Postmenopausal Hyperandrogenism: Evaluation and Treatment Strategies

Hyperandrogenism after menopause: diagnostic evaluation

Excessive androgen levels in women after menopause often result from an imbalance in ovarian steroid secretion: a rapid decline in estrogen secretion associated with a slow decrease in androgen secretion, compounded by a physiological decrease in sex hormone-binding globulin. Hyperandrogenism is associated with a higher risk of cardiovascular events and gynecological neoplasms, also impacting the emotional well-being of affected women. Therefore, the aim of these guidelines is to guide the clinical physician in the appropriate clinical and biochemical evaluation of hyperandrogenism after menopause, thus optimizing therapeutic outcomes. The most frequent consultation in this stage of life is facial hirsutism associated with hair loss. If the onset of signs is abrupt, severe, associated with virilization and accompanied by serum testosterone levels in the male range, it is necessary to rule out a tumoral origin. A thorough medical history guides the diagnosis. Determination of total testosterone using reliable methods and imaging studies are valid tools to assist when doubts arise in the differential diagnosis.

Endogenous androgens, coronary atheroma and remodeling in women with suspected ischemic heart disease: A report from the Women's Ischemia Syndrome Evaluation (WISE) study

Background

Women have smaller coronary size than men independent of body surface area. Female to male heart transplantation demonstrates coronary lumen enlargement.

Purpose

To investigate relationships between endogenous androgens and coronary luminal size in women with suspected ischemic heart disease (IHD).

Methods

We analyzed 69 women with available androgen levels.

Results

Group mean age was 54 ± 10 years with 64 % post-menopausal. Lumen cross-sectional area (CSA) and external elastic membrane (EEM) CSA positively correlated with free testosterone (FT) (r = 0.29, p = 0.049; r = 0.29, p = 0.01), respectively, and negatively correlated with SHBG (r = -0.26, p = 0.03; r = -0.29, p = 0.02), respectively. Atheroma CSA positively correlated with FT (r = 0.24. p = 0.05). These correlations became non-significant after adjusting for waist circumference.

Conclusions

In women with suspected ischemic heart disease, endogenous androgens, coronary atheroma and luminal size are related, and may be moderated by waist circumference.

Leydig tumor in normal sized ovaries causing clitoromegaly: A case report

We describe an unusual presentation of a rare Leydig tumor presenting in bilateral ovaries that are otherwise normal in size for postmenopausal women. A 66-year-old woman presented with postmenopausal bleeding and during her work-up acutely developed clitoromegaly. Her diagnostic work-up revealed a 1.8 cm left ovarian complex cyst and extremely elevated testosterone levels. Management included hysterectomy and bilateral salpingo-oophorectomy. Final pathology revealed Leydig tumors in the bilateral ovaries. This case discusses a rare presentation of a rare tumor and highlights the importance of a thorough examination of the female genitalia and investigation for root cause.

Aging and Adiposity-Focus on Biological Females at Midlife and Beyond

Menopause is a physiological phase of life of aging women, and more than 1 billion women worldwide will be in menopause by 2025. The processes of global senescence parallel stages of reproductive aging and occur alongside aging-related changes in the body. Alterations in the endocrine pathways accompany and often predate the physiologic changes of aging, and interactions of these processes are increasingly being recognized as contributory to the progression of senescence. Our goal for this review is to examine, in aging women, the complex interplay between the endocrinology of menopause transition and post-menopause, and the metabolic transition, the hallmark being an increasing tendency towards central adiposity that begins in tandem with reproductive aging and is often exacerbated post menopause. For the purpose of this review, our choice of the terms 'female' and 'woman' refer to genetic females.

Postmenopausal Hyperandrogenism Associated With Synchronous Ovarian Brenner Tumor, Bilateral Leydig Cell Tumor, and Adrenal Mass

