estrogen and androgen). Atrophic changes mainly located in the vulvar vestibule and vulnerability to vulvovaginal infections in postmenopause could be predisposing factors to the development of vulvar burning/pain and introital dyspareunia (vestibulodynia secondary to atrophy). Tibolone is the most effective and safe alternative for treating menopausal symptoms. The role of Lactobacilli and lactoferrin shows its effectiveness in the treatment of vaginal microbiota dysbiosis. The aim of the present study was to assess the efficacy of the combination of tibolone and an oral-specific Lactobacilli mixture in combination with bovine lactoferrin as synergistic therapy for the treatment of vestibulodynia related to atrophy.

METHODS

In this study, we included 35 postmenopausal women with at least 1 year of amenorrhea, affected by vulvar burning/pain and introital dyspareunia. All participants received treatment with open-label, oral Tibolone 2.5 mg and Lactobacilli mixture (5 × 109 CFU per capsule) in combination with bovine lactoferrin (Respecta®). Each product was taken once daily for 90 days.

RESULTS

After 90 d of therapy with TIB+ Respecta®, in 30 women that completed the treatment, there was a statistically significant decrease from the baseline in the mean of the Visual Analog Scale for vulvar burning/pain and a reduction in scores in the pain evaluation test.

CONCLUSIONS

This study provides evidence that the combination of TIB+ Respecta® was effective in reducing symptoms related to vestibular pain and hypersensitivity in a postmenopausal setting.

Treatment of Prepubertal Labial Adhesions with Topical Estriol + Testosterone: A Case Report

BACKGROUND

Labial adhesions, a frequent gynecological condition in prepubertal girls, occur when the labia minora adhere along the midline. The prevailing hypothesis about their etiology suggests that labial adhesion may occur when the delicate and non-estrogenized labia minora undergo an inflammatory response, triggered by exposure to an irritant environment. Therefore, conservative treatment involves the application of topical estrogen or betamethasone cream. The role of androgens has not been considered yet in the pathophysiology or therapy of this condition. However, some studies have shown that androgen receptors are prevalent in the labia minora and vulvar vestibule.

CASE SUMMARY

We present the case of a 29-month-old girl with symptomatic labial adhesions. She was first ineffectively treated with topical estriol, and then she was treated with a galenic cream containing both estriol and testosterone with complete recovery and without side-effects.

CONCLUSIONS

Both androgens and estrogens play a significant role in maintaining the physiological trophic state of the vulva and vagina, even during childhood. Topical estriol+testosterone could be considered an alternative treatment for prepubertal labial adhesions refractory to standard topical therapy.

Combined estrogen-progestin oral contraceptives and female sexuality: an updated review

INTRODUCTION

Sexual side effects of combined oral contraceptives (COCs) have not been fully understood, but increasing evidence prompts broader risk/benefit evaluation and merits inclusion in counseling on contraceptive options.

OBJECTIVES

The study sought to explore the impact of combined estrogens-progestin oral contraceptives on components of female sexuality, including sexual desire, anatomic genitourinary changes, lubrication, orgasm, provoked vestibulodynia, well-being, body image, partner preference, and relationship stability.

METHODS

A literature review was performed between April 2023 and January 2024 exploring the association between combined oral contraceptive pills and sexual health.

RESULTS

Although COCs decrease free testosterone, it is unclear if COCs affect sexual function, including desire. Antiandrogenic COCs do seem to have a negative effect on sexual arousal, lubrication, and orgasm. Provoked vestibulodynia may be related to early onset of COC use, low-estrogen pills, and antiandrogenic progestins. Emotional and sexual side effects are strong predictors of COC discontinuation. Longitudinal data indicate that using COCs when meeting and selecting a partner has implications on sexual satisfaction and relationship length. Analysis of data is complicated by various doses and forms of estrogen and progestin in COCs, which have changed over time.

CONCLUSION

Lack of randomized placebo-controlled studies and heterogenicity in study design hampers generalized statements about the effects of COCs on sexual function. Despite these challenges, consideration of sexual dysfunction when presenting and prescribing hormonal contraception is essential for informed consent, shared decision making, and ensuring reliable contraceptive choices.

Genitourinary syndrome of lactation: a new perspective on postpartum and lactation-related genitourinary symptoms

BACKGROUND

The genitourinary syndrome of menopause (GSM) is a well-documented condition characterized by a range of genitourinary symptoms in peri- and postmenopausal women. As with GSM, postpartum lactating women experience reduced estrogen and androgen levels. However, there is limited research on the impact of symptoms during the postpartum breastfeeding period.

OBJECTIVES

The aim was to review the literature for genitourinary health in the postpartum breastfeeding population and summarize key findings and potential treatments.

METHODS

We performed a comprehensive literature review in PubMed, Google Scholar, and Scopus from inception of database to November 2023 using the following keywords individually and in combination: "physiology of postpartum" or "physiology of lactogenesis" or "vulvovaginal health" or "vaginal atrophy" or "vaginal dryness" or "dyspareunia" or "urinary incontinence" or "lactation" or "breastfeeding" or "vaginal estrogen." All identified articles published in English were considered. Relevant studies were extracted, evaluated, and analyzed. The work presented in this article represents a summative review of the identified literature.

RESULTS

During lactation, high levels of prolactin inhibit estrogen and androgen secretion via negative feedback, which leads to an increased prevalence of vulvovaginal atrophy, vaginal dryness, dyspareunia, and urinary incontinence in lactating postpartum women. Despite these highly prevalent and potentially devastating symptoms, there is a lack of consistent screening at postpartum visits and no treatment guidelines available to health care providers.

CONCLUSION

Postpartum breastfeeding women experience similar physiology and symptoms to the postmenopausal phase, as seen in GSM. We propose the introduction of a novel term to describe the genitourinary changes seen in postpartum breastfeeding individuals: genitourinary syndrome of lactation. The diagnostic use of genitourinary syndrome of lactation will equip health care providers with an all-encompassing term to bring awareness to the symptoms experienced by postpartum breastfeeding individuals and lead to improved screening and treatment for the high numbers of individuals experiencing these genitourinary changes.

Beyond the discomfort: understanding and managing sexual pain in women, a comprehensive case-based discussion

INTRODUCTION

Sexual pain has a profound impact on individuals, regardless of their sexual orientation or gender identity, and affects women more often than men. It adversely affects both sexual function and interpersonal relationships. Despite its prevalence, sexual pain in women often remains unaddressed and untreated. Various underlying causes contribute to sexual pain, sometimes involving multiple factors. We explore treatment options and offer clinical insights into the evaluation and management of 4 common conditions which cause sexual pain in women. In this article, we use the term "women" to indicate cisgender women.

OBJECTIVES

Our aim is to highlight the most common clinical scenarios of sexual pain and provide comprehensive discussions on each, to improve patient care and outcomes in the management of sexual pain.

METHODS

We conducted a comprehensive review of literature and clinical cases to explore the various causes and management strategies for sexual pain in women. We systematically searched databases such as PubMed, Google Scholar, and relevant medical journals. We included peer-reviewed articles, case studies, and clinical trials published between 2000 and 2023. Additionally, we analyzed real-life cases from our clinical practice at our academic institution.

