[PMID: 38590820 PMCID: PMC10999583 DOI: 10.3389/fendo.2024.1294638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 03/12/2024] [Indexed: 04/10/2024] Open
Abstract
As the incidence of type 2 diabetes mellitus (T2DM) is increasing rapidly and its consequences are severe, effective intervention and prevention, including sleep-related interventions, are urgently needed. As a component of sleep architecture, naps, alone or in combination with nocturnal sleep, may influence the onset and progression of T2DM. Overall, napping is associated with an increased risk of T2DM in women, especially in postmenopausal White women. Our study showed that napping >30 minutes (min) increased the risk of T2DM by 8-21%. In addition, non-optimal nighttime sleep increases T2DM risk, and this effect combines with the effect of napping. For nondiabetic patients, napping >30 min could increase the risks of high HbA1c levels and impaired fasting glucose (IFG), which would increase the risk of developing T2DM later on. For diabetic patients, prolonged napping may further impair glycemic control and increase the risk of developing diabetic complications (e.g., diabetic nephropathy) in the distant future. The following three mechanisms are suggested as interpretations for the association between napping and T2DM. First, napping >30 min increases the levels of important inflammatory factors, including interleukin 6 and C-reactive protein, elevating the risks of inflammation, associated adiposity and T2DM. Second, the interaction between postmenopausal hormonal changes and napping further increases insulin resistance. Third, prolonged napping may also affect melatonin secretion by interfering with nighttime sleep, leading to circadian rhythm disruption and further increasing the risk of T2DM. This review summarizes the existing evidence on the effect of napping on T2DM and provides detailed information for future T2DM intervention and prevention strategies that address napping.

Dig Liver Dis 2023; 55:1091-1097. [PMID: 36922303 DOI: 10.1016/j.dld.2023.02.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 02/13/2023] [Accepted: 02/26/2023] [Indexed: 03/18/2023]
Abstract
BACKGROUND Primary biliary cholangitis (PBC) primarily affects female in their 4th to 6th decade of life at which stage female's sex hormones change dramatically. Sex hormones have a wide range of effects on the liver and immune system. However, it remains unclear whether sex hormonal changes mediate the onset of PBC. AIMS This study investigated the causal effect between total testosterone (TT), bioavailable testosterone (BAT), sex hormone binding globulin (SHBG) in female and PBC using public GWAS summary data. METHODS Data on TT, BAT, SHBG in female were obtained from a previous study based on the UK Biobank. PBC GWAS summary data was obtained from a genome-wide meta-analysis. We used several methods to make the conclusion robust. Various sensitivity analyses had been conducted to assess the consistency of our findings. RESULTS Our Mendelian randomization analysis revealed that the genetically predicted BAT in female was positively associated with PBC and SHBG in female was negatively associated with PBC. The results obtained from different methods are similar, which proves the reliability of the results. CONCLUSIONS Our study supported a causal relationship of BAT and SHBG in female on PBC. To confirm the association between testosterone and PBC, more research should be conducted.

Kar D, Roy S. Factors associated with the CVD risk factors and body fat pattern of postmenopausal Hindu caste and Lodha tribal populations living in India: An exploratory study. Womens Midlife Health 2023; 9:4.

Abstract
BACKGROUND Loss in ovarian function during mid-life results in adverse changes in the cardiovascular profile of women. The association between CVD risk factors and menopause differ cross-culturally since several modifiable factors play significant roles in explaining CVD mortality in addition to differences in endogenous estrogen. Very few of the studies from the Indian subcontinent have been concerned with the menopause-specific CVD risk factors, particularly among the tribal groups. Thus, we intended to study the variations in body fat pattern and CVD risk factors between Hindu caste and Lodha tribal postmenopausal women and how these risk factors were associated with differential socio-economic, reproductive and menstrual characteristics and lifestyle variables. The Lodha tribal populations is considered a Particularly Vulnerable Group (PVTG) in this country. METHODS This cross-sectional study was conducted among the Bengali Hindu caste and Lodha tribal populations of the State of West Bengal, India covering three districts namely Howrah, Jhargram and East Midnapure. A total of 197 postmenopausal participants were recruited for this study (urban caste 69, rural caste 65 and rural Lodha 63). Data on blood glucose and total cholesterol levels, blood pressure, muscle mass, body fat distribution and sociodemographic, reproductive and menstrual history and lifestyle variables were collected following standard protocols. Analysis of variance (ANOVA) was applied to compare blood glucose, total cholesterol and blood pressure levels and body fat measures across the three populations. Stepwise multiple linear regression analysis was performed to find out the factors associated with CVD risk factors. The data were analyzed with the Statistical Package for Social Science version 20.0(IBM corporation, 2011). RESULTS This cross-sectional comparison of women at midlife, though exploratory in nature showed significant differences in body fat pattern and CVD risk factors between caste and tribal groups owing to socioeconomic disparities and, differences in reproductive characteristics and lifestyle factors. CONCLUSION The caste and tribal populations differed significantly in body fat pattern and CVD risk factors and in the factors associated with CVD risk suggesting interplay between menopause and modifiable factors in explaining CVD risk factors during mid-life.

