Maturitas 2024; 186:108006. [PMID: 38704313 DOI: 10.1016/j.maturitas.2024.108006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 04/15/2024] [Accepted: 04/19/2024] [Indexed: 05/06/2024]
Abstract
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.

Abstract
INTRODUCTION Hyperandrogenism and hypoandrogenism are complex disorders involving multiple-organ systems. While androgen excess is a well-characterized condition, androgen deficiency still needs diagnostic criteria, as there are no specific cutoffs. AREAS COVERED We highlight the most recent findings on the role of androgens in female pathophysiology, investigating clinically relevant conditions of androgen insufficiency or excess throughout a woman's life, and their possible therapeutic management. EXPERT OPINION Combined oral contraceptives (COCs) should be considered as first-line therapy for the management of menstrual irregularity and/or clinical hyperandrogenism in adolescents with a clear diagnosis of polycystic ovary syndrome (PCOS). There are limited evidence-based data regarding specific types or doses of COCs for management of PCOS in women; however, the lowest effective estrogen dose should be considered for treatment. Despite evidence regarding safety, efficacy, and clinical use, testosterone therapy has not been approved for women by most regulatory agencies for treatment of hypoactive sexual desire disorder (HSDD). The long-term safety for treatments with testosterone is still to be evaluated, and this review highlights the need for more research in this area.

Abstract
Androgens play a key biological role in libido and sexual arousal in women, and knowledge about their complex role in other systems remains ambiguous and incomplete. This narrative review examines the role of endogenous androgens in women's health throughout the life span before focusing on evidence surrounding the use of androgen-based therapies to treat postmenopausal women. The role of testosterone as a therapeutic agent in women continues to attract controversy as approved preparations are rare, and use of off-label and compounded formulations is widespread. Despite this androgen therapy has been used for decades in oral, injectable, and transdermal formulations. Responses to androgen therapy have been demonstrated to improve aspects of female sexual dysfunction, notably hypoactive sexual desire disorder, in a dose related manner. Substantial research has also been conducted into the role of androgens in treating aspects of the genitourinary syndrome of menopause (GSM). Evidence for benefits beyond these is mixed and more research is required regarding long-term safety. However, It remains biologically plausible that androgens will be effective in treating hypoestrogenic symptoms related to menopause, either through direct physiological effects or following aromatization to estradiol throughout the body.

Effects of Gender and Vitamin D on Vascular Reactivity of the Carotid Artery on a Testosterone-Induced PCOS Model. Int J Mol Sci 2023; 24:16577.

Abstract
The negative cardiovascular effects of polycystic ovary syndrome (PCOS) and vitamin D deficiency (VDD) have been discussed previously; however, the sex differences between PCOS females and males are not yet known. Our aim was to investigate the effect of PCOS and VDD in the carotid artery of male and female Wistar rats. Females were treated with transdermal testosterone (Androgel) for 8 weeks, which caused PCOS. VDD and vitamin D supplementation were accomplished via diet. The carotid arteries' contraction and relaxation were examined using myography. Receptor density was investigated using immunohistochemistry. In PCOS females, angiotensin receptor density, angiotensin II-induced contraction, androgen receptor optical density, and testosterone-induced relaxation increased. The increased contractile response may increase cardiovascular vulnerability in women with PCOS. As an effect of VDD, estrogen receptor density increased in all our groups, which probably compensated for the reduced relaxation caused by VDD. Testosterone-induced relaxation was decreased as a result of VDD in males and non-PCOS females, whereas this reduction was absent in PCOS females. Male sex is associated with increased contraction ability compared with non-PCOS and PCOS females. VDD and Androgel treatment show significant gender differences in their effects on carotid artery reactivity. Both VDD and PCOS result in a dysfunctional vascular response, which can contribute to cardiovascular diseases.

Abstract
Menopause is the cessation of ovarian function, with loss of reproductive hormone production and irreversible loss of fertility. It is a natural part of reproductive aging. The physiology of the menopause is complex and incompletely understood. Globally, menopause occurs around the age of 49 years, with geographic and ethnic variation. The hormonal changes of the menopause transition may result in both symptoms and long-term systemic effects, predominantly adverse effects on cardiometabolic and musculoskeletal health. The most effective treatment for bothersome menopausal symptoms is evidence-based, menopausal hormone therapy (MHT), which reduces bone loss and may have cardiometabolic benefits. Evidence-based non-hormonal interventions are also available for symptom relief. Treatment should be individualized with shared decision-making. Most MHT regimens are not regulator approved for perimenopausal women. Studies that include perimenopausal women are needed to determine the efficacy and safety of treatment options. Further research is crucial to improve menopause care, along with research to guide policy and clinical practice.