RESULTS

Our review identified various factors contributing to sexual pain in women, ranging from hormonal imbalances to neuroproliferative and inflammatory conditions affecting the genitourinary system. Each case should be approached individually to offer optimal management strategies accordingly.

CONCLUSION

The management of sexual pain in women requires a comprehensive approach that addresses the multifactorial nature of the condition. Patient education and counseling play a crucial role in the management of sexual pain, empowering individuals to advocate for their own health and well-being. The collaboration between healthcare providers and patients can improve our understanding and management of this complex condition.

Sexual health and contraception in the menopause journey

Women may experience changes in sexuality across menopause, because at this step in life hormone deficiency interacts with several determinants in a bio-psycho-social perspective. Healthcare providers should inform women about menopause impact on sexuality and be proactive during consultation in disclosing sexual concerns that would require a targeted assessment. Sexual symptoms become more frequent as women age, but they do not always translate into sexual dysfunction diagnosis, for which distress is required. It is important to recognize conditions that may increase the risk of dysfunctional response to menopause challenges in order to promote sexual longevity through counselling and specific management. In this review, we report key elements for a comprehensive assessment of sexual health around menopause, with a focus on genitourinary syndrome of menopause (GSM) and hypoactive sexual desire disorder (HSDD), representing well identified clinical conditions affecting sexuality at midlife and beyond. We also address the issue of contraception across the menopausal transition, highlighting risks and benefits, and possible implications on sexual function.

Associations of long-term exposure to air pollution and green space with reproductive hormones among women undergoing assisted reproductive technology: A longitudinal study

Studies investigating the association between long-term exposure to air pollution (AP)/green space and female reproductive hormones are still limited. Furthermore, their interactive effects remain unclear. Our study sought to explore the separate and interactive impacts of AP/green space on reproductive hormones among women undergoing assisted reproductive technology. We measured estradiol (E2), progesterone (P), testosterone (T), and follicle-stimulating hormone (FSH) from the longitudinal assisted reproduction cohort in Anhui, China. The annual mean concentrations of air pollutants were calculated at the residential level. Normalized Difference Vegetation Index (NDVI) within 500-m represented green space exposure. To assess the effect of AP/green space on hormones, we employed multivariable linear mixed-effect models. Our results showed that each one-interquartile range (IQR) increment in particulate matter (PM2.5 and PM10) and sulfur dioxide (SO2) was associated with -0.03[-0.05, -0.01], -0.03[-0.05, -0.02], and -0.03[-0.05, -0.01] decrease in P. An IQR increase in PM2.5, PM10, SO2, and carbon monoxide (CO) was associated with a -0.16[-0.17, -0.15], -0.15[-0.16, -0.14], -0.15[-0.16, -0.14], and -0.12[-0.13, -0.11] decrease in T and a -0.31[-0.35, -0.27], -0.30[-0.34, -0.26], -0.26[-0.30, -0.22], and -0.21[-0.25, -0.17] decrease in FSH. Conversely, NDVI500-m was associated with higher levels of P, T, and FSH, with β of 0.05[0.02, 0.08], 0.06[0.04, 0.08], and 0.07[0.00, 0.14]. Moreover, we observed the "U" or "J" exposure-response curves between PM2.5, PM10, and SO2 concentrations and E2 and P levels, as well as "inverted-J" curves between NDVI500-m and T and FSH levels. Furthermore, we found statistically significant interactions of SO2 and NDVI500-m on E2 and P as well as CO and NDVI500-m on E2. These findings indicated that green space might mitigate the negative effects of SO2 on E2 and P, as well as the effect of CO on E2. Future research is needed to determine these findings and underlying mechanisms.

Vestibular tissue changes following administration of intravaginal prasterone: a vulvoscopic open-label pilot study in menopausal women with dyspareunia

Background

Prasterone, an intravaginal dyspareunia treatment in menopausal women, improves vaginal health through intracellular conversion of dehydroepiandrosterone into androgens and estrogens. Phase 3 trials for prasterone showed significant improvement in vaginal tissue health and reduction of pain.

Aim

To assess vestibular changes with daily use of intravaginal prasterone in menopausal women with moderate to severe dyspareunia.

Methods

This open-label prospective pilot study was conducted over 20 weeks. It included 11 menopausal women (median age, 56 years) who were treated daily with intravaginal inserts of 6.5-mg prasterone and assessed monthly. During vulvoscopy, vestibular pain was assessed by cotton-tipped swab testing, and vestibular and vaginal health was independently assessed with the Visual Scale (VS). In addition, vulvoscopic photographs were obtained and assessed via the Vulvoscopic Genital Tissue Appearance (VGTA) scale to evaluate overall genital tissue health. Mean changes from baseline for genital tissue health and pain assessments were analyzed by repeated measures 1-way analysis of variance, followed by a Dunnett post hoc test. Sexual event diaries were completed and adverse events recorded.

Outcomes

Outcomes included indices of genital tissue health: pain assessment by cotton-tipped swab testing, VS of the vestibule and vagina, VGTA, and sexual event diary.

Results

Aggregate scores from the cotton-tipped swab test progressively improved, reaching statistical significance at week 16, which was maintained through week 20 (-7.27, P = .019). VS scores significantly improved from baseline by week 4 and were maintained through week 20 for the vestibule (-3.00, P = .004) and vagina (-4.00, P = .002). An overall 1607 vulvoscopic photographs were examined; all showed reduction in vestibular erythema and pallor at the end of the study. The mean change from baseline at week 20 for the VGTA score was -7.9 (P = .0016). Intercourse associated with pain was reduced from 81.3% of initiated events during the first month of the study to 8.3% during the last month. Sexual activities that were discontinued due to discomfort were reduced from 45.8% to 6.3%. No prasterone-related serious adverse events were reported.

Clinical Implications

Prasterone, a safe and effective intravaginal hormone treatment, significantly improves vestibular health parameters.

Strengths and Limitations

Strengths are the prospective study design and the use of multiple outcome measures to assess vestibular tissue health and pain associated with sexual activity. Limitations are the small study cohort and use of nonvalidated outcome measures.

Conclusion

Our findings suggest that intravaginal prasterone exerts biologic activity on the androgenic endodermal vestibule, as the medication passes from vagina to vestibule, resulting in amelioration of pain associated with sexual activity.