Examining the Role of Physical Activity Interventions in Modulating Androgens and Cardiovascular Health in Postmenopausal Women: A Narrative Review. CJC Open 2022; 5:54-71. [PMID: 36700183 PMCID: PMC9869362 DOI: 10.1016/j.cjco.2022.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 10/11/2022] [Indexed: 11/10/2022] Open
Abstract
A growing body of literature has examined the role of physical activity (PA) in modifying the effects of estrogen withdrawal on cardiovascular health in postmenopausal women, but the impact of PA on androgens is less clear. Changes in androgen concentrations following regular PA may improve cardiovascular health. This narrative review summarizes the literature assessing the impact of PA interventions on androgens in postmenopausal women. The association between changes in androgen concentrations and cardiovascular health following PA programs is also examined. Randomized controlled trials were included if they (i) implemented a PA program of any type and duration in postmenopausal women and (ii) measured changes in androgen concentrations. Following PA interventions, no changes in androstenedione, conflicting changes in dehydroepiandrosterone/dehydroepiandrosterone-sulfate, and increases in sex hormone-binding globulin concentrations were found. Total testosterone decreased following aerobic PA but increased after resistance training. Most aerobic PA interventions led to reductions in free testosterone. A combination of caloric restriction and/or fat loss enhanced the influence of PA on most androgens. Evidence exploring the relationship between changes in androgens and cardiovascular health indicators was scarce and inconsistent. PA has shown promise in modifying the concentrations of some androgens (free and total testosterone, sex hormone-binding globulin), and remains a well-known beneficial adjuvant option for postmenopausal women to manage their cardiovascular health. Fat loss influences the effect of PA on androgens, but the synergistic role of PA and androgens on cardiovascular health merits further examination. Many research gaps remain regarding the relationship between PA, androgens, and cardiovascular disease in postmenopausal women.

Abstract
To investigate whether there is an association between androgens and ovarian reserve, expressed through anti-Mullerian hormone. This is a retrospective cross-sectional analysis of all consecutive women attending a tertiary fertility center, who presented with regular menstrual cycles. Patients had their AMH values measured with the same AMH assay (Immunotech (IOT) Beckmann Coulter assay), the same day in which androgens sampling was performed. Women with PCOS or other forms of androgen excess or untreated endocrine or metabolic disorders were excluded. A total of 942 women were included. Significant correlation was observed between total testosterone/free androgens index (FAI)/DHEAS and AMH (Spearman's r = 0.20/0.14/0.13, P value < 0.001, P value < 0.001, and P value < 0.001, respectively). After multiple linear regression analysis adjusting for confounders (age, BMI, cause of infertility, day of the menstrual cycle when the blood sample was performed), the regression slope in all participants for total testosterone predicting logAMH was 0.20 (P value < 0.001). Similarly, FAI was significantly associated with logAMH (regression coefficient = 0.04, P value = 0.04). In contrast, DHEAS was not significantly associated with logAMH. There was a significant, but weak relation between testosterone and AMH, while no significant association was observed between DHEAS and AMH. Future research is needed to elucidate whether testosterone supplementation may have any effect on ovarian function.

Abstract
Objectives To determine the prevalence of obesity and its relationship with subclinical hypothyroidism in women with polycystic ovarian syndrome (PCOS). To compare the clinico-biochemical parameters of obese and lean PCOS patients. Materials and Methods A total of 287 women with PCOS were included in this study after consent. The demographic, anthropometry, clinical, and hormonal (thyroid-stimulating hormone [TSH] and total testosterone) parameters were recorded along with pelvic ultrasonography (USG) for all PCOS subjects. They were divided into lean (body mass index [BMI] between 18.5 and 22.9) and overweight (BMI ≥23), and the number of subclinical hypothyroid patients were calculated in each group. The clinico-biochemical parameters of both groups were compared. Results The majority (61%) of our patients were overweight. There was no significant difference in the prevalence of subclinical hypothyroidism between overweight and lean PCOS patients. The obese PCOS patients were older than lean PCOS patients, and they had higher serum testosterone with elevated systolic and diastolic blood pressure (BP). Conclusion The majority of our patients were found to be overweight and there was no association between obesity and subclinical hypothyroidism among PCOS patients.

Abstract
Cardiovascular disease is the leading cause of the death for both men and women. Although baseline heart physiology and the response to disease are known to differ by sex, little is known about sex differences in baseline molecular signaling, especially with regard to redox biology. In this review, we describe current research on sex differences in cardiac redox biology with a focus on the regulation of nitric oxide and aldehyde signaling. Furthermore, we argue for a new perspective on cardiovascular sex differences research, one that focuses on baseline redox biology without the elimination or disruption of sex hormones.

Abstract
CONTEXT Women with polycystic ovary syndrome (PCOS) have a higher prevalence of metabolic syndrome (MetS), but whether they develop MetS earlier than women without PCOS is unknown. Understanding the impact of PCOS on the timing of MetS onset is important for screening and clinical care in this population. DESIGN Women with PCOS-like status (PCOSp) were identified from participants of the Michigan Bone Health and Metabolism Study based upon history of irregular menstrual cycles, high free-androgen index, and high levels of antimüllerian hormone. MetS was defined according to the Adult Treatment Panel III criteria. Age at MetS onset was compared between women with and without PCOSp using an accelerated failure time model adjusted for baseline education, lifestyle factors, and midlife body weight. RESULTS Among the 496 women in the analysis, 11.7% (n = 58) were determined to have PCOSp. Over a mean follow-up of 11 years, 20 women with PCOSp and 136 women without PCOSp developed MetS. After adjusting for smoking, education, and physical activity, women with PCOSp developed MetS at an age 14.4% (95% CI -22.7, -5.2) younger than women without PCOSp. The magnitude of the association was attenuated to 5.4% in models additionally adjusted for body mass index (95% CI -12.4, 2.1). Because a typical study participant without PCOSp developed MetS at 51.5 years old, 5.4% translates to almost 3 years earlier onset of MetS for a comparable woman with PCOSp. CONCLUSIONS Women with PCOSp develop MetS at a younger age. Earlier screening for MetS in women with PCOS may be warranted.

Abstract
OBJECTIVE To assess influence of obesity and hormone disturbances on sexuality in the menopause. METHODS The study included 73 menopausal women, who were divided into groups according to body mass index (BMI) ≥ 26.7 kg/m2. Anthropometric characteristics and blood pressure were measured. Blood was taken at 08:00 for hormones. All the participants filled in McCoy Female Sexual Questionnaire for the assessment of sexual life. STATISTICS Student's t-test, correlation, analysis of variance (ANOVA). RESULTS Follicle-stimulating hormone (FSH), luteinizing hormone (LH) and sex hormone-binding globulin (SHBG) were very significantly lower in obese compared to controls. E2 and systolic blood pressure were very significantly, while diastolic blood pressure significantly higher in obese compared to controls. Obese women had significantly decreased frequency of pain during sexual intercourse (3.48 ± 2.64 vs. 4.09 ± 2.81). Influence of age on frequency of sexual intercourse was very significant. Significant influence in interaction between BMI and age on frequency of sexual fantasies as well as significant influence of BMI on satisfaction with partner as lover is also found. CONCLUSION Obesity has influence on different aspects of sexuality in the postmenopausal women. Our results suggest the need of awareness toward obesity and its impact on sexuality in the menopause.