Abstract
OBJECTIVES We aimed to better understand the histologic changes in vaginectomy specimens in transgender and gender-diverse (TGD) individuals after prolonged androgen administration. METHODS After obtaining institutional review board approval, we reviewed clinical records for all TGD individuals who underwent vaginal tissue resection at our institution between January 2002 and July 2020. RESULTS Ten transgender males who underwent vaginectomy for gender affirmation were identified. All patients had been assigned female gender at birth, and the median age at surgery was 41 years (range, 22-74 years). All 10 patients had received androgen for 2 to 10 years preoperatively. The corresponding pathology specimens were examined grossly and microscopically, including with immunohistochemical stains for NKX3.1, prostate-specific antigen (PSA), p501s, and androgen receptor (AR). No gross lesions were identified. Microscopically, prostate-like glands (8/10), urothelial metaplasia (4/10), and vaginal atrophy (8/10) were identified. Seven cases with prostate-like glands showed positive staining with PSA, NKX3.1, p501s, and AR in both squamous and glandular components. CONCLUSIONS Recognition of these androgen-related changes enables pathologist to avoid the overdiagnosis of dysplasia. Long-term follow-up is needed to thoroughly understand any potential future implications of these androgen-related changes.

Abstract
Every woman who lives past midlife will experience menopause, which, by definition, is complete cessation of ovarian function. This process might occur spontaneously (natural menopause) or be iatrogenic (secondary menopause), and can be further classified as 'early' if it occurs before the age of 45 years and 'premature' if it occurs before the age of 40 years. Globally, the mean age of natural menopause is 48.8 years, with remarkably little geographic variation. A woman's age at menopause influences health outcomes in later life. Early menopause is associated with a reduced risk of breast cancer, but increased risks of premature osteoporosis, cardiovascular disease and premature death. The cardinal symptoms of menopause, and adverse health sequelae, are due to loss of ovarian oestrogen production. Consequently, menopausal hormone therapy (MHT) that includes oestrogen or an oestrogenic compound ameliorates menopausal symptoms, while preventing menopause-associated bone loss and cardiometabolic changes. Importantly, comprehensive care of postmenopausal women involves lifestyle optimization (attention to nutrition and physical activity, reducing alcohol consumption and not smoking) and treating other established chronic disease risk factors. This Review offers a commentary specifically on the contemporary use of MHT and novel pharmaceutical alternatives to manage menopausal symptoms.

Abstract
Genitourinary syndrome of menopause (GSM) is a term used to define a compilation of signs and symptoms arising from decreased estrogenic stimulation of the vulvovaginal and lower urinary tract. Among 27–84% of women in postmenopausal are affected for symptoms of GSM, and these can unquestionably impair health, sexual function, consequently the quality of life of these women. The main signs and symptoms of GSM include, among others, burning, irritation, vulvovaginal dryness, dyspareunia, urinary symptoms of urgency, dysuria, or recurrent urinary tract infection. The diagnosis can be made through anamnesis, questionnaires, physical exams, and, sometimes, complementary exams. Objective vaginal assessment is essential and can be complemented by using the Vaginal Health Index (VHI), Vaginal Maturation Index (VMI), or vaginal pH measurement. The acknowledgment of this condition by health professionals is crucial for its identification and proper management and exclusion of other conditions that make a differential diagnosis with it.