Advances in the Management of Menopausal Symptoms, Fertility Preservation, and Bone Health for Women With Breast Cancer on Endocrine Therapy

In patients with hormone receptor-positive early-stage breast cancer, adjuvant endocrine treatment administered for up to 5-10 years after diagnosis significantly reduces the risk of recurrence and death. However, this benefit comes with the cost of short- and long-term side effects that may negatively affect patients' quality of life (QoL) and treatment adherence. Among them, the prolonged estrogen suppression associated with the use of adjuvant endocrine therapy in both premenopausal and postmenopausal women can induce life-altering menopausal symptoms, including sexual dysfunction. Moreover, a decrease in bone mineral density and an increased risk of fractures should be carefully considered and prevented whenever indicated. For young women diagnosed with hormone receptor-positive breast cancer with unfulfilled childbearing plans, several challenges should be addressed to manage their fertility and pregnancy-related concerns. Proper counseling and proactive management of these issues are critical components of survivorship and should be pursued from diagnosis through the breast cancer care continuum. This study aims to provide an updated overview of the available approaches for improving the QoL of patients with breast cancer receiving estrogen deprivation therapy, focusing on advances in the management of menopausal symptoms, including sexual dysfunction, fertility preservation, and bone health.

[The role of estriol in the treatment of atrophy of the mucous membrane of the lower genitourinary tract in postmenopausal women]

Studies of recent decades show a steady increase in the average life expectancy of a person, and women in particular. The World Health Organization predicts a four-fold increase in the number of women over 70 by 2030, and many of them over the age of 45 may face menopausal problems. Menopause is a physiological state in a woman's life, during which, against the background of age-related changes, there is a gradual decrease and shutdown of ovarian function and the cessation of estrogen production. Genitourinary syndrome occurs in every third woman in this period. Estriol is the main estrogen that specifically addresses problems associated with estrogen deficiency: dyspareunia, dryness and itching in the vagina and lower genitourinary tract, urinary incontinence, moderate urinary incontinence, and recurrent vulvovaginitis and cystitis. Vulvovaginal dystrophy in women of the older age group is a multidisciplinary problem at the intersection of gynecology, urology and dermatology, which can and should be solved to prevent more severe gynecological and urological pathologies.

Effects of Flibanserin on Subdomain Scores of the Female Sexual Function Index in Women With Hypoactive Sexual Desire Disorder

INTRODUCTION

Flibanserin treatment increases sexual desire and satisfying sexual events while decreasing distress in certain women diagnosed with acquired, generalized hypoactive sexual desire disorder (HSDD). Additional aspects of sexual function and the time course of response have not been fully characterized.

AIM

To evaluate changes in sexual function assessed by the subdomains of the Female Sexual Function Index (FSFI) in women with HSDD treated with flibanserin.

METHODS

FSFI data pooled from 3 pivotal flibanserin trials in premenopausal women (flibanserin = 1,165; placebo = 1,203) and FSFI data from one complete flibanserin trial in postmenopausal women (flibanserin = 432; placebo = 463) were subjected to post-hoc analyses. For each FSFI subdomain, least squares mean change from baseline was calculated at each assessment visit (treatment weeks 4, 8, 16, 24) and treatment groups were compared using analysis of covariance. Standardized effect size (Cohen's d) was also determined for each FSFI subdomain.

MAIN OUTCOME MEASURE

Changes from baseline in FSFI subdomains.

RESULTS

Compared to placebo, both premenopausal (P < .02) and postmenopausal (P < .045) patients in the flibanserin group reported significantly greater increases over baseline in the FSFI subdomain scores of desire, arousal, lubrication, orgasm, and satisfaction. In premenopausal patients, significant improvements were observed at the first assessment of response (week 4) and were maintained through week 24. In postmenopausal patients, significant improvements were observed at week 4 for desire and arousal, while significant improvements in lubrication, orgasm, and satisfaction were observed at week 8. At week 24, excluding the pain subdomain, standardized effect sizes ranged from 0.18 to 0.28 in the premenopausal cohort and 0.12 to 0.29 in the postmenopausal cohort. In both pre- and postmenopausal patients, improvements in pain were smaller and largely undifferentiated between treatment groups.

CLINICAL IMPLICATIONS

While variations in time to response should be taken into consideration, on average, the beneficial impact of flibanserin on overall sexual function occurs within the first month of treatment. The data also suggest that the response to flibanserin is sustained for the duration of treatment.

STRENGTHS AND LIMITATIONS

Sexual function assessments were performed in a large cohort of 2,368 premenopausal women and 895 postmenopausal women. However, the FSFI assesses changes over a 1-month period and time points earlier than 4 weeks could not be assessed.

CONCLUSION

These analyses suggest that assessment of benefit of flibanserin in HSDD should include improvements across all domains of sexual function, not only desire. Simon JA, Clayton AH, Goldstein I, et al.

Revisiting the physiological role of androgens in women

INTRODUCTION

Extensive research underlines the critical functions of androgens in females. Nevertheless, the precise mechanisms of their action are poorly understood. Here, we review the existing literature regarding the physiological role of androgens in women throughout life.

AREAS COVERED

Several studies show that androgen receptors (ARs) are broadly expressed in numerous female tissues. They are essential for many physiological processes, including reproductive, sexual, cardiovascular, bone, muscle, and brain health. They are also involved in adipose tissue and liver function. Androgen levels change with the menstrual cycle and decrease in the first decades of life, independently of menopause.

EXPERT OPINION

To date, studies are limited by including small numbers of women, the difficulty of dosing androgens, and their cyclical variations. In particular, whether androgens play any significant role in regulating the establishment of pregnancy is poorly understood. The neural functions of ARs have also been investigated less thoroughly, although it is expressed at high levels in brain structures. Moreover, the mechanism underlying the decline of dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) with age is unclear. Other factors, including estrogen's effect on adrenal androgen production, reciprocal regulation of ARs, and non-classical effects of androgens, remain to be determined.

Individual Benefits and Risks of Intravaginal Estrogen and Systemic Testosterone in the Management of Women in the Menopause, With a Discussion of Any Associated Risks for Cancer Development

ABSTRACT

Several formulations of intravaginal oestrogen are available for the treatment of genitourinary syndrome of menopause (GSM). These are safe and effective treatments for the symptoms of GSM. Licensed doses of intravaginal oestrogen do not elevate systemic estradiol levels above the normal postmenopausal range with long term use and there is no evidence of an increased risk of coronary heart disease, stroke, thromboembolism, colorectal cancer, endometrial cancer, breast cancer or breast cancer recurrence with their use. This should reassure both women and their healthcare professionals and should lead to more women receiving these localised, vaginally administered hormonal treatments. Available evidence also suggests a positive safety profile for transdermal testosterone treatment when delivered at physiological concentrations.

Relationship of steroid sex hormones with female sexual dysfunction in female patients having urinary incontinence

To investigate serum estradiol, progesterone and dehydroepiandrosterone levels on FSD in females having urinary incontinence (UI), we studied 150 females [100 having UI (50 with FSD and 50 without FSD) and 50 controls]. There were significant lower estradiol and progesterone and higher DHEA serum levels in patients than controls (P = 0.001for all). In UI patients, females having sexual disruption had significantly low levels of estradiol (p = 0.001). Low estradiol serum level represented an isolated predictive factor for sexual dysfunction in incontinent female patients (p = 0.001). A low estradiol serum level might be a possible risk factor for FSD in women having UI.