Abstract
Skin is a target organ of sex steroids which play important roles in skin health and disease. The aim of this study is to investigate the expression of estrogen receptor β (ERβ) and androgen receptor (AR) in human skin from different age groups for a better understanding of the hormonal regulation of skin aging. Using standard immunohistochemical techniques, biopsies of sun-unprotected and sun-protected skin were taken from 60 normal subjects. Sun-protected skin showed significantly higher immunoreactivity for ERβ and AR compared to sun-unprotected skin of all age groups. Significantly higher ERβ H score and percent of expression were associated with the 20-35 years age group compared to the groups that were 35-50 years and >50 years old (p < 0.02, p = 0.03, respectively) in sun-unprotected and sun-protected skin (p < 0.001, p = 0.01, respectively). AR H score showed a negative correlation with age (p = 0.04) with no significant difference in immunoreactivity in different age groups, either in sun-unprotected or sun-protected skin. There was also a significant correlation between ERβ H score and epidermal thickness in sun-unprotected (p = 0.04) and sun-protected skin (p = 0.04) in studied subjects regardless of age. The same relationships did not reach significance with AR expression. However, a significant positive correlation was detected between H scores and percent of expression of ERβ and AR in sun-unprotected (p = 0.01, p = 0.02, respectively) and sun-protected skin (p = 0.005, p = 0.02, respectively) regardless of age. In conclusion, both ERβ and AR decline gradually with intrinsic and extrinsic aging. This decline is more obvious with extrinsic aging. Further large-scaled studies are recommended to expand, validate and translate current findings to clinically significant, diagnostic and therapeutic applications. Molecular studies to investigate the probable ligand-independent action of both receptors are warranted. In addition, their gene expression patterns and associated signaling and metabolic pathways can also be tackled to provide a basis for further interventions in pathological processes that involve their dysregulation.

Abstract
During menopause, women's body composition, sex hormone profile, and metabolic profile may change dramatically. In this review, we summarize studies examining whether the menopausal transition and physiologic factors characterizing the transition are associated with increased risk of diabetes. We review the evidence for estrogen therapy and diabetes risk and studies examining the relationship between diabetes and menarche, which represents an extension of the reproductive life span at the opposite end of the age spectrum. Although studied less extensively, the presence of type 1 or type 2 diabetes may increase the risk of ovarian failure, and we review this literature. In conclusion, we note that the evidence linking menopausal sex hormone changes with increased diabetes risk is weak, although rapid changes as observed with oophorectomy may increase risk. Further studies should investigate the contradictory effects of estrogen therapy upon hepatic and glucose metabolism in mid-life women.

Abstract
BACKGROUND Age-related changes in testosterone levels in older persons and especially in women have not been fully explored. The objective of this study was to describe age-related trajectories of total testosterone (TT), ammonium sulfate precipitation-measured bioavailable testosterone (mBT), and sex hormone-binding glycoprotein (SHBG) in men and women from the Baltimore Longitudinal Study of Aging, with special focus on the oldest adults. METHODS Participants included 788 White men and women aged 30-96 years with excellent representation of old and oldest old, who reported not taking medications known to interfere with testosterone. Longitudinal data were included when available. TT, mBT, and SHBG were assayed. Age-related trajectories of mBT were compared with those obtained using calculated bioavailable testosterone (cBT). Generalized least square models were performed to describe age-related trajectories of TT, mBT, and SHBG in men and women. RESULTS mBT linearly declines over the life span and even at older ages in both sexes. In men, TT remains quite stable until the age of 70 years and then declines at older ages, whereas in women TT progressively declines in premenopausal years and slightly increases at older ages. Differences in age-related trajectories between total and bioavailable testosterone are only partially explained by age changes in SHBG, whose levels increases at accelerated rates in old persons. Noteworthy, although mBT and cBT highly correlated with one another, mBT is a much stronger correlate of chronological age than cBT. CONCLUSION In both men and women, mBT linearly declines over the life span and even at old ages. Its relationship with age-related phenotypes should be further investigated.

Abstract
BACKGROUND Despite the high prevalence of depressive symptoms in women, the precise role of sex hormones in mood changes during the menopausal transition is unclear. Previous studies have been inconsistent with regard to identifying the association of androgens, namely total testosterone, with depressive symptoms. OBJECTIVE The objectives of this study were to evaluate changes in serum total testosterone levels and depressive symptoms during the entire menopausal transition, and examine the impact of covariates on the association between concurrent serum total testosterone levels and depressive symptoms during this time period. METHODS A longitudinal cohort study (428 women at baseline with 3634 repeated measures) using data from the Penn Ovarian Aging Study, a population-based cohort of late reproductive-aged women, followed through the menopausal transition. Serum hormone parameters and depression scores using the Center for Epidemiological Studies of Depression scale (CES-D) were measured at each annual visit over a 14-year period. General linear (for testosterone) and a generalized negative-binomial model (for depressive symptoms) for repeated measures were used for analysis. RESULTS Serum total testosterone levels increased progressively over the study period and were significantly associated with older age and with current smoking (p<0.001, respectively). In the post menopause total testosterone levels were significantly higher in African Americans compared to Caucasians (p=0.012). The proportion of women with CES-D ≥16 significantly decreased with increasing age and in the post-menopausal period, and were higher in women with a history of depression and hot flashes (p<0.001). The association between concurrent testosterone levels and high depressive symptoms (CES-D ≥16) differed by race (p=0.008). In Caucasians, but not African Americans, higher serum testosterone levels were associated with increased depressive symptoms after controlling for several variables including age, obesity status, hot flashes and menopausal status (RR 1.09, 95% CI 1.00-1.17, p=0.042). CONCLUSION In our cohort, testosterone levels were low but progressively increased from premenopause through post menopause. In addition to age and history of depression, we identified race to have a significant interaction between the association of testosterone levels and depressive symptoms. This study further supports the associations between sex hormones and increased risk of having depressive symptoms, although the precise underlying mechanisms for this association remain unclear.