Abstract
This study aimed to explore the effect of pelvic reconstruction surgery on the relation of pelvic organ prolapse (POP) and overactive bladder (OAB) and the impact of preoperative vaginal oestrogen supplement on vaginal tissue. A total of 100 postmenopausal women with symptomatic POP who underwent pelvic reconstruction surgery (laparoscopic sacrocolpopexy or transvaginal mesh) were enrolled in this study. Preoperative vaginal oestrogen was prescribed in 28 cases. The evaluation tools consisted of POP-Q, urodynamic study, Overactive Bladder Symptom Score (OABSS), and urinary NGF. Vaginal maturation index and vaginal specimens for hormone receptors study were investigated during operation to evaluate the effect of topical oestrogen. Follow-up assessments were performed at 1, 3, and 6 months after surgery. Preoperatively, 58 (58%) were POP with OAB. After reconstruction surgery, the OABSS decreased significantly (6.87 ± 0.85 vs 3.77 ± 0.61, p < 0.001) at postoperative 6 months in the group. Remarkable increasing trends of urinary NGF levels are noted till 3 months postoperatively, then decreasing to the baseline level at 6 months postoperative follow-up. Remarkable decrease of mRNA of the androgen receptor and significant higher expression of progesterone receptor (PR) were noted after use of the vaginal oestrogen cream. The severity of OAB in the POP women shows moderate degree according to OABSS. Pelvic reconstruction surgery can significantly improve the OAB symptoms. The surgery induced inflammation effect lasts for about 6 months. Short-term preoperative supplement of topical oestrogen brings alterations of the vaginal epithelium.

Abstract
CONTEXT.— Transgender men and transmasculine persons experience a discordance between the female sex they were assigned at birth and their gender. They may choose to take hormone therapy and/or undergo surgery to masculinize the body. Understanding the common (and less common) histologic changes present in patients taking masculinizing hormones will empower pathologists to better serve this unique patient population. OBJECTIVE.— To summarize histologic findings in surgical pathology specimens from persons taking masculinizing hormones as a part of gender transition. DATA SOURCES.— A systematic review of the OVID Medline and PubMed databases was performed to identify all studies describing histologic findings in surgical pathology specimens from transgender men from January 1946 to January 2021. CONCLUSIONS.— Publication in this area has markedly increased in the last 2 decades. However, most of the studies identified were descriptive and case reports describing changes seen in specimens removed as a part of masculinizing surgical procedures. Benign histologic findings include stromal hyalinization and epithelial atrophy in the breast, polycystic ovarian syndrome-like changes in the ovary, and transitional cell metaplasia in the cervix. The most commonly reported neoplastic finding was adenocarcinoma of the breast, with rare cases of ovarian, endometrial, cervical, vaginal, pituitary, pancreatic, and cardiovascular neoplasia also reported. Ongoing research in this area is needed to better characterize the histologic findings in persons taking masculinizing hormones to provide a deeper understanding of the effect of these treatments on different tissues and facilitate better patient management.

Abstract
Background: Despite the lack of approved testosterone formulations for women in most countries, testosterone therapy is still being offered to women worldwide. Aging and loss of ovarian or adrenal function, among others, can lower testosterone levels in women. However, international guidelines currently do not routinely recommend androgen replacement therapy due to lack of long-term safety data. Evidence on its benefits and risks still remains uncertain. Objectives: The aim of this literature review is to present current studies and guidelines that examined the effects of testosterone therapy for postmenopausal women, including its role on cognition and mood; breast and endometrial cancer risks; musculoskeletal, cardiovascular, and genitourinary health; and sexual function. Methodology: A review of literature was done using PubMed, EMBASE, Science Direct, OVID, and Google scholar, with the following key words: androgen, testosterone, menopause, and hypoactive sexual desire dysfunction. We identified reviews, clinical trials, and guidelines. The population was limited to postmenopausal women. Results: There is no evidence from current published literature to support the use of testosterone therapy for female well-being, mood and cognition, bone and cardiovascular health. Intravaginal testosterone appears to be a promising alternative for the treatment of genitourinary symptoms of menopause (GSM) but efficacy and safety are yet to be confirmed. Well-designed, randomized, and placebo-controlled trials are needed to establish long-term safety, efficacy, and appropriate dosing and route of testosterone therapy in postmenopausal women. The only evidence-based indication for testosterone therapy in women is for the treatment of postmenopausal hypoactive sexual desire disorder (HSDD). Should a trial of testosterone therapy be given for HSDD, the transdermal route is the preferred method of delivery. Baseline total testosterone concentration should be determined before starting treatment, and repeated after 3–6 months. Serum testosterone levels should be monitored at regular intervals to avoid supraphysiologic dosing. Conclusion: Currently, there is no robust evidence to support the use of exogenous testosterone to improve female well-being, musculoskeletal health, mood and cognition, as well as bone and cardiovascular health among postmenopausal women. The only evidence-based indication for testosterone therapy in women is the treatment of postmenopausal hypoactive sexual desire disorder, but only after all other causes of sexual dysfunction have been ruled out. To date, testosterone therapy has no US Food and Drug Administration (US FDA) approval due to the lack of long-term efficacy and safety data.