How Does Contraceptive Use Affect Women's Sexuality? A Novel Look at Sexual Acceptability

Among the components of a healthy life, sexuality is essential, contributing to both the psychophysical and social well-being of women and, consequently, to their quality of life. A poorly investigated standpoint is the acceptability of contraceptive methods, both in terms of their tolerability and metabolic neutrality and in terms of their impact on sexual life. In this context, we will provide an overview of the different methods of contraception and their effects on female sexuality, from biological changes to organic, social, and psychological factors, which can all shape sexuality. A MEDLINE/PubMed review of the literature between 2010 and 2021 was conducted using the following key words and phrases: hormonal contraception, contraceptives, female sexual function, libido, sexual arousal and desire, and sexual pain. Recent studies have supported the effects of contraceptives on women's sexuality, describing a variety of positive and negative events in several domains of sexual function (desire, arousal, orgasm, pain, enjoyment). However, satisfaction with sexual activity depends on factors that extend beyond sexual functioning alone. A more holistic approach is needed to better understand the multitude of factors linked to women's sexuality and contraception. Contraceptive counseling must consider these important elements since they are closely related to good compliance and maximize non-contraceptive health benefits.

Menopause and female sexual dysfunctions (FSDs)

Biological and psycho-relational factors contribute equally to the development of sexual symptoms and associated distress, a key element to diagnose female sexual dysfunctions (FSDs) in menopausal women. Consultation at midlife represents an optimal time to discuss sexual life, and healthcare providers (HCPs) have to be proactive in rising the conversation, as patients may not report their sexual concerns spontaneously. An accurate sexual history is essential to characterize the primary symptom, determine the impact on patient's quality of life and identify risk and precipitating factors. Among FSDs, hypoactive sexual desire disorder (HSDD) is very frequent at midlife together with genitourinary syndrome of menopause (GSM), a chronic condition negatively affecting the full sexual response. A multidimensional approach targeted to the patient's characteristics, goals and expectations is mandatory and should start from educative counselling and correction of modifiable risk factors. When specific treatments are required, they should include non-pharmacological and pharmacological options, often prescribed in combination to address concomitantly the biological and psychosocial components of FSDs.

Swiss consensus on the role of DHEA in the management of genitourinary syndrome of menopause

Genitourinary syndrome of menopause (GSM) has a significantly negative impact on affected women's lives. However, despite the increasing number of GSM treatment options (e.g. non-hormonal vaginal products, vaginal hormones [estrogens], dehydroepiandrosterone [DHEA; prasterone], vaginal laser therapy, oral ospemifene), many women remain untreated. The goal of the Swiss interdisciplinary GSM consensus meeting was to develop tools for GSM management in daily practice: a GSM management algorithm (personalized medicine); a communication tool for vaginal DHEA (drug facts box); and a communication tool for understanding regulatory authorities and the discrepancy between scientific data and package inserts. The acceptance and applicability of such tools will be further investigated.

The role of hormone therapy in urogenital health after menopause

Menopause represents an endocrine challenge to urogenital health, as oestrogens deprivation and androgens decline significantly contributes to age-related involution of vulvovaginal tissues and lower urinary tract. Genitourinary syndrome of menopause (GSM) is a clinical entity including the chronic and progressive condition of vulvovaginal atrophy (VVA) and encompassing both anatomical and functional consequences of menopause. The term GSM describes genital, sexual and urinary symptoms with a detrimental impact on quality of life (QOL). Several treatment options are available, but many barriers are still present to adequately diagnose and treat GSM. This review aims to present current evidences about epidemiology, aetiology, diagnosis and treatment of GSM, with a focus on prescription medications [low-dose local oestrogen therapy (LET), prasterone (DHEA) and the SERM ospemifene] for urogenital symptoms in healthy postmenopausal women and in special populations, including women with premature ovarian insufficiency (POI) and breast cancer survivors (BCS).

Effects of testosterone treatment on clitoral haemodynamics in women with sexual dysfunction

PURPOSE

To explore the effects of 6-month systemic testosterone (T) administration on clitoral color Doppler ultrasound (CDU) parameters in women with female sexual dysfunction (FSD).

METHODS

81 women with FSD were retrospectively recruited. Data on CDU parameters at baseline and after 6 months with four different treatments were available and thus further longitudinally analyzed: local non-hormonal moisturizers (NH group), n = 37; transdermal 2% T gel 300 mcg/day (T group), n = 23; local estrogens (E group), n = 12; combined therapy (T + E group), n = 9. Patients underwent physical, laboratory, and genital CDU examinations at both visits and completed different validated questionnaires, including the Female Sexual Function Index (FSFI).

RESULTS

At 6-month visit, T therapy significantly increased clitoral artery peak systolic velocity (PSV) when compared to both NH (p < 0.0001) and E (p < 0.0001) groups. A similar increase was found in the T + E group (p = 0.039 vs. E). In addition, T treatment was associated with significantly higher FSFI desire, pain, arousal, lubrication, orgasm, and total scores at 6-month visit vs. baseline. Similar findings were observed in the T + E group. No significant differences in the variations of total and high-density lipoprotein-cholesterol, triglycerides, fasting glycemia, insulin and glycated hemoglobin levels were found among the four groups. No adverse events were observed.

CONCLUSION

In women complaining for FSD, systemic T administration, either alone or combined with local estrogens, was associated with a positive effect on clitoral blood flow and a clinical improvement in sexual function, showing a good safety profile.

Sexuality, pelvic floor/vaginal health and contraception at menopause

A multitude of biopsychosocial factors influences sexual health at midlife, a common concern in daily practice along with vaginal and pelvic health. Health-care providers (HCPs) need to be proactive in dealing with possible symptoms because in most cases early management prevents distress and improves quality of life. Female sexual dysfunctions (FSDs) may have a complex etiology but sexual history is not difficult implementing basic knowledge of risk factors and some skills helping women to cope with hormonal and age-related changes. This work summarizes key points to approach sexual symptoms in midlife women, providing principles to diagnose and manage hypoactive sexual desire disorder (HSDD) and genitourinary syndrome of menopause (GSM)/vulvovaginal atrophy (VVA), as well as manage contraceptive needs.

Management of postmenopausal vulvovaginal atrophy: recommendations of the International Society for the Study of Vulvovaginal Disease

OBJECTIVE

To develop a best practice document for the management of postmenopausal vulvovaginal atrophy (VVA).

METHOD

Literature review carried out using clinical terms, treatments or interventions and comorbidity related to VVA.

RESULTS

There is a wide variety of interventions that may produce temporal benefits for VVA. However, there are significant limitations in scientific publications concerning VVA and related issues, including variable outcome evaluations, variability in population age range, and small, often underpowered sample sizes. Therapeutic management of VVA should follow a sequential order, considering women's age, symptoms, general health as well as treatment preference. Beneficial options include lubricants, moisturizers, vaginal estrogens (estradiol, estriol, promestriene, conjugated estrogens), androgens, prasterone, and laser application. In women with general menopausal symptoms who are candidates for systemic hormone therapy, the lowest effective dose should be used. Oral ospemifene is an effective selective estrogen receptor modulator to treat VVA. Systemic androgens have a limited role. Although laser procedures are commonly used, at this moment the International Society for the Study of Vulvovaginal Disease does not endorse its use out of the setting of clinical trials. Pelvic floor muscle training improves blood flow and elasticity of the vulvovaginal tissue. In breast cancer survivors, moisturizers and lubricants are first line therapy. However, limited absorption of low/ultra-low doses of estrogens suggests safety, especially in women under treatment with aromatase inhibitors. As clinical practice and available preparations vary between countries this text should be adapted to local circumstances.