Abstract
Human response to different physiologic stimuli and cardiovascular (CV) adaptation to various pathologies seem to be gender specific. Sex-steroid hormones have been postulated as the major contributors towards these sex-related differences. This review will discuss current evidence on gender differences in CV function and remodelling, and will present the different role of the principal sex-steroid hormones on female heart. Starting from a review of sex hormones synthesis, receptors and CV signalling, we will summarize the current knowledge concerning the role of sex hormones on the regulation of our daily activities throughout the life, via the modulation of autonomic nervous system, excitation-contraction coupling pathway and ion channels activity. Many unresolved questions remain even if oestrogen effects on myocardial remodelling and function have been extensively studied. So this work will focus attention also on the controversial and complex relationship existing between androgens, progesterone and female heart.

Abstract
This study examined whether grandmothers' smoking behavior during pregnancy was associated with birth weights in their grandchildren, considering possible birth cohort effects in the grandmothers' generation. The birth weights of 935 singleton children were compared by grandmothers' and mothers' smoking status during pregnancy. In 2008, women (n = 397) from the Michigan Bone Health and Metabolism Study were interviewed about their own birth history, including whether their own mother smoked while pregnant with them, and the birth histories of their offspring. While also accounting for family clustering, linear mixed models were used to evaluate whether birth weight differences in the grandchildren were associated with grandmothers' and mothers' smoking behavior during pregnancy. Associations were compared among grandmothers born from 1904 to 1928 versus grandmothers born from 1929 to 1945 to determine potential birth cohort effects. Forty-six (5 %) grandchildren had grandmothers and mothers who smoked while pregnant, while 455 (49 %) had grandmothers and mothers who did not smoke during pregnancy. After adjustment, birth weight was an average of 346 (95 % confidence interval 64-628) grams higher in grandchildren whose grandmother and mother both smoked during pregnancy relative to grandchildren whose grandmother and mother both did not smoke during pregnancy, but only among grandmothers who were born from 1929 to 1945. For grandmothers born from 1904 to 1928, grandchildren birth weights did not differ by grandmother and mother smoking status. Birth weight may be associated with grandmother and mother smoking behaviors during pregnancy, but birth cohort effects should be considered.

Abstract
CONTEXT Although there is evidence of metabolic risks in young women with irregular menses and androgen excess, persistence of risks after menopause is unclear. OBJECTIVE The objective of the study was to determine the impact of menopause on the cardiometabolic profile in women with high androgens and a history of menstrual irregularity. METHODS Study of Women's Health Across the Nation is a longitudinal cohort study. Data from 1929 women without metabolic syndrome (MetS) at baseline were analyzed for incidence of MetS, self-reported stroke, and myocardial infarction. Cox hazard ratios (HRs) were estimated, adjusting for age, ethnicity, body mass, smoking, menopausal status, and study site. RESULTS Among MetS-free women at baseline, 497 new cases were identified during 20 249 woman-years of follow-up over 12 years. Women with hyperandrogenemia (HA) and oligomenorrhea (Oligo) developed incident cases of MetS at a comparable rate compared with their counterparts: eumenorrheic, normoandrogenic women [HR 1.4 (0.9-2.2)], oligomenorrheic, normoandrogenic women [HR 1.3 (0.8-2.2)], and eumenorrheic hyperandrogenic women [HR 1.2 (0.7-1.8)]. Smoking and obesity were the strongest predictors of incident MetS. There was no significant difference in incidence of self-reported stroke or MI by HA/Oligo status. CONCLUSIONS Longitudinal evidence suggests that a history of androgen excess and menstrual irregularity is not associated with worsening of metabolic health after menopause. Our findings challenge the notion that a history of concurrent HA and Oligo reflects ongoing cardiometabolic risk in postmenopausal women.

Abstract
Endogenous sex hormones predict impairments of glucose regulation. Cross-sectional studies suggest that lower levels of testosterone in men and higher levels in women increase risk of metabolic syndrome and diabetes, whereas lower levels of sex hormone binding globulin in both men and women increase risk of metabolic syndrome and diabetes. In a systematic review, we summarize existing longitudinal studies, which suggest similar patterns. However, these studies are often limited to a single sex steroid measure. Whether these associations are primarily a marker of adiposity, and whether these associations differ between younger eugonadal vs older hypogonadal adults is also uncertain. The impact of exogenous sex steroid therapy may not reflect relationships between sex hormones and impaired glucose regulation that occur without supplementation. Therefore, examination of endogenous sex steroid trajectories and obesity trajectories within individuals might aid our understanding of how sex steroids contribute to glucose regulation.

Abstract
Pulmonary arterial hypertension (PAH), a form of pulmonary hypertension, is a complex disease of multifactorial origin. While new developments regarding pathophysiological features and therapeutic options in PAH are being reported, one important fact has emerged over the years: there is a sex difference in the incidence of this disease such that while there is a higher incidence in females, disease outcomes are much worse in males. Accordingly, recent attention has been focused on understanding the features of sex differences in the pulmonary circulation and the contributory mechanisms, particularly sex hormones and their role in the pathological and pathophysiological features of PAH. However, to date, there is no clear consensus whether sex hormones (particularly female sex steroids) are beneficial or detrimental in PAH. In this review, we highlight some of the most recent evidence regarding the influence of sex hormones (estrogen, testosterone, progesterone, dehydroepiandrosterone) and estrogen metabolites on key pathophysiological features of PAH such as proliferation, vascular remodeling, vasodilation/constriction, and inflammation, thus setting the stage for research avenues to identify novel therapeutic target for PAH as well as potentially other forms of pulmonary hypertension.