Abstract
The role of testosterone in women and its potential as a therapeutic agent continue to attract controversy. The clinical trials of testosterone therapy for women primarily have focused on treatment of female sexual dysfunction, with the largest placebo-controlled studies being of transdermal testosterone in postmenopausal women. Based on the cumulative data from these studies, loss of sexual desire with associated personal distress currently is the only agreed-on indication for judicious testosterone supplementation for postmenopausal women. This article reviews the physiology of testosterone in women, summarizes the findings from observational studies and clinical trials, and considers indications for testosterone use.

Abstract
Premature ovarian insufficiency (POI) results in both estrogen and testosterone insufficiency. Whether testosterone therapy may be of benefit for women with POI is uncertain. Presently, the only evidence-based indication for testosterone therapy for women is for the treatment of postmenopausal women with low sexual desire with associated personal distress. Consistent with this, available evidence does not support the prescription of testosterone to prevent cardiometabolic disease, bone loss, sarcopenia, or cognitive decline or to improve well-being and low mood in postmenopausal women. Data pertaining to the treatment of women with POI with testosterone are limited. This article reviews androgen physiology in premenopausal women and the impact of POI on circulating androgen concentrations, summarizes findings from observational studies and clinical trials of testosterone therapy in premenopausal women and women with POI, and concludes with recommendations regarding testosterone use in women with POI.

Abstract
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.

Abstract
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.

Abstract
The physiological, clinical and therapeutic aspects of testosterone in women's health are still a matter of controversy and debate. Quality evidence data of clinical trials favors the use of transdermal testosterone in postmenopausal women with female sexual dysfunction causing distress. Doses of testosterone should approximate physiological testosterone levels found in premenopausal women, avoiding supraphysiological concentrations that expose women to adverse events. Short-term treatment periods have been shown to be effective and safe in postmenopausal women with hypoactive sexual desire disorder/dysfunction. However, long-term safety of testosterone use must be determined.

Abstract
OBJECTIVE The objective of this consensus document is to broaden the perspective on clinical management of genitourinary syndrome of menopause to include androgens. METHODS A modified Delphi method was used to reach consensus among the 14 international panelists representing multiple disciplines and societies. RESULTS Menopause-related genitourinary symptoms affect over 50% of midlife and older women. These symptoms have a marked impact on sexual functioning, daily activities, emotional well-being, body image, and interpersonal relations. Tissues in the genitourinary system are both androgen and estrogen-dependent. The clitoris, vestibule, including minor and major vestibular glands, urethra, anterior vaginal wall, periurethral tissue, and pelvic floor are androgen-responsive. Historically, treatment of postmenopausal genitourinary symptoms involved both androgens and estrogens. This subsequently gave rise to predominantly estrogen-based therapies. More recently, double-blind, placebo-controlled clinical trials have demonstrated that local vaginal dehydroepiandrosterone improves symptoms in postmenopausal women, including moderate to severe dyspareunia. Limited data suggest that systemic testosterone treatment may improve vaginal epithelial health and blood flow. Open-label studies that have used high doses of intravaginal testosterone in the presence of aromatase inhibitor therapy for breast cancer have resulted in supraphysiological serum testosterone levels, and have been reported to lower vaginal pH, improve the vaginal maturation index, and reduce dyspareunia. CONCLUSIONS Vaginal dehydroepiandrosterone, hypothesized to enhance local production of both androgen and estrogen, is effective for the management of dyspareunia in menopause. Vaginal testosterone offers potential as a treatment for genitourinary syndrome of menopause, but more studies are needed.