CONCLUSIONS

There is a wide range of therapeutic options to individualize VVA treatments.

Giant urethral caruncle resembling urethral prolapse causing outflow obstruction

Urethral caruncle is a rare condition primarily affecting elderly. Sometimes, it resembles urethral prolapse or malignancies. It can even cause outflow obstruction or urinary retention. A case of 83-years-old woman with urinary retention since a week prior was presented. Physical examination revealed a bulging mass originating from posterior lip of external urethral meatus. Due to the size, it caused outflow obstruction. The whole mass was excised. Histology examination reported the mass as urethral caruncle. Urethral caruncle is a common problem in elderly which rarely cause outflow obstruction. A thorough examination is required to distinguish it from malignancies and other disorders.

The role of androgens in women's health and wellbeing

Androgens in women, as well as in men, are intrinsic to maintenance of (i) reproductive competency, (ii) cardiac health, (iii) appropriate bone remodeling and mass retention, (iii) muscle tone and mass, and (iv) brain function, in part, through their mitigation of neurodegenerative disease effects. In recognition of the pluripotency of endogenous androgens, exogenous androgens, and selected congeners, have been prescribed off-label for several decades to treat low libido and sexual dysfunction in menopausal women, as well as, to improve physical performance. However, long-term safety and efficacy of androgen administration has yet to be fully elucidated. Side effects often observed include (i) hirsutism, (ii) acne, (iii) deepening of the voice, and (iv) weight gain but are associated most frequently with supra-physiological doses. By contrast, short-term clinical trials suggest that the use of low-dose testosterone therapy in women appears to be effective, safe and economical. There are, however, few clinical studies, which have focused on effects of androgen therapy on pre- and post-menopausal women; moreover, androgen mechanisms of action have not yet been thoroughly explained in these subjects. This review considers clinical effects of androgens on women's health in order to prevent chronic diseases and reduce cancer risk in gynecological tissues.

Intravaginal 6.5 mg prasterone administration in postmenopausal women with overactive bladder syndrome: A pilot study

OBJECTIVE

The aim of this study was to evaluate the impact of vaginally prasterone administration on postmenopausal women with genitourinary syndrome of menopause (GSM) affected by overactive bladder syndrome (OAB). A secondary aim of this study was to assess the efficacy of prasterone on VVA and quality of life (QoL).

STUDY DESIGN

Thirty-two postmenopausal women with GSM and referred OAB symptoms received treatment with daily intravaginal prasterone 6.5 mg. We assessed urinary symptoms through approved ICIQ-OAB and ICIQ-UI questionnaires on incontinence. Women were also screened by the Vaginal Health Index (VHI) to investigate the vulvovaginal atrophy (VVA). Quality of life (QoL) was assessed by the SF-12 Health Survey. Each questionnaire was administrated at baseline (T0) and after a 12-week treatment (T1).

RESULTS

Incontinence questionnaires showed improvement at T1 (from 7.8 ± 2.7 to 2.7 ± 2.2, p < 0.001). Even if women referred an improvement of daily urine although the women reported improvement in daily urine leaks, their urine leak amount did not improve statistically significant [T0 (28.6%) Vs T1 (14.3%), p < 0.16]. Prasterone therapy improved significantly the VHI [T1(21 ± 3.7) Vs T0 (10.8 ± 4.1), p < 0.001]. Finally, women had a statistically significant improvement both in Mental [T1(49.9 ± 11.2) Vs T0 (42 ± 9.2), p < 0.009],) and Physical Health [T1(47.1 ± 9.1) Vs T0 (38.6 ± 8.4), p < 0.006], domains of the SF-12 questionnaire. No women referred side effects.

CONCLUSION

Prasterone is an inactive precursor converted into estrogens and androgens into vaginal tissue. It leads to positive effects on VVA through the activation of the vaginal androgen and estrogen receptors. Empirical evidence in this study suggests that intravaginal 6.5 mg prasterone administration could be an effective treatment for postmenopausal women with GMS affected by OAB.

Pharmacotherapeutic options for the treatment of menopausal symptoms

Introduction: Menopausal symptoms can be very overwhelming for women. Over the years, many pharmacotherapeutic options have been tested, and others are still being developed. Hormone therapy (HT) is the most efficient therapy for managing vasomotor symptoms and related disturbances. The term HT comprises estrogens and progestogens, androgens, tibolone, the tissue-selective estrogen complex (TSEC), a combination of bazedoxifene and conjugated estrogens, and the selective estrogen receptor modulators, such as ospemifene. Estrogens and progestogens and androgens may differ significantly for chemical structure and can be delivered through different routes, thereby displaying various pharmacological and clinical properties. Tibolone, TSEC and SERM also exhibit unique pharmacodynamics that can be exploited to obtain distinctive therapeutic effects. Non-hormonal options fall mainly into the selective serotonin reuptake inhibitor (SSRI) and selective noradrenergic reuptake inhibitor (SNRI), GABA-analogue drug classes.Areas covered: Herein, the authors describe the pharmacokinetics and pharmacodynamics of hormonal (androgens, estrogens, progestogens, tibolone, TSEC, SERMs) and non-hormonal (SSRIs, SNRIs, Gabapentin, Pregabalin, Oxybutynin, Neurokinin antagonists) treatments for menopausal symptoms and report essential clinical trial data in humans.Expert opinion: Patient tailoring of treatment is key to managing symptoms of menopause. Physicians must have in-depth knowledge of the pharmacology of compounds to tailor therapy to the individual patient's characteristics and needs.

International Society for the Study of Women's Sexual Health Clinical Practice Guideline for the Use of Systemic Testosterone for Hypoactive Sexual Desire Disorder in Women

AIM

To provide a clinical practice guideline for the use of testosterone including identification of patients, laboratory testing, dosing, post-treatment monitoring, and follow-up care in women with hypoactive sexual desire disorder (HSDD).

METHODS

The International Society for the Study of Women's Sexual Health appointed a multidisciplinary panel of experts who performed a literature review of original research, meta-analyses, review papers, and consensus guidelines regarding testosterone use in women. Consensus was reached using a modified Delphi method.

OUTCOMES

A clinically useful guideline following a biopsychosocial assessment and treatment approach for the safe and efficacious use of testosterone in women with HSDD was developed including measurement, indications, formulations, prescribing, dosing, monitoring, and follow-up.