Abstract
AIMS The prevalence of hepatic steatosis may differ between post-menopausal African-American women and non-Hispanic white women and by sex hormone binding globulin level. We examined prevalence of hepatic steatosis by race/ethnicity and associations with sex hormone binding globulin. METHODS Participants included post-menopausal women who underwent hepatic ultrasound (n = 345) at the Michigan site of the Study of Women's Health Across the Nation, a population-based study. We examined hepatic steatosis prevalence by race/ethnicity and used logistic regression models to calculate the odds of hepatic steatosis with race/ethnicity and sex hormone binding globulin, after adjustment for age, alcohol use, waist circumference, high density lipoprotein cholesterol, triglycerides, systolic blood pressure and use of medications reported to lower intrahepatic fat. RESULTS Fewer African-American women than non-Hispanic white women had hepatic steatosis (23 vs. 36%, P = 0.01). African-American women had lower triglyceride and low-density lipoprotein cholesterol levels, but higher blood pressure and follicle-stimulating hormone levels (P < 0.05). In the optimal-fitting multivariable models, women in the highest tertile of sex hormone binding globulin (60.2-220.3 nmol/l) had a lower odds of hepatic steatosis (odds ratio 0.43, 95% CI 0.20-0.93) compared with women in the lowest tertile of sex hormone binding globulin (10.5-40.3 nmol/l). There was an interaction between race/ethnicity and medication use whereby non-Hispanic white women using medications had three times higher odds of hepatic steatosis compared with African-American women not using medications (odds ratio 3.36, 95% CI 1.07-10.58). Interactions between race/ethnicity and other variables, including sex hormone levels, were not significant. CONCLUSIONS Hepatic steatosis on ultrasound may be more common in post-menopausal non-Hispanic white women than African-American women and was associated with lower levels of sex hormone binding globulin.

Abstract
BACKGROUND The importance of surface epithelium and epithelial inclusion cysts in the ovary arises from studies demonstrating that these structures are susceptible to epithelial ovarian cancer development. The expression of estrogen receptor alpha (ER alpha), androgen receptor (AR), in epithelial cells of the ovary from premenopausal and postmenopausal women is interesting because sexual steroid hormones are involved in cell growth and differentiation. METHODS The presence of ER alpha, AR, and the orphan G protein-coupled receptor 30 (GPR30) was demonstrated by immunofluorescence in ovaries obtained from 79 pre and postmenopausal patients, undergoing histero-salpingo-oophorectomy for proliferative gynecological diseases. The proportion of patients that displayed positive reaction for estrogen and androgen receptors in epithelial cells of the ovary was evaluated according to menopausal status and associated pathology. RESULTS The proportion of patients that displayed a positive receptor expression in the epithelial cells of the ovarian surface and cortical inclusion cysts shows that ER alpha is present in 20 of 79 patients (0.25), AR in 33 of 79 (0.42) and GPR30 in 38 of 55 (0.69). There are no differences in ER alpha, AR, and GPR30 expression between pre and postmenopausal patients and considering the associated pathology, proportions for ER alpha and GPR30 are similar. The patients with cervical cancer show a higher proportion of AR expression in epithelial cells of the ovary, which is statistically significant (P < 0.01) compared with patients with other proliferative diseases. CONCLUSIONS The presence of ER alpha, AR, and GPR30 in the surface epithelial ovarian cells and its derivatives are observed with a proportion that is specific for each receptor. The proportion of expression for these receptors in the epithelial cells of the ovary does not change after menopause. The proportion of ovaries with AR positive epithelial cells in patients with cervical squamous carcinoma is higher compared with other gynecological pathologies.

Abstract
OBJECTIVE Sex hormones are thought to play an important role in the pathophysiology of depressive disorders in women. This study assessed the associations of total testosterone (T), bioavailable T, estradiol, dehydroepiandrosterone, and sex hormone-binding globulin (SHBG) with depressive symptoms stratified on postmenopausal stage to determine whether the associations were strongest for early postmenopausal women. METHODS Women (N = 1,824) free of depressive symptoms at baseline (2000-2002) in the Multiethnic Study of Atherosclerosis were categorized into tertiles of years postmenopause: T1, 0 to 10 years; T2, 11 to 20 years; and T3, 21 to 58 years. Multivariable-adjusted relative risks (RRs) and 95% CIs were computed for the incidence of depressive symptoms, as defined by a score of 16 or higher on the Center for Epidemiologic Studies Depression scale at examination 3 (2004-2005). RESULTS In analysis including all sex hormones, the RR for incident depressive symptoms associated with 1 unit higher log total T was 0.57 (P = 0.13), with log estradiol was 0.78 (P = 0.04), with log SHBG was 1.84 (P = 0.003), and with log dehydroepiandrosterone was 1.45 (P = 0.08) in T1. Without adjustment for SHBG, the RR for log bioavailable T was 0.16 (P = 0.04). However, in T2 and T3, there were no meaningful associations of hormone or SHBG levels with incident depressive symptoms. When stratified by HT use, results were consistent for HT users but attenuated for HT nonusers. CONCLUSIONS In early postmenopausal women, sex hormones were associated with incident depressive symptoms.