Hyperandrogenism in postmenopausal females may arise from either ovarian or adrenal sources and can pose a challenging diagnostic dilemma. We present the case of a 66-year-old female with postmenopausal hyperandrogenism with virilization, adrenal incidentaloma, and concurrent finding of two extremely rare ovarian tumors, including bilateral Leydig cell tumor and Brenner tumor. Laboratory tests showed elevated testosterone and androstenedione and normal dehydroepiandrosterone sulfate (DHEAS). Response to 1 mg overnight dexamethasone suppression test demonstrated persistently elevated testosterone and incomplete suppression of androstenedione. Computed tomography (CT) scan showed a left adrenal nodule and an unremarkable appearance of the ovaries. The pelvic ultrasound did not show an ovarian tumor on the right ovary, and the left ovary was not seen. Adrenal and ovarian vein sampling suggested the ovaries as the source of the testosterone. Given the ovarian vein sampling results, a multidisciplinary discussion between endocrinology and gynecologic oncology concluded that bilateral salpingo-oophorectomy (BSO) was the next best step for diagnosis and management. Laparoscopic BSO was performed. Histopathology showed bilateral Leydig cell tumors and a left ovarian Brenner tumor. At one-year postoperative follow-up, alopecia improved, and testosterone level normalized. This case highlights the importance of diagnostic pathways and interdisciplinary collaboration in managing rare clinical scenarios of hyperandrogenism in postmenopausal females. As in our case, surgeons may be hesitant to remove normal-appearing ovaries. While the three presented tumor types in this case arise from distinct tissues and exhibit different histological characteristics, the presence of such a unique triad prompts consideration of potential unifying pathogenic mechanisms.

The value of ovarian hyperstimulation syndrome in predicting pregnancy outcome in women with polycystic ovarian syndrome and candidate for in vitro fertilization: A case-control study

Background: Ovarian hyperstimulation syndrome (OHSS) as a known complication in women with polycystic ovarian syndrome (PCOS) may occur following inducible fertility treatments such as in vitro fertilization (IVF) and can affect the sequels of these treatments. Objective: This study aimed to assess the effects of OHSS on pregnancy outcomes through IVF in women with PCOS. Also, we assessed the value of baseline sexual hormones to predict the pregnancy's success. Materials and Methods: This case-control study was conducted on 180 consecutive women suffering from PCOS who were candidates for IVF at Fatemieh hospital in Hamadan, Iran, from May-July 2022. The women were assigned to the case group (with OHSS, n = 129) and the control group (without OHSS, n = 51). Measuring the sexual hormones was performed using the enzyme-linked immunosorbent technique. Results: In the multivariable logistic regression model, OHSS could not predict the likelihood of clinical or chemical pregnancy following IVF. None of the baseline sexual hormones could predict the successful chemical or clinical pregnancy in PCOS women following IVF. Conclusion: OHSS may not influence IVF-related outcomes in PCOS women. The values of sexual hormones may not also determine the pointed outcome.

Clinical Utility of GnRH Analogues in Female Androgen Excess: Highlighting Diagnostic and Therapeutic Applications

Female androgen excess typically presents with hirsutism, acne, and frontotemporal alopecia. Although the majority of cases are due to underlying polycystic ovary syndrome, non-polycystic ovary syndrome pathology can present a diagnostic and therapeutic challenge. We present 3 cases highlighting the utility of GnRH analogues in diagnosis and treatment of ovarian hyperandrogenism. In case 1, we highlight the role of GnRH analogue testing to localize severe postmenopausal androgen excess, allowing full resolution of symptoms following resection of a benign ovarian steroid-cell tumor. Our second case demonstrates the dual utility of GnRH analogues as both a diagnostic and therapeutic agent for hyperandrogenism in a premenopausal woman with severe insulin resistance. We observed suppression of serum testosterone coupled with significant improvement in hirsutism scores. The final case describes GnRH analogue suppression as a therapeutic option for a postmenopausal woman with ovarian hyperthecosis wishing to avoid surgical intervention, with successful symptom resolution. This case series delineates the applications of GnRH analogue suppression in a variety of clinical contexts, in particular their potential role in controlling symptoms in cases of refractory androgen excess and an alternative to surgery in cases of benign ovarian hyperandrogenism.