RESULTS

Although the Global Position Statement endorses testosterone therapy for only postmenopausal women, limited data also support the use in late reproductive age premenopausal women, consistent with the International Society for the Study of Women's Sexual Health Process of Care for the Management of HSDD. Systemic transdermal testosterone is recommended for women with HSDD not primarily related to modifiable factors or comorbidities such as relationship or mental health problems. Current available research supports a moderate therapeutic benefit. Safety data show no serious adverse events with physiologic testosterone use, but long-term safety has not been established. Before initiation of therapy, clinicians should provide an informed consent. Shared decision-making involves a comprehensive discussion of off-label use, as well as benefits and risks. A total testosterone level should not be used to diagnose HSDD, but as a baseline for monitoring. Government-approved transdermal male formulations can be used cautiously with dosing appropriate for women. Patients should be assessed for signs of androgen excess and total testosterone levels monitored to maintain concentrations in the physiologic premenopausal range. Compounded products cannot be recommended because of the lack of efficacy and safety data.

CLINICAL IMPLICATIONS

This clinical practice guideline provides standards for safely prescribing testosterone to women with HSDD, including identification of appropriate patients, dosing, and monitoring.

STRENGTHS AND LIMITATIONS

This evidence-based guideline builds on a recently published comprehensive meta-analysis and the Global Position Statement endorsed by numerous societies. The limitation is that testosterone therapy is not approved for women by most regulatory agencies, thereby making prescribing and proper dosing challenging.

CONCLUSION

Despite substantial evidence regarding safety, efficacy, and clinical use, access to testosterone therapy for the treatment of HSDD in women remains a significant unmet need.

Prevalence and factors related to urinary incontinence in older adults women worldwide: a comprehensive systematic review and meta-analysis of observational studies

Background

Urinary incontinence is a common condition in the general population and, in particular, the older adults population, which reduces the quality of life of these people, so this study aims to systematically examine and meta-analyse the overall prevalence of urinary incontinence in older women around the world and the related and influential factors.

Methods

This report is a comprehensive systematic review and meta-analysis of the findings of research on urinary incontinence in older adults people across the world through looking for MEDLINE, Cochrane Library Sciencedirect, Embase, Scopus, ProQuest and Persian databases, namely iranmedex, magiran, and SID from January 2000 to April 2020, the heterogeneity of the experiments was measured using the I² index and the data processing was done in the Systematic Meta-Analysis programme.

Results

In 29 studies and the sample size of 518,465 people in the age range of 55–106 years, urinary incontinence in older adults’ women in the world based on a meta-analysis of 37.1% (95% CI: 29.6–45.4%) was obtained. The highest prevalence of urinary incontinence was reported in older adults’ women in Asia with 45.1% (95% CI: 36.9–53.5%). Meta-regression also showed that with increasing the sample size and year of the study, the overall prevalence of urinary incontinence in the older adults women of the world decreased and increased, respectively, which were statistically significant differences (P <  0.05). According to studies, the most important factors influencing the incidence of urinary incontinence in older women are women’s age (p <  0.001), obesity (p <  0.001), diabetes (p <  0.001), women’s education (p <  0.001), delivery rank (p <  0.001), hypertension (p <  0.001), smoking (p <  0.001). They also have urinary tract infections (p <  0.001).

Conclusion

Given the high prevalence of urinary incontinence in older women around the world, health policy makers must consider control and diagnostic measures in older women and prioritize treatment and rehabilitation activities.

The effect of regular resistance exercise, vitamin D, and calcium supplements on the gastrocnemius muscle in rats in the post-menopausal period: An experimental study

Background

Menopause is the natural termination of menstruation which affects the quality and important aspects of women's life.

Objective

To evaluate the effect of regular resistance training (Ex) with vitamin D (Vit. D) and calcium (Ca) supplements in the postmenopausal period on muscle tissue in rats.

Materials and Methods

In this experimental study, 72 female Wistar rats (8-10-wk old) were randomly divided into control, placebo, Vit. D, Ca, Ex, Ca + Vit. D, Ex + Ca, Ex + Vit. D, and Ex + Ca + Vit. D groups. Control and placebo groups were fed with a standard diet and sesame oil, respectively. Two month after the ovariectomy, Ex, Ca (35 mg/kg), and Vit. D (10000 IU) were administred in all groups except the control. The number of muscle and inflammatory cells, fiber diameter, endomysium thickness, and degenerative collagen fiber area were assessed through hematoxylin-eosin staining.

Results

Muscle cell number was increased in the Ex + Vit. D + Ca, Vit. D + Ex, and Vit. D groups compared to the control group; also, inflammatory cell number showed significant increase in the Ex + Vit. D + Ca (12 ± 5.46), Vit. D + Ex (14 ± 3.25), Ex (13 ± 4.08), Vit. D (11 ± 3.26), Ca + Vit. D (10 ± 1.01), and Ca + Ex (9 ± 2.87) groups. Muscle fiber diameter in the Ex + Vit. D + Ca and Vit. D + Ex groups was higher than the other groups. Endomysium thickness was significantly decreased in the Ex + Vit. D + Ca and Vit. D + Ex groups compared to the control and placebo groups (p < 0.001). Degenerative collagen fiber area showed a significant increase in the Ex + Vit. D + Ca and Vit. D + Ex groups (p ≤ 0.001) comparison with the control group.

Conclusion

Regular resistance exercise, Vit. D, and Ca supplements can improve muscle morphological features in the postmenopausal period.

The therapeutic effect of dehydroepiandrosterone (DHEA) on vulvovaginal atrophy

Vulvovaginal atrophy (VVA) is a chronic disease that mostly occurs in postmenopausal women. After menopause, insufficient sex hormones affect the anatomy of the vagina and cause drastic physiological changes. The main histopathological studies of VVA show that postmenopausal estrogen deficiency can lead to the increase of intermediate/parabasal cells, resulting in the loss of lactobacillus, elasticity and lubricity, vaginal epithelial atrophy, pain, dryness. Although the role of estrogen hormones in the treatment of VVA has always been in the past, it is now widely accepted that it also depends on androgens. Estrogen drugs have many side effects. So, Dehydroepiandrosterone（DHEA）is promising for the treatment of VVA, especially when women with contraindications to estrogen have symptoms. This review is expected to understand the latest developments in VVA and the efficacy of DHEA.

Insight on the Intracrinology of Menopause: Androgen Production within the Human Vagina

In this study, we investigated steroidogenic gene mRNA expression in human vaginas and verified the ability of human vagina smooth muscle cells (hvSMCs) to synthesize androgens from upstream precursor dehydroepiandrosterone (DHEA). As a readout for androgen receptor (AR) activation, we evaluated the mRNA expression of various androgen-dependent markers. hvSMCs were isolated from vagina tissues of women undergoing surgery for benign gynecological diseases. In these cells, we evaluated mRNA expression of several steroidogenic enzymes and sex steroid receptors using real time reverse transcription-polymerase chain reaction. Androgen production was quantified with liquid chromatography tandem-mass spectrometry (LC-MS/MS). In vaginal tissues, AR mRNA was significantly less expressed than estrogen receptor α, whereas in hvSMCs, its mRNA expression was higher than progestin and both estrogen receptors. In hvSMCs and in vaginal tissue, when compared to ovaries, the mRNA expression of proandrogenic steroidogenic enzymes (HSD3β1/β2, HSD17β3/β5), along with 5α-reductase isoforms and sulfotransferase, resulted as being more abundant. In addition, enzymes involved in androgen inactivation were less expressed than in the ovaries. The LC-MS/MS analysis revealed that, in hvSMCs, short-term DHEA supplementation increased Δ4-androstenedione levels in spent medium, while increasing testosterone and DHT secretion after longer incubation. Finally, androgenic signaling activation was evaluated through AR-dependent marker mRNA expression, after DHEA and T stimulation. This study confirmed that the human vagina is an androgen-target organ with the ability to synthesize androgens, thus providing support for the use of androgens for local symptoms of genitourinary syndrome in menopause.