Abstract
OBJECTIVE(S) To determine the normative cut-off value for the free androgen index (FAI) among reproductive-age women in China. DESIGN Cross-sectional, population-based study. SETTING A multistage systematic cluster random sampling among 16 communities from two rural and two city regions. PATIENT(S) A total of 1526 women were randomly selected from a representative sample of 3009 women aged 20-45 years from the general population of southern China. Among these women, 444 subjects without known factors affecting androgen levels were selected as the reference group. INTERVENTION(S) Subjects underwent physical examination, blood tests of hormone and metabolic profiles, and ultrasound evaluations. MEASUREMENT OF THE MAIN OUTCOMES: The FAI was calculated according to the following equation: FAI = 100 × total testosterone (nmol/l)/sex hormone-binding globulin (nmol/l). The normative cut-off value of the FAI was computed based on the 5th-95th percentiles and K-means cluster analysis (K = 2). RESULTS A reference range of 0·7-6·4 of the FAI was indicated by the 5th and 95th percentiles. K-means cluster analysis identified 6·1 as the cut-off value for the FAI in the total population, which was close to the upper limit determined by the 95th percentile. Hyperandrogenic women present with elevated risk factors for metabolic disorders. The mean FAI values decreased with age among the total population, as evaluated by either K-means clustering or a percentile analysis. The FAI value was negatively correlated with age (r = -0·185, P < 0·0001) and positively correlated with body mass index after adjustment for age (r = 0·250, P < 0·0001). CONCLUSION A reference range of 0·7-6·4 FAI was indicated by the 5th and 95th percentiles among the reference group, which excluded the subjects with factors known to affect androgen levels; 6·1 was identified by the K-means cluster analysis as the cut-off value of the FAI for the general population. Hyperandrogenic women present with higher risks for metabolic disorders.

Abstract
OBJECTIVE We examined (1) the change in circulating adiponectin in women during the menopausal transition and (2) the associations of adiponectin levels with estrogen, androgen and sex hormone-binding globulin (SHBG) in women during the menopausal transition. METHODS We conducted a cross-sectional study in 235 healthy women and divided them into 7 stages by menstrual regularity and follicle-stimulating hormone (FSH) level. Serum levels of adiponectin, estradiol, total testosterone, dehydroepiandrosterone-sulfate (DHEA-S) and SHBG were measured. Levels of free and bioavailable testosterone were calculated by using total testosterone, albumin and SHBG. RESULTS Serum adiponectin levels showed a U-curve, levels being low in early and late menopausal transition and gradually becoming higher after menopause. Adiponectin levels were negatively correlated with levels of free testosterone, bioavailable testosterone and DHEA-S and were positively correlated with SHBG in postmenopausal women for whom more than 1 year had passed since menopause. Adiponectin level was not correlated with estradiol level. CONCLUSION Circulating adiponectin level shows a U-curve during the menopausal transition and adiponectin level is associated with levels of free and bioavailable testosterone and DHEA-S in postmenopause.

Abstract
CONTEXT Young reproductive-age women with irregular menses and androgen excess are at high risk for unfavorable metabolic profile; however, recent data suggest that menstrual regularity and hyperandrogenism improve with aging in affected women approaching menopause. OBJECTIVE The objective of the study was to determine whether women with hyperandrogenemia (HA) and a history of oligomenorrhea (Oligo) are at an elevated risk for metabolic syndrome (MetS) at the early stages of menopausal transition. METHODS Baseline data from 2543 participants (mean age of 45.8 yr) in the Study of Women's Health Across the Nation were analyzed. Women with a lifetime history of more than one 3-month interval of nongestational and nonlactational amenorrhea were classified as having a history of Oligo. The highest tertile of serum testosterone was used to define HA. Women with normal serum androgens and eumenorrhea were used as the reference group. Logistic regression models generated adjusted odds ratios (AOR), controlling for age, ethnicity, body mass index, smoking, and study site. RESULTS Oligo was associated with MetS only when coincident with HA [AOR of 1.93 for Oligo and HA [95% confidence interval (CI) 1.17-3.17], AOR of 1.25 for Oligo and normal androgens (95% CI 0.81-1.93)]. In contrast, HA conferred a consistently significant risk for MetS, regardless of the menstrual frequency status [AOR of 1.48 for HA and eumenorrhea (95% CI 1.15-1.90)]. CONCLUSIONS Our results suggest that HA but not history of Oligo is independently associated with the risk of prevalent MetS in pre- and perimenopausal women in their 40s.

Abstract
Most research on birth weight and adult health status has reported adult measures at a single time point. This study examined the relationship of self-reported birth weight to longitudinal changes in adult body composition in 587 women of the Michigan Bone Health and Metabolism Study, followed from 1992 to 2007 and aged 24-50 years at baseline. Linear mixed models were used to estimate the association between three birth weight categories and women's 15-year changes in adult weight, height, BMI, waist and hip circumference, waist-to-hip ratio, and fat, lean, and skeletal muscle mass. Body composition measures increased in all women over the 15-year study period. At their adult baseline, high birth weight women weighed 13% more and had waist circumference and lean mass measures that were 5.51 cm and 3.91 kg larger, respectively, than normal birth weight women. No differences were observed in adult body composition between low and normal birth weight women and rates of change in the adult measures did not vary across the birth weight groups. Women heavier at birth continued to be heavier through adulthood, corroborating previous reports based on single measures of adult body composition. Research to address whether higher adult body composition in high birth weight women increases the longitudinal risk for obesity-related chronic diseases is needed.

Abstract
OBJECTIVES To investigate whether lipid accumulation product (LAP) is related to androgen and sex hormone binding globulin (SHBG) levels and to cardiovascular risk factors in postmenopausal women with no evidence of established cardiovascular disease. STUDY DESIGN Cross-sectional study. MAIN OUTCOME MEASURES LAP (waist-58 × triglycerides [nmol/L]), LAP ≥ arbitrary cutoff point of 34.5, serum testosterone, SHBG, ultrasensitive C-reactive protein (us-CRP). RESULTS Forty-nine women (mean age 55±5 years; median amenorrhea time 5.5 years [3-8]) were studied: 14% had the metabolic syndrome and 24.5% were hypertensive. Compared with LAP<34.5, LAP ≥ 34.5 (n=29, 59%) was associated with higher testosterone (p=0.021) and free androgen index (FAI) (p=0.003) and lower SHBG levels (p=0.013). Us-CRP (p=0.012), total cholesterol (p=0.041), glucose (p=0.020) and homeostasis model assessment (HOMA) (p=0.019) were higher, and high-density lipoprotein cholesterol (HDL-C) (p=0.001) was lower with LAP ≥ 34.5. LAP was positively correlated with total testosterone (r=0.349, p=0.014), FAI (rs=0.470, p=0.001), us-CRP (r=0.315, p=0.042), systolic (r=0.318, p=0.028) and diastolic (r=0.327, p=0.023) blood pressure, total cholesterol (r=0.498, p<0.001) and glucose (rs=0.319, p=0.026). LAP was negatively correlated with SHBG (rs=-0.430, p=0.003) and HDL-C (r=-0.319, p=0.026). CONCLUSIONS LAP index seems to be associated with androgens and SHBG and with cardiovascular risk factors in postmenopausal women. Also, LAP seems to be a suitable method to screen for cardiovascular risk in postmenopause.