Ovarian Leydig Cell Tumor and Ovarian Hyperthecosis in a Postmenopausal Woman: A Case Report and Literature Review

Ovarian Leydig cell tumor is a rare type of ovarian steroid cell neoplasms, presenting in only 0.1% of all ovarian tumor cases, and is generally androgen-secreting and unilateral. Although they are often malignant non-spreading tumors, which have excellent prognosis, benign ovarian Leydig cell tumors with low-risk malignancy can be also detected. Ovarian hyperthecosis is a rare non-neoplastic disorder, in most cases bilateral. Ovarian tumors and ovarian hyperthecosis are one of the main causes of hyperandrogenism in postmenopausal women, a condition strongly associated with both hormonal and metabolic changes. Here, we report a 65-year-old patient with complaints of excessive body hairiness and alopecia. The laboratory investigation showed increased levels of serum testosterone and dehydroepiandrosterone sulfate (DHEA-S). Imaging, including transvaginal ultrasound and pelvic MRI revealed the presence of two masses in the ovaries. The patient underwent a laparoscopic bilateral salpingo-oophorectomy due to the ovarian tumors unknown etiology, and histopathological examination revealed a unilateral benign left ovarian Leydig cell tumor with bilateral ovarian stromal hyperplasia and ovarian hyperthecosis. Making differential diagnosis between ovarian tumors and ovarian hyperthecosis is difficult. Bilateral salpingo-oophorectomy is the treatment of choice in postmenopausal women with benign Leydig cell ovarian tumor, as well as ovarian hyperthecosis, as it offers both a cure and diagnostic confirmation.

Surgical treatment of post-menopausal ovarian hyperandrogenism improves glucometabolic profile alongside clinical hirsutism

Hyperandrogenism during menopause is often underestimated by clinicians and attributed to the natural aging process. Hyperandrogenism can be associated with some metabolic abnormalities linked together in a vicious circle by insulin resistance. We present the case of an elderly woman affected with type 2 diabetes and obesity who reported the occurrence of clinical hirsutism after physiological menopause at the age of 47 years. At presentation, physical examination and Ferriman-Gallwey score revealed a condition of moderate hirsutism, with markedly increased levels of plasma testosterone and delta-4-androstenedione, obesity (body mass index 31.9), and inadequate glycemic control (glycated hemoglobin 65 mmol/mol). The patient underwent a thorough differential diagnosis by a multidisciplinary team approach, including the various causes of hyperandrogenism during menopause. After choosing surgical option as the appropriate treatment, clinical resolution of hirsutism was observed alongside patient satisfaction and marked improvement of the glucometabolic profile.

Hyperandrogenic Symptoms Are a Persistent Suffering in Midlife Women with PCOS; a Prospective Cohort Study in Sweden

Polycystic ovary syndrome (PCOS) is a common endocrine disorder among women, and the majority suffers from hyperandrogenism. Hyperandrogenism causes psychological morbidity and impaired quality of life in women with PCOS during the reproductive years, but data on prevalence and impact during midlife are lacking. Thus, this study aimed to address whether hyperandrogenism persists into midlife and, if so, what impact it has on quality of life. In order to answer this question, we performed a multicenter prospective cohort study, where we included women already diagnosed with PCOS who had reached the age of 45 years or more and age-matched controls. All participants underwent a physical exam, structured medical interview, biochemical testing and filled out self-assessment questionnaires. More than 40% of the women with PCOS and 82% of those who presented with the hyperandrogenic phenotype at the diagnostic work-up still suffered from hirsutism. Circulating testosterone levels were similar between women with PCOS and controls while free androgen index was higher in women with PCOS, independent of weight. Women with hyperandrogenic PCOS expressed persisting concerns regarding hirsutism at the follow-up assessment. In conclusion, women with PCOS who present with hyperandrogenic symptoms at the time they are diagnosed with PCOS have a higher risk of persistent androgenic symptoms and impaired quality of life in midlife.

Approach to Investigation of Hyperandrogenism in a Postmenopausal Woman

Postmenopausal hyperandrogenism is a condition caused by relative or absolute androgen excess originating from the ovaries and/or the adrenal glands. Hirsutism, i.e., increased terminal hair growth in androgen-dependent areas of the body, is considered the most effective measure of hyperandrogenism in women. Other symptoms can be acne and androgenic alopecia or the development of virilization including clitoromegaly. Postmenopausal hyperandrogenism may also be associated with metabolic disorders like abdominal obesity, insulin resistance and type 2 diabetes. Mild hyperandrogenic symptoms can be due to relative androgen excess associated with menopausal transition or polycystic ovary syndrome, which is likely the most common cause of postmenopausal hyperandrogenism. Virilizing symptoms, on the other hand, can be caused by ovarian hyperthecosis or an androgen-producing ovarian or adrenal tumor that may be potentially malignant. Determination of serum testosterone, preferably by tandem mass spectrometry, is the first step in the endocrine evaluation providing important information on the degree of androgen excess. Testosterone > 5 nmol/L is associated with virilization and requires prompt investigation to rule out an androgen-producing tumor in first instance. To localize the source of androgen excess, imaging techniques are used like transvaginal ultrasound or magnetic resonance imaging (MRI) for the ovaries and computed tomography (CT) and MRI for the adrenals. Bilateral oophorectomy or surgical removal of an adrenal tumor is the main curative treatment and will ultimately lead to a histopathological diagnosis. Mild to moderate symptoms of androgen excess are treated with anti-androgen therapy or specific endocrine therapy depending on diagnosis. This review summarizes the most relevant causes of hyperandrogenism in postmenopausal women and suggests principles for clinical investigation and treatment.