Changes of androgens levels in menopausal women

Androgens play an important role in women’s health. They are responsible for the sexual well-being and for maintaining proper structure and function of genitourinary woman’s tract. In menopausal period a relative increase in androgens level is observed as a result of dramatic demise of estrogens and increase of sex hormone-binding globulin (SHBG). However, the response of target tissue depends on its ability to control androgens availability. In menopausal women the symptoms of both hyperandrogenemia and of androgens deficiency may be observed. Hyperandrogenemia may result in discrete symptoms, such as slight terminal facial hair grow, or worsening of scalp hair loss. Those symptoms should not be belittled in any of the cases, especially when their severity increases one should seek possible causes of postmenopausal hyperandrogenemia.

Ovarian and adrenal aging, leading to a progressive decline in androgen levels, may exert detrimental effects on the quality of life. During menopause, changes in activation of particular brain spheres are connected with low sex hormone concentration and correlate with loss of sexual arousability. Hypoactive sexual desire dysfunction (HSDD) may be the direct result of androgens deficiency in menopausal women. It is the only evidence-based indication for the use of testosterone in women. However, before treatment, other diseases must be excluded that might alternatively be the cause of HSDD.

Vaginal pH as a Diagnostic Tool for Menopause: A Preliminary Analysis

Introduction

Menopause is defined as the permanent cessation of menstruation, as a result of decrease in ovarian follicles and the loss of ovarian activity. There is decrease in inhibin B level which causes decrease in negative feedback on the serum follicle-stimulating hormone (FSH), which in turn increases the level of serum FSH. Serum FSH is routinely used as a marker of menopause. Decline in the estrogen level causes thinning of vaginal epithelium, resulting in less exfoliation of the vaginal epithelial cells, lesser available glycogen, and decreased substrate for acid production, leading to increase in vaginal pH.

Aims

The aim of this study is to compare the sensitivity of vaginal pH versus serum FSH level to diagnose menopause.

Settings and Design

This is a cross-sectional study, performed in obstetrics and gynecology outpatient department of a teaching hospital of central Gujarat.

Subjects and Methods

A total of 120 women who had their last menstrual period >1 year back (menopause) were included in the study. Vaginal pH was measured and serum sample was taken to measure FSH level. Sensitivity of both vaginal pH and serum FSH to diagnose menopause was compared. McNemar test was used to analyze the convergence of the two methods for the diagnosis of menopause.

Results

In the absence of vaginal infection, sensitivity of vaginal pH to diagnose menopause was 90%, while sensitivity of the serum FSH was 85%.

Conclusions

Sensitivity of the vaginal pH is similar to the serum FSH for diagnosis of menopause.

Updates on Therapeutic Alternatives for Genitourinary Syndrome of Menopause: Hormonal and Non-Hormonal Managements

Postmenopausal atrophic vaginitis, along with vasomotor symptoms and sleep disorders, is one of the most troublesome symptoms of menopause. However, many women do not manage this symptom properly due to insufficient knowledge of the symptoms or sexual embarrassment. With appropriate treatment, many postmenopausal women can experience relief from discomforts, including burning sensation or dryness of the vagina and dyspareunia. Topical lubricants and moisturizers, systemic and local estrogens, testosterones, intravaginal dehydroepiandrosterones (DHEAs), selective estrogen receptor modulators, and energy-based therapies are possible treatment modalities. Systemic and local estrogen therapies effectively treat genitourinary syndrome of menopause (GSM), but they are contraindicated in patients with breast cancer, for whom lubricants and moisturizers must be considered as the primary treatment. Intravaginal DHEA and ospemifene can be recommended for moderate to severe GSM; however, there is insufficient data on the use of intravaginal DHEA or ospemifene in patients with breast cancer, and further studies are needed. Energy-based devices such as vaginal laser therapy reportedly alleviate GSM symptoms; however, the U.S. Food and Drug Administration warning has recently been issued because of complications such as chronic pain and burning sensations of the vagina. To summarize, clinicians should provide appropriate individualized treatment options depending on women's past history, symptom severity, and chief complaints.

The Expression of Hormone Receptors as a Gateway toward Understanding Endocrine Actions in Female Pelvic Floor Muscles

OBJECTIVE

To provide an overview of the hormone actions and receptors expressed in the female pelvic floor muscles, relevant for understanding the pelvic floor disorders.

METHODS

We performed a literature review focused on the expression of hormone receptors mainly in the pelvic floor muscles of women and female rats and rabbits.

RESULTS

The impairment of the pelvic floor muscles can lead to the onset of pelvic floor dysfunctions, including stress urinary incontinence in women. Hormone milieu is associated with the structure and function alterations of pelvic floor muscles, a notion supported by the fact that these muscles express different hormone receptors. Nuclear receptors, such as steroid receptors, are up till now the most investigated. The present review accounts for the limited studies conducted to elucidate the expression of hormone receptors in pelvic floor muscles in females.

CONCLUSION

Hormone receptor expression is the cornerstone in some hormone-based therapies, which require further detailed studies on the distribution of receptors in particular pelvic floor muscles, as well as their association with muscle effectors, involved in the alterations relevant for understanding pelvic floor disorders.

Reduced concentrations of vaginal metabolites involved in steroid hormone biosynthesis are associated with increased vulvar vestibular pain and vaginal muscle tenderness in provoked vestibulodynia: An exploratory metabolomics study

Provoked vestibulodynia (PVD) is a chronic vulvar pain disorder characterized by hypersensitivity and severe pain with pressure localized to the vulvar vestibule. Knowledge regarding pathophysiological mechanisms contributing to the etiology and production of symptoms in PVD remains incomplete but is considered multifactorial. Using a cross-sectional observational study design, data from untargeted metabolomic profiling of vaginal fluid and plasma in women with PVD and healthy women was combined with pain testing and brain imaging in women with PVD to test the hypotheses that women with PVD compared to healthy women show differences in vaginal and plasma metabolites involved in steroid hormone biosynthesis. Steroid hormone metabolites showing group differences were correlated with vulvar vestibular pain and vaginal muscle tenderness and functional connectivity of brain regions involved in pain processing in women with PVD to provide insight into the functional mechanisms linked to the identified alterations. Sensitivity analyses were also performed to determine the impact of hormonal contraceptive use on the study findings. Women with PVD compared to healthy controls had significant reductions primarily in vaginal fluid concentrations of androgenic, pregnenolone and progestin metabolites involved in steroidogenesis, suggesting localized rather than systemic effects in vagina and vulvar vestibule. The observed reductions in androgenic metabolite levels showed large effect size associations with increased vulvar vestibular pain and vulvar muscle tenderness and decreases in androgenic and progestin metabolites were associated with decreased connectivity strength in primary sensorimotor cortices. Women with PVD showed symptom-associated reductions in vaginal fluid concentrations of metabolites involved in the biosynthesis of steroid hormones previously shown to affect the integrity of vulvar and vaginal tissue and nociceptive processing. Deficiency of certain steroids may be an important mechanism contributing to the pathophysiology of symptoms in PVD may provide potential diagnostic markers that could lead to new targets for therapeutic intervention.