Abstract
OBJECTIVE To assess body weight composition in postmenopausal women and determine correlations with metabolic and hormonal parameters. METHODS Medical records of 574 postmenopausal Caucasian Spanish women first time attending a menopause clinic were retrospectively reviewed. Retrieved information included general demographic data, type of menopause, time since menopause onset and baseline hormonal and metabolic parameters. A body mass index (BMI) value of >28.8 kg/m(2) was used to define obesity. The metabolic syndrome (METS) was diagnosed with three or more criteria: fasting glycemia ≥ 100 mg/dL, high density lipoprotein cholesterol (HDL-C) <50 mg/dL, triglycerides (TG) ≥ 150 mg/dL, blood pressure ≥ 130/85 mmHg and obesity (as defined above). RESULTS Mean age of the whole cohort was 49.9 ± 6.1 years, with 66% having a natural menopause. A 38.9% and 23.1% of all women were obese or had the METS, respectively. Obese women were older, had a higher parity, smoked less, had more time since menopause onset and a higher rate of surgical menopause as compared to non-obese ones (p = 0.001). BMI values positively correlated with age, time since menopause, parity, and glucose, TG and systolic blood pressure levels; displaying an inverse correlation with HDL-C and SHBG levels. SHBG levels inversely correlated with glucose, TG, HDL-C and systolic blood pressure levels. CONCLUSION In this Spanish postmenopausal population BMI significantly increased with age, time since menopause and parity displaying significant correlations with hormonal and metabolic parameters.

Abstract
BACKGROUND Effects of androgens on follicle maturation have been controversial for some time. Here, we review the potential of their applications in improving human ovulation induction, based on human and animal data, reported in the literature. METHODS We reviewed the published literature for the years 2005-2011, using relevant key words, in PubMed, Medline and Cochrane reviews, and then performed secondary reviews of referenced articles, which previously had not been known or preceded the searched time period. A total of 217 publications were reviewed. RESULTS Contrary to widely held opinion, recent data, mostly developed in the mouse, convincingly demonstrate essential contribution of androgens to normal follicle maturation and, therefore, female fertility. Androgens appear most engaged at preantral and antral stages, primarily affect granulosa cells, and exert effects via androgen receptors (AR) through transcriptional regulation but also in non-genomic ways, with ligand-activated AR modulating follicle stimulating hormone (FSH) activity in granulosa cells. While some androgens, like testosterone (T) and dehydroepiandrosterone (DHEA), appear effective in improving functional ovarian reserve (FOR) in women with diminished ovarian reserve (DOR), others may even exert opposite effects. Such differences in androgens may, at least partially, reflect different levels of agonism to AR. DISCUSSION Selective androgens appear capable of improving early stages of folliculogenesis. They, therefore, may represent forerunners of a completely new class of ovulation-inducing medications, which, in contrast to gonadotropins, affect follicle maturation at much earlier stages.

Abstract
During the 20th century there were clear indications that the socio-cultural suppression of women's sexuality had lessened, revealing a marked variability of women's sexual expression. In this article we review the recent literature to explore explanations for this variability. It is clear that we know little about the nature of sexual desire, and in particular, what it is that is desired. There is also now substantial evidence that vaginal response, as measured by vaginal pulse amplitude, is a relatively automatic response to perception of sexual stimuli, regardless of whether these stimuli are perceived positively or result in subjective arousal. This is considered as a possible mechanism that allows vaginal intercourse without pain, even when the woman is not sexually aroused. The roles of androgens and estrogen in women's sexuality remain uncertain. The evidence is, however, consistent with there being a testosterone-dependent component of women's sexuality that is more important for some women than others. Finally, a new theoretical model is presented that aims to resolve these uncertainties and that proposes different types of women's sexuality. Once we have a better understanding of "normal" female sexuality, in its various forms, our ability to develop effective treatments for women's sexual problems should improve.

Abstract
BACKGROUND In the post-Women's Health Initiative Study era few post-menopausal women complete long term hormonal treatment (HT). OBJECTIVE To analyse metabolic/hormonal parameters and frequency of the metabolic syndrome (METS) in post-menopausal women after 10 years of HT. METHODS Retrospective data from parallel cohorts of post-menopausal women receiving HT for 10 years was analysed. Regimens included: transdermal oestradiol (50 microg) (n=22), sequential cyclic HT with transdermal oestradiol (50 microg) plus 200 mg/day micronized oral progesterone (cycle days 12-25) (n=83), or continuous combined HT with transdermal oestradiol (50 microg) plus 100 mg/day micronized oral progesterone (n=46). A group of women who elected not to use HT served as a control group (n=35). RESULTS Frequency of the METS did not significantly increase after 10 years of HT. Oestradiol and sex hormone binding globulin (SHBG) levels displayed a significant increase compared to baseline after 10 years of HT (all regimens). These values were significant higher when compared to the control group. Glucose levels were significantly higher after 10 years in women receiving the sequential cyclic regimen. Although not reaching statistical significance, there was a trend for transdermal oestradiol alone to increase HDL-C and decrease triglyceride levels. CONCLUSION Serum oestradiol and SHBG levels were significantly higher after 10 years of transdermal oestradiol, alone or combined with micronized oral progesterone, without differences observed in serum metabolic parameters. More research through randomised clinical trials is required.