Abstract
OBJECTIVES Intravaginal testosterone has emerged as a potential treatment for vulvovaginal atrophy (VVA) in women, in general, and women taking an aromatase inhibitor (AI). A systematic review of the literature was undertaken to determine whether available clinical trial data support efficacy and safety of intravaginal testosterone for the treatment of VVA. METHODS Scopus, MEDLINE, EMBASE, and the Cochrane Library databases were systematically searched on July 26, 2017, for human studies published in English of clinical trials of intravaginal testosterone. RESULTS Six separate clinical trials were identified that ranged in size from 10 to 80 participants, with either single dose, or durations of 4 to 12 weeks. Only one study incorporated a double-blind design. Three studies were of women taking an AI.Taken together, the studies suggest that intravaginal testosterone may lower vaginal pH, increase the proportion of vaginal lactobacilli, and possibly improve the vaginal maturation index. The lack of a placebo treatment in four studies, and failure to adjust for baseline differences, resulted in uncertainty of the effect on sexual function. Safety remains uncertain because of the small number of women exposed, short study durations, and inconsistent and incomplete outcome reporting for sex steroid levels. CONCLUSION Adequately powered double-blind, placebo-controlled clinical trials of intravaginal testosterone therapy are needed to establish both efficacy and safety.

Abstract
Background: Sex steroid hormones and their receptors are important in female sexual function. The aim of this study was to investigate the expression and distribution of estrogen receptor (ER)α, ERβ, G-protein-coupled ER-1 (GPER), androgen receptor (AR), progesterone receptor (PR)A, PRB and connective tissue growth factor (CTGF) in the vaginal wall among women who had been treated for cervical cancer with radiotherapy. Material and methods: We included cervical cancer survivors treated with radiotherapy and premenopausal control women of the same age scheduled for benign gynecological surgery. We analyzed the expression and distribution of sex steroid hormone receptors and CTGF in biopsies from the vaginal wall, by real-time PCR and immunohistochemistry (IHC). Serum samples were analyzed for hormone levels and radiation dose at biopsy site were calculated and correlated to levels of the sex steroid hormone receptors. Results: In the cervical cancer survivors (n = 34), we found a lower expression of ERα at both mRNA and protein levels, compared to the control women (n = 37). In the survivors with high radiation dose at biopsy site, the immunostaining of ERα and AR was lower in the epithelium and the stroma, compared to survivors with minimal radiation dose. The later group showed expression of ERα comparable to the control women. The cancer survivors were sufficiently substituted with systemic estradiol with no difference in the serum estradiol levels compared to control women. Conclusions: We found that external radiation reduces the ERα and AR protein expression in the vaginal mucosa, indicating that the vaginal changes in irradiated cervical cancer survivors and the lack of response to hormonal treatment could be due to the decreases in sex steroid hormone receptor expression.

Abstract
Gender-affirming hormonal treatment (HT) in transgender people is considered safe in general, but the question regarding (long-term) risk on sex hormone-related cancer remains. Because the risk on certain types of cancer differs between men and women, and some of these differences are attributed to exposure to sex hormones, the cancer risk may be altered in transgender people receiving HT. Although reliable epidemiologic data are sparse, the available data will be discussed in this article. Furthermore, recommendations for cancer screening and prevention will be discussed as well as whether to withdraw HT at time of a cancer diagnosis.

Abstract
CONTEXT Intravaginal testosterone (IVT) is a potential treatment of vulvovaginal atrophy (VVA) associated with aromatase inhibitor (AI) use. OBJECTIVE To investigate the effects of IVT on sexual satisfaction, vaginal symptoms, and urinary incontinence (UI) associated with AI use. DESIGN Double-blind, randomized, placebo-controlled trial. SETTING Academic clinical research center. PARTICIPANTS Postmenopausal women taking an AI with VVA symptoms. INTERVENTION IVT cream (300 μg per dose) or identical placebo, self-administered daily for 2 weeks and then thrice weekly for 24 weeks. MAIN OUTCOMES AND MEASURES The primary outcome was the change in the sexual satisfaction score on the Female Sexual Function Index (FSFI). Secondary outcomes included vaginal symptoms and responses to the Profile of Female Sexual Function, the Female Sexual Distress Scale-Revised (FSDS-R), and the Questionnaire for UI Diagnosis. Serum sex steroids were measured. RESULTS A total of 44 women were randomly assigned and 37 provided evaluable data, (mean age 56.4 years, SD 8.8 years). At 26 weeks, the mean between-group difference in the baseline-adjusted change in FSFI satisfaction scores was significantly greater for the IVT group than the placebo group (mean difference 0.73 units; 95% CI, 0.02 to 1.43; P = 0.043). IVT cream resulted in significant improvements, compared with placebo, in FSDS-R scores (P = 0.02), sexual concerns (P < 0.001), sexual responsiveness (P < 0.001), vaginal dryness (P = 0.009), and dyspareunia (P = 0.014). Serum sex steroid levels did not change. Few women had UI symptoms, with no treatment effect. CONCLUSION IVT significantly improved sexual satisfaction and reduced dyspareunia in postmenopausal women on AI therapy. The low reporting of UI among women on AI therapy merits further investigation.