Sexual behaviors and function during menopausal transition-does menopausal hormonal therapy play a role?

OBJECTIVES

The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an "end all" in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors.

METHODS

A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls-MHT non-users (n = 103). Diagnostic and Statistical Manual of Mental Disorders -five criteria were used to assess sexual dysfunction. Sexual problems were evaluated by the Changes in Sexual Function Questionnaire (CSFQ), body image by Body Exposure during Sexual Activity Questionnaire, and quality of relationship by the Well-Match Relationship Questionnaire. Logistic regression was used to determine the risk factors for FSD and sexual problems.

RESULTS

Women using MHT had higher body esteem during sexual activities, better sexual function (CSFQ) in all domains except desire/interest, better quality of relationship, and lower prevalence of FSD and sexual complaints (CSFQ) except arousal/excitement problems. However, self-rated effects of MHT on sexual behaviors showed that MHT did not play a major role. Women with secondary and higher education (OR = 0.09, CI: 0.02-0.4; P < 0.01 and OR = 0.2, CI: 0.05-1.0; P < 0.05, respectively) and with a higher number of lifetime sexual partners (OR = 0.6, CI: 0.4-0.9; P < 0.01) were less likely to have FSD. In contrast, individuals with more anxious behaviors during sexual activity (OR = 3.2, CI: 1.3-7.3; P < 0.01) and with more severe menopausal symptoms (OR = 1.1, CI: 1.0-1.2; P < 0.001) were more likely to have FSD. Using MHT was not associated with that risk nor with sexual function.

CONCLUSION

In women during menopausal transition, sexual behaviors were different in MHT users compared with non-users. However, in this cross-sectional observational study conducted in 210 women between the ages of 45 to 55 years, using MHT was not associated with modification of sexual function, decreasing the risk of sexual dysfunction, nor sexual problems.

Postmenopausal Hormone Therapy-Local and Systemic: A Pharmacologic Perspective

Every woman, if she lives long enough, will transition into menopause, and as the US population ages, women will be spending more time in a postmenopausal state than before. For postmenopausal women, the decision to initiate menopausal hormone therapy should be individualized. A thorough evaluation of the patient's cardiovascular, venous thromboembolic, cancer, and fracture risk should be considered along with the woman's quality of life. Hormone therapy exerts its therapeutic effects on vasomotor symptoms, the skeleton, and the genitourinary system independent of age since menopause and these benefits are lost once hormone therapy is stopped. Here we review the pharmacologic properties dose, formulation, mode of administration, timing of initiation, and duration of hormonal therapies in regard to optimizing benefit and minimizing risk to the patient. This discussion will focus on the effects of common hormonal therapies including estrogen (local and systemic), progesterone, estrogen receptor agonist/antagonist, and local dehydroepiandrosterone and include a brief review of compounded bioidentical hormone therapy.

Effect of flaxseed oil on biochemical parameters, hormonal indexes and stereological changes in ovariectomized rats

The ovariectomized rat is a widely used preclinical model for studying postmenopausal and its complications. In this study, the therapeutic effect of flaxseed oil on the ovariectomized adult rats was investigated. Our results showed that biochemical parameters including calcium, oestrogen and progesterone levels increase 8 weeks after ovariectomy in rats. Also, the amount of alkaline phosphatase decreased significantly after 8 weeks compared with the OVX rat. The healing potential of flaxseed oil was proven by successfully recovering the affected tissue and preventing the unpleasant symptoms of ovariectomized rats. The biological effects of flaxseed oil may be due to high amounts of fatty acids, phytoestrogens and an array of antioxidants. The results suggest that flaxseed oil can mimic the action of oestrogen and can be a potential treatment for hormone replacement therapy (HRT).

The effect of pathophysiological changes in the vaginal milieu on the signs and symptoms of genitourinary syndrome of menopause (GSM)

IMPORTANCE AND OBJECTIVE

The aim of this study was to provide an overview of the most recent literature on genitourinary syndrome of menopause (GSM), to explore the key elements of GSM diagnosis, and the potential impact of pathophysiological changes in the vaginal milieu on vulvovaginal symptoms.

METHODS

The MEDLINE database was searched, and only articles written in English were considered. Additional references were identified by hand searching the bibliographies of the included articles.

DISCUSSIONS AND CONCLUSION

The vaginal milieu plays important roles in producing bothersome symptoms in the host. In women with GSM, low hormone states can result in pathophysiological changes in the vaginal milieu, including the vaginal microbiome and the mucosal immunity. Hormone-associated disruption of the balance of the indigenous microbiota and the dysregulation of these immune responses are the pathophysiological basis of GSM symptoms. However, whether the microbiome and mucosal immunity are markers of vulvovaginal disorder or agents actively promoting a healthy vagina are still not fully understood. It is an important area of focus.

Hormonal profile of menopausal women receiving androgen replacement therapy: a meta-analysis

PURPOSE

Ovarian and adrenal aging leads to a progressive decline in androgen levels and deleterious effects on the quality of life. Despite this, specific replacement is not routinely recommended in the management of women with a physiological or pathological decline in their production, mainly due to the lack of long-term follow-up safety data. The purpose of this paper was to meta-analyze and summarize the existing data about hormonal profile changes in menopausal women receiving androgen replacement treatments. Full-text articles published through May 30, 2018 were found via MEDLINE and Embase and selected according to the strict inclusion criteria.

METHODS

Randomized clinical trials and case-control studies were enrolled. Studies not reporting steroid serum levels or not providing a control group were excluded from the analysis. Studies enrolling women with genetic defects or severe chronic systemic diseases were excluded. 113 papers fulfilled the inclusion criteria and 56 papers were included in the analysis. Desired data were compiled and extracted by independent observers.

RESULTS

Androgen administration increases E1, E2, testosterone, DHEA and DHEAS serum levels, and reduces SHBG. However, the E1 and E2 increase is evident only when DHEA is administered.

CONCLUSIONS

Whatever androgen formulation we choose in postmenopausal women, the end result is a rise in testosterone serum levels. However, DHEA regimen is also associated with an increased estrogenic availability. This might be crucial when choosing the best possible treatment for each patient individually taking into consideration if potential benefits outweigh the risks.