The Roles of Androgens in Humans: Biology, Metabolic Regulation and Health

Androgens are an important and diverse group of steroid hormone molecular species. They play varied functional roles, such as the control of metabolic energy fate and partition, the maintenance of skeletal and body protein and integrity and the development of brain capabilities and behavioral setup (including those factors defining maleness). In addition, androgens are the precursors of estrogens, with which they share an extensive control of the reproductive mechanisms (in both sexes). In this review, the types of androgens, their functions and signaling are tabulated and described, including some less-known functions. The close interrelationship between corticosteroids and androgens is also analyzed, centered in the adrenal cortex, together with the main feedback control systems of the hypothalamic-hypophysis-gonads axis, and its modulation by the metabolic environment, sex, age and health. Testosterone (T) is singled out because of its high synthesis rate and turnover, but also because age-related hypogonadism is a key signal for the biologically planned early obsolescence of men, and the delayed onset of a faster rate of functional losses in women after menopause. The close collaboration of T with estradiol (E2) active in the maintenance of body metabolic systems is also presented Their parallel insufficiency has been directly related to the ravages of senescence and the metabolic syndrome constellation of disorders. The clinical use of T to correct hypoandrogenism helps maintain the functionality of core metabolism, limiting excess fat deposition, sarcopenia and cognoscitive frailty (part of these effects are due to the E2 generated from T). The effectiveness of using lipophilic T esters for T replacement treatments is analyzed in depth, and the main problems derived from their application are discussed.

Association between testosterone levels and bone mineral density in females aged 40-60 years from NHANES 2011-2016

Growing evidence indicates that testosterone is a conspicuous marker for assessing male bone mineral density (BMD). However, research regarding testosterone levels and BMD is sparse and controversial for females. Hence, we aimed to investigate the association between testosterone levels and BMD among adult females aged 40–60 years in the United States. In this cross-sectional study, all participants were part of the National Health and Nutrition Examination Survey (2011–2016). A weighted general linear model was used to estimate the association between testosterone levels and lumbar BMD. Age, race, income level, education level, body mass index (BMI), blood urea nitrogen (BUN) level, serum uric acid (UA) level, serum calcium (Ca) level, serum phosphorus (P) level, the use of oral contraceptive pills, the use of hormone replacement therapy (HRT), smoking status, drinking status, and the use of corticosteroids were adjusted using a weighted multiple regression model. Subgroup analyses were performed using the same regression model. We included 2198 female participants in the study, and testosterone levels were positively associated with lumbar BMD after adjusting for all the covariates (β = 1.12, 95% CI 0.31, 1.93). In subgroup analyses, the associations in the fourth quartile of testosterone levels were stronger for the participants aged 40–50 years old (quartile 4, β = 42.92, 95% CI 7.53, 78.30 vs. quartile 1) and 50 to 60-year-old (quartile 4, β = 32.41, 95% CI 0.14, 64.69 vs. quartile 1). Similar results were found in other subgroups, including subgroups for race (Non-Hispanic Black, Other), income level (income ≤ 1.3, income > 3.5), education level (college or higher), BMI > 25 kg/m², BUN levels ≤ 20 mg/dL, UA levels ≤ 6 mg/dL, Ca levels ≤ 10.1 mg/dL, P levels ≤ 5 mg/dL, drinking status, never smoker, never taking birth control pills, and HRT user. There was no interaction among the covariates in the association between lumbar BMD and testosterone levels (P for interaction > 0.05). In US adult females aged 40–60 years, the testosterone level was a positive predictor of the lumbar BMD after adjusting for covariates.