Abstract
There is significant interest in the use of androgen therapy for postmenopausal women. This review provides background on endogenous androgens in women, describes factors that affect circulating androgen concentrations, and examines the relationship between low levels of androgens and sexual problems. Possible effects of androgens in postmenopausal women beyond sexual function also are discussed. Clinical trials of androgen therapy for the treatment of hypoactive sexual desire disorder are reviewed, with a discussion of potential risks. A practical approach to using androgens to treat low sexual desire with associated distress is presented, accompanied by an illustrative case.

Abstract
INTRODUCTION Genitourinary conditions in women increase in prevalence with age. Androgens are prerequisite hormones of estrogen biosynthesis, are produced in larger amounts than estrogens in women, and decrease throughout adulthood. However, research and treatment for genitourinary complaints have traditionally focused on estrogens to the exclusion of other potential hormonal influences. AIM To summarize and evaluate the evidence that androgens are important for maintaining genitourinary health in women and that lack of androgenic activity can contribute to the development of symptoms of the genitourinary syndrome of menopause. METHODS The role of androgens in the pathophysiology, diagnosis, and treatment of genitourinary syndrome of menopause was discussed by an international and multidisciplinary panel during a consensus conference organized by the International Society for the Study of Women's Sexual Health. A subgroup further examined publications from the PubMed database, giving preference to clinical studies or to basic science studies in human tissues. MAIN OUTCOME MEASURES Expert opinion evaluating trophic and functional effects of androgens, their differences from estrogenic effects, and regulation of androgen and estrogen receptor expression in female genitourinary tissues. RESULTS Androgen receptors have been detected throughout the genitourinary system using immunohistochemical, western blot, ligand binding, and gene expression analyses. Lower circulating testosterone and estradiol concentrations and various genitourinary conditions have been associated with differential expression of androgen and estrogen receptors. Supplementation of androgen and/or estrogen in postmenopausal women (local administration) or in ovariectomized animals (systemic administration) induces tissue-specific responses that include changes in androgen and estrogen receptor expression, cell growth, mucin production, collagen turnover, increased perfusion, and neurotransmitter synthesis. CONCLUSION Androgens contribute to the maintenance of genitourinary tissue structure and function. The effects of androgens can be distinct from those of estrogens or can complement estrogenic action. Androgen-mediated processes might be involved in the full or partial resolution of genitourinary syndrome of menopause symptoms in women. Traish AM, Vignozzi L, Simon JA, et al.

Abstract
INTRODUCTION Androgens have been implicated as important for female sexual function and dysfunction. AIM To review the role of androgens in the physiology and pathophysiology of female sexual functioning and the evidence for efficacy of androgen therapy for female sexual dysfunction (FSD). METHODS We searched the literature using online databases for studies pertaining to androgens and female sexual function. Major reviews were included and their findings were summarized to avoid replicating their content. MAIN OUTCOME MEASURES Quality of data published in the literature and recommendations were based on the GRADES system. RESULTS The literature supports an important role for androgens in female sexual function. There is no blood androgen level below which women can be classified as having androgen deficiency. Clinical trials have consistently demonstrated that transdermal testosterone (T) therapy improves sexual function and sexual satisfaction in women who have been assessed as having hypoactive sexual desire disorder. The use of T therapy is limited by the lack of approved formulations for women and long-term safety data. Most studies do not support the use of systemic dehydroepiandrosterone therapy for the treatment of FSD in women with normally functioning adrenals or adrenal insufficiency. Studies evaluating the efficacy and safety of vaginal testosterone and dehydroepiandrosterone for the treatment of vulvovaginal atrophy are ongoing. CONCLUSION Available data support an important role of androgens in female sexual function and dysfunction and efficacy of transdermal T therapy for the treatment of some women with FSD. Approved T formulations for women are generally unavailable. In consequence, the prescribing of T mostly involves off-label use of T products formulated for men and individually compounded T formulations. Long-term studies to determine the safety of T therapy for women and possible benefits beyond that of sexual function are greatly needed.

