Background Low testosterone levels have been associated with coronary heart disease (CHD) morbidity and mortality in men, but the influence of hormones in postmenopausal women is unclear. This meta-analysis aimed to examine whether there is an association between endogenous sex hormones and CHD risk in postmenopausal women. Methods A systematic search of the PubMed and EMBASE databases from 1966 to 30 November 2016 was performed for prospective studies that reported an association between endogenous sex hormones and CHD in postmenopausal women...

OBJECTIVES: To investigate the effects of a combined oral contraceptive (COC) containing 17β-estradiol (E2) 1.5 mg and nomegestrol acetate 2.5 mg (NOMAC/E2) on the sexual health of women affected by low sexual desire due to COCs containing ethinylestradiol. MATERIALS AND METHODS: Eighty-three women (age range 19-32) participated in the study. Sex hormone-binding globulin (SHBG), total testosterone (TT), and free androgen index (FAI) were measured. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively...

The presence of nonalcoholic fatty liver disease (NAFLD) is a strong risk predictor for type 2 diabetes (T2D). A reduction in sex hormone-binding globulin (SHBG) is associated with NAFLD. Low SHBG is also associated with insulin resistance (IR). However, very limited data are available for the association of SHBG and IR in patients with NAFLD. The study aims to clarify the association between SHBG and IR in patients with NAFLD. In this cross-sectional study, 334 men with NAFLD were recruited. SHBG, total testosterone, free testosterone, total cholesterol, triglyceride, insulin, and glucose concentrations were measured...

INTRODUCTION: Diabetic men with erectile dysfunction have not been widely studied. They have low testosterone levels, causing low sex drive and erectile dysfunction. AIM: To assess the erectile dysfunction and sex drive in relation to testosterone serum levels in type 2 Diabetes Mellitus (DM) patients. MATERIALS AND METHODS: A total of 64 patients with type 2 DM were enrolled in this cross-sectional study, according to the treatment types they were divided into three groups, group (A): 34 patients treated with metformin, group (B): 30 patients treated with sulfonylurea and group (C): 27 healthy normal non-diabetic men are taken as control...

1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane (DBE-DBCH - formerly TBECH) is an emerging brominated flame retardant (BFR) pollutant with androgen potentiating ability and other endocrine disrupting effects in birds and fish. The objectives of this study were to determine the effects of exposure to environmentally-relevant levels of DBE-DBCH on circulating levels of thyroid and sex steroid hormones in American kestrels, and if hormonal concentrations were related to previously reported changes in reproductive success and courtship behaviors...

INTRODUCTION: The female sexual response is complex and influenced by several biological, psychological, and social factors. Testosterone is believed to modulate a woman's sexual response and desire, because low levels are considered a risk factor for impaired sexual function, but previous studies have been inconclusive. AIM: To investigate how androgen levels and psychosocial factors are associated with female sexual dysfunction (FSD), including hypoactive sexual desire disorder (HSDD)...

Female sexual dysfunction (FSD) is a public health problem that affects women's quality of life. Although the relationship between some hormones and the FSD has been described, it is not well established for all hormones. Therefore, the aim of our study was to evaluate the association between hormonal dysfunction and sexual dysfunction in premenopausal women. We performed a cross-sectional study with 60 patients with regular menstrual cycles, with age ranging from 18 to 44 years, with previous diagnosis of FSD...

Background: Low testosterone levels are a common finding among men with Type 2 Diabetes Mellitus (T2DM) and are inversely related to insulin resistance. Whether this relationship holds true in patients with hypertension, but normal glucose tolerance or prediabetes, is unclear. Methods: We recruited 87 male outpatients with essential arterial hypertension, aged 35-70 years. Anthropometric data were collected, an Oral Glucose Tolerance Test (OGTT) performed, and the homeostasis model assessment of insulin resistance (HOMA-IR) score calculated...

BACKGROUND: The hypothalamic-pituitary-gonadal axis is transiently activated during the postnatal months in boys, a phenomenon termed "minipuberty" of infancy, when serum testosterone (T) increases to pubertal levels. Despite high circulating T there are no signs of virilization. We hypothesize that free T as measured in saliva is low, which would explain the absence of virilization. METHODS: We measured serum total T and free T in saliva using liquid chromatography-tandem mass spectrometry (LC-MS/MS) in 30 infant boys, aged 1-6 months, and in 12 adolescents, aged 11-17 years...

OBJECTIVE: Metformin has been used as a treatment option for polycystic ovary syndrome (PCOS) since 1994; however, more than a hundred randomized clinical trials have reported controversial results regarding the efficacy of metformin in PCOS. This could be due to the small sample size and high variability in methodology between studies. The objective of the present meta-analysis was to determine the effect of metformin on clinical, metabolic, and endocrine outcomes compared to placebo in PCOS women...

OBJECTIVE: We compared sex steroid levels of postmenopausal patients with symptomatic pelvic organ prolapse (POP) with postmenopausal matched patients without any sign of POP. Furthermore, we evaluated a possible relationship between sex steroid levels and various urogynecologic parameters in cases with POP. Main outcome of interest were differences in circulating estradiol levels between the two groups. STUDY DESIGN: We conducted a case-control study and 46 postmenopausal women with symptomatic POP≥stage 2 were matched 1:1 with 46 urogynecologic healthy women...

INTRODUCTION: 25-hydroxyvitamin D [25(OH)D] deficiency has been associated with low testosterone levels in men, but there are conflicting reports of its associations with sex hormones in women. Less is known about whether these associations are independent of adiposity and lifestyle factors, and whether they differ by race/ethnicity. AIM: To examine associations of 25(OH)D concentrations with sex hormone levels. METHODS: Cross-sectional analysis of 3017 men and 2929 women in a multi-ethnic cohort...

Historically, higher levels of serum testosterone were presumed deleterious to the cardiovascular system. In the last two decades, studies have suggested that low testosterone levels are associated with increased prevalence of risk factors for cardiovascular disease (CVD), including dyslipidemia and diabetes. This is a cross sectional study. The aim of our study was to determine the relationship between serum testosterone levels and angiographic severity of coronary artery disease (CAD). Serum testosterone levels were also correlated with flow mediated dilation of brachial artery (BAFMD) - an indicator of endothelial function...

BACKGROUND: Abiraterone acetate, approved for patients with metastatic castration-resistant prostate cancer (mCRPC), blocks androgen byosinthesis. We aimed to describe changes determined by abiraterone in hormones implied in steroid biosynthesis, exploring association between hormonal levels and drug activity. METHODS: Patients with mCRPC, receiving standard abiraterone + prednisone after docetaxel failure, were studied. We determined serum levels of progesterone, 17OH-progesterone, cortisol, ACTH, DHEA-sulphate, androstenedione, testosterone, sex hormone-binding globulin, aldosterone, plasma renin activity, and cholesterol, baseline and every 12 weeks...

STUDY QUESTION: How well does multi-analyte steroid mass spectrometry (MS) profiling classify women with and without polycystic ovary syndrome (PCOS)? SUMMARY ANSWER: Our liquid chromatography MS (LC-MS) steroid profiling only minimally improves discrimination of women with and without PCOS compared with a direct testosterone immunoassay (T_IA) and the free androgen index (FAI). WHAT IS KNOWN ALREADY: Blood testosterone measured by direct (non-extraction) immunoassay overlaps between women with and without PCOS...