Abstract
OBJECTIVE Polycystic ovarian syndrome (PCOS), the most common endocrinopathy of young women, is characterized by androgen excess and is frequently associated with cardiovascular risk factors. However, it is unclear whether PCOS is a risk factor for atherosclerosis. We sought to determine in a multiethnic population-based sample whether women with PCOS have greater measures of subclinical atherosclerosis than women without PCOS. DESIGN Cross-sectional study of a nested cohort from the Dallas Heart Study (2000-2002). PARTICIPANTS Women between the ages of 35 and 49 (n = 827). PCOS was defined by Rotterdam criteria. The normal control group had regular menses, total testosterone <2·78 nmol/l, no signs of hirsutism and no polycystic ovarian morphology by magnetic resonance imaging (MRI). MEASUREMENTS Subclinical atherosclerosis defined as coronary artery calcium (CAC) by computed tomography and abdominal aortic plaque by MRI. RESULTS The prevalence of PCOS in Dallas County was 19·6% (n = 144), and 8·0% (n = 56) had both oligomenorrhea and hyperandrogenism. Women with PCOS had higher body mass index, blood pressure, insulin and leptin than regularly cycling controls. Despite a greater prevalence of cardiovascular risk factors, women with PCOS did not have a greater prevalence of CAC > 10 Agatston units (PCOS 5%, controls 6·3%, P = 0·74) or abdominal aortic plaque (PCOS 25·8%, controls 34·4%, P = 0·13) than controls. CONCLUSIONS In a large, multiethnic, population-based sample of premenopausal women, PCOS, defined by Rotterdam criteria, was not associated with a higher prevalence of coronary artery calcium or abdominal aortic plaque.

Abstract
Androgens have an important role in ovarian follicular growth and function, but circulating androgen concentrations are also associated with ovarian dysfunction, cardiovascular disease, and metabolic disorders in women. The extent and causes of the variation in androgen production in individuals, however, are unknown. Because thecal cells of follicles synthesize androstenedione and testosterone, variation in production of these androgens is hypothesized to be directly related to the inherently high variation in number of healthy growing follicles in ovaries of individuals. To test this hypothesis, we determined whether thecal CYP17A1 mRNA (codes for a cytochrome P450 enzyme involved in androgen synthesis), LH-induced thecal androstenedione production, androstenedione concentrations in follicular fluid, and circulating testosterone concentrations were lower in cattle with relatively low versus high number of follicles growing during follicular waves and whether ovariectomy reduced serum testosterone concentrations. Results demonstrated that cattle with a low follicle number had lower (P<0.05) abundance of CYP17A1 mRNA in thecal cells, reduced (P<0.01) capacity of thecal cells to produce androstenedione in response to LH, lower (P<0.01) androstenedione concentrations in ovulatory follicles, and lower (P<0.02) circulating testosterone concentrations during estrous cycles compared with animals with high follicle number. Also, serum testosterone in cattle with low or high follicle number was reduced by 63 and 70%, respectively, following ovariectomy. In conclusion, circulating androgen concentrations are lower in cattle with low versus high number of follicles growing during follicular waves, possibly because of a reduced responsiveness of thecal cells to LH.

Abstract
CONTEXT The contribution of reproductive hormones to mood has been the focus of considerable research. Results from clinical and epidemiological studies have been inconsistent. It remains unclear whether alterations in serum hormone levels across the menopausal transition are linked to depressive symptoms. OBJECTIVES To evaluate the relationship between serum hormone levels and high depressive symptoms and whether hormone levels or their change might explain the association of menopausal status with depressive symptoms previously reported in a national sample of midlife women. DESIGN A longitudinal, community-based, multisite study of menopause. Data were collected at baseline and annually from December 1995 to January 2008 on a range of factors. Early follicular phase serum samples were assayed for levels of estradiol, follicle-stimulating hormone, testosterone, and dehydroepiandrosterone sulfate. SETTING Seven communities nationwide. PARTICIPANTS A community-based sample of 3302 multiethnic women, aged 42 to 52 years, still menstruating and not using exogenous reproductive hormones. Main Outcome Measure Depressive symptoms assessed with the Center for Epidemiological Studies Depression Scale (CES-D). The primary outcome was a CES-D score of 16 or higher. RESULTS In multivariable random-effects logistic regression models, log-transformed testosterone level was significantly positively associated with higher odds of a CES-D score of 16 or higher (odds ratio = 1.15; 95% confidence interval, 1.01-1.31) across 8 years, and a larger increase in log-transformed testosterone from baseline to each annual visit was significantly associated with increased odds of a CES-D score of 16 or higher (odds ratio = 1.23; 95% confidence interval, 1.04-1.45). Less education, being Hispanic, and vasomotor symptoms, stressful life events, and low social support at each visit were each independently associated with a CES-D score of 16 or higher. No other hormones were associated with a CES-D score of 16 or higher. Being perimenopausal or postmenopausal compared with being premenopausal remained significantly associated with a CES-D score of 16 or higher in all analyses. CONCLUSIONS Higher testosterone levels may contribute to higher depressive symptoms during the menopausal transition. This association is independent of menopausal status, which remains an independent predictor of higher depressive symptoms.

Abstract
Aging is associated with a gradual decline in circulating testosterone concentrations and decreased musculature in men. While testosterone administration is often considered when symptoms of hypogonadism are presented, the long-term effects of androgen use on muscle physiology are not yet fully understood. The definition of hypogonadism in men remains obscure but is generally indicated by total testosterone concentrations less than a threshold value of 300-500 ng/dL. Androgen replacement therapy is generally safe in men and women with low endogenous testosterone concentrations. The development of selective androgen receptor modulators (SARMs) may provide additional options in treatment of hypogonadism while lowering the potential of side effects often associated with long-term androgen use. Androgen administration, either alone or in combination with other treatments, can be successful in improving muscle mass by increasing protein anabolism and reducing protein catabolism in men and women. Further research is necessary to optimize the anabolic and anticatabolic properties of androgens for treatment and prevention of muscle loss in men and women.