Abstract
Testosterone is an essential hormone for women, with physiological actions mediated directly or via aromatisation to oestradiol throughout the body. Despite the crucial role of testosterone and the high circulating concentrations of this hormone relative to oestradiol in women, studies of its action and the effects of testosterone deficiency and replacement in women are scarce. The primary indication for the prescription of testosterone for women is loss of sexual desire, which causes affected women substantial concern. That no formulation has been approved for this purpose has not impeded the widespread use of testosterone by women--either off-label or as compounded therapy. Observational studies indicate that testosterone has favourable cardiovascular effects measured by surrogate outcomes; however, associations between endogenous testosterone and the risk of cardiovascular disease and total mortality, particularly in older women, are yet to be established. Adverse cardiovascular effects have not been seen in studies of transdermal testosterone therapy in women. Clinical trials suggest that exogenous testosterone enhances cognitive performance and improves musculoskeletal health in postmenopausal women. Unmet needs include the availability of approved testosterone formulations for women and studies to elucidate the contribution of testosterone to cardiovascular, cognitive, and musculoskeletal health and the risk of cancer.

Abstract
Gender dysphoria (GD) is characterized by discomfort with the assigned or birth gender and the urge to live as a member of the desired sex. The goal of medical and surgical treatment is to improve the well-being and quality of life of transpeople. The acquisition of phenotypic features of the desired gender requires the use of cross-sex hormonal therapy (CHT). Adult transmen are treated with testosterone to induce virilization. In adolescents with severe and persistent GD, consideration can be given to arresting puberty at Tanner Stage II and if dysphoria persists, CHT is generally started after 16 years of age. Currently available short- and long-term safety studies suggest that CHT is reasonably safe in transmen. Monitoring of transmen should be more frequent during the first year of cross-sex hormone administration reducing to once or twice per year thereafter. Long-term monitoring after sex reassignment surgery (SRS) includes annual check-ups as are carried out for natal hypogonadal men. In elderly transmen, special attention should be paid to haematocrit in particular. Screening for breast and cervical cancer should be continued in transmen not undergoing SRS.

Abstract
INTRODUCTION Vasomotor symptoms (VMS) and the genitourinary syndrome of menopause (GSM) are recognized as the most frequent and bothersome symptoms associated with menopause. There are different treatments for both groups of symptoms, being necessary to individualize them. AREAS COVERED There are different therapies for VMS including hormonal treatments with estrogen, with and without progestins; the new alternative, tissue-selective estrogen complex (TSEC), tibolone, phytoestrogens and only progestins. Evidence also shows efficacy with selective serotonin reuptake inhibitors. Other nonhormonal alternatives exist as second-line treatments, all with not conclusive results. The GSM can be treated with nonhormonal treatments such as vaginal lubricants and moisturizers, other alternatives as vaginal laser needs to have more evidence. On the other hand, there is the possibility to use the hormonal treatments with systemic or local estrogen, which are the most effective treatment, the TSEC and the newest selective estrogen receptor modulator (SERM), ospemifene. Therapies with testosterone and dehydroepiandrosterone (DHEA) are still under study. The GSM can be treated with nonhormonal treatments such as vaginal lubricants and moisturizers, and other alternatives as vaginal laser need to have more evidence. On the other hand, there is the possibility to use the hormonal treatments with systemic or local estrogen, which are the most effective treatment, the TSEC and the newest SERM, ospemifene. Therapies with testosterone and DHEA are still under study. EXPERT OPINION The increasing numbers of therapies for menopausal symptoms open up new options, but we must individualize treatments. New possibilities arise in patients who did not have them and which can improve compliance and is also important to design strategies using combined or sequential treatments.

Abstract
INTRODUCTION Metabolic disorders, such as type 2 diabetes, have been associated with an increased risk of development of female sexual dysfunction (FSD). In experimental studies, vascular, neuronal, and hormonal responsiveness alteration at vaginal level were proposed as contributors to the onset of FSD in women with diabetes; however, conclusive data on humans are still lacking. AIMS The study aimed to assess changes in vascularization, sex steroid receptors, nitric oxide synthase, and aquaporin-2 (AQP2) expression occurring at vaginal level in women with diabetes. METHODS Vaginal biopsies were obtained from 21 postmenopausal women, 10 of whom were diagnosed as having type 2 diabetes mellitus. CD31, estrogen receptor-α (ERα) and androgen receptor (AR) expression and localization were analyzed by immunostaining. Expression of endothelial (eNOS) and neuronal (nNOS) nitric oxide synthase isoforms and AQP2 were also assessed in vaginal samples. MAIN OUTCOMES MEASURES Changes in vaginal vascularization, sex steroids receptor, eNOS, nNOS and AQP2 expression. RESULTS Vaginal samples from women with diabetes showed an increased microvessel density in the lamina propria, which were morphologically disrupted suggesting an angiogenic compensatory mechanism. While no differences were seen in ERα, AR expression was significantly reduced in the vaginal epithelium and lamina propria of women with diabetes. Similarly, the gene and protein expressions of both nNOS and eNOS were significantly reduced in patients with diabetes, while AQP2 mRNAs level did not significantly differ between the two groups. CONCLUSION Diabetes greatly impacts vaginal physiology, being associated with alterations of the vaginal lamina propria vascular network, nitrergic signaling, and AR expression. These alterations may contribute to the increased risk of FSD development in women with diabetes.

Abstract
OBJECTIVE Women with breast cancer who are treated with aromatase inhibitors often experience vaginal atrophy symptoms and sexual dysfunction. This work aims to study proliferation and the presence and distribution of steroid hormone receptors in vaginal biopsies in relation to vaginal atrophy and vaginal pH in women with breast cancer who are on adjuvant endocrine treatment and in healthy postmenopausal women. METHODS This is a cross-sectional study that compares postmenopausal aromatase inhibitor-treated women with breast cancer (n = 15) with tamoxifen-treated women with breast cancer (n = 16) and age-matched postmenopausal women without treatment (n = 19) or with vaginal estrogen therapy (n = 16). Immunohistochemistry was used to study proliferation and steroid hormone receptor staining intensity. Data was correlated with estrogen and androgen levels, vaginal atrophy scores, and vaginal pH. RESULTS Aromatase inhibitor-treated women had a lower grade of proliferation, weaker progesterone receptor staining, and stronger androgen receptor staining, which correlated with plasma estrone levels, vaginal atrophy scores, and vaginal pH. CONCLUSIONS Women with aromatase inhibitor-treated breast cancer exhibit reduced proliferation and altered steroid hormone receptor staining intensity in the vagina, which are related to clinical signs of vaginal atrophy. Although these effects are most probably attributable to estrogen suppression, a possible local inhibition of aromatase cannot be ruled out.

Abstract
To date, the effects of long-term testosterone (T) administration on the human vagina are not completely understood. Thus, the aim of this study was to investigate the effects of long-term T treatment on vaginal tissue histology, estrogen receptor alpha (ERα) and beta (ERβ) expression and proliferation in female to male transsexual subjects (FtM). We compared vaginal samples from FtM subjects with those of premenopausal women (PrM) and postmenopausal women (M) not receiving any hormonal treatment for at least 2 years. Vaginal tissue samples from 16 FtM subjects treated with T (intramuscular injections of 100 mg Testoviron Depot/7-10 days for at least 1 year), undergoing sex reassignment surgery, and 16 PrM and 16 M subjects undergoing a vaginal hysterectomy for prolapse, were collected. For each sample, morphology, glycogen content, proliferation (ki-67), ERα and ERβ expression were evaluated. Vaginal samples from FtM showed a loss of normal architecture of the epithelium, intermediate and superficial layers were completely lost, and glycogen content was depleted. T administration resulted in a strong proliferation reduction when compared with both M and PrM subjects. Stromal and epithelial ERα as well as ERβ were significantly decreased in FtM when compared with PrM subjects. In conclusion, our data suggests that systemic T administration at supraphysiological dosage, determines profound changes in histomorphology and reduces ERs expression and proliferation of vaginal epithelium.
