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...

REVIEW
Megan Crawford, Laurence Kennedy
Crosstalk among hormones characterizes endocrine function, and assessment of the hypogonadal man should take that into consideration. In men for whom testosterone deficiency is a concern, initial evaluation should include a thorough history and physical exam in which other endocrinopathies are being considered. Hypogonadism can be associated with both pituitary and thyroid dysfunction, for which appropriate biochemical evaluation should be undertaken in certain clinical scenarios. If low serum testosterone is confirmed measurement of luteinizing and follicle stimulating hormones (LH and FSH respectively) is essential to establish whether the hypogonadism is primary or secondary...

REVIEW
Andrew J Davidiuk, Gregory A Broderick
Testosterone deficiency (TD) has become a growing concern in the field of men's sexual health, with an increasing number of men presenting for evaluation of this condition. Given the increasing demand for testosterone replacement therapy (TRT), a panel of experts met in August of 2015 to discuss the treatment of men who present for evaluation in the setting of low or normal gonadotropin levels and the associated signs and symptoms of hypogonadism. This constellation of factors can be associated with elements of both primary and secondary hypogonadism...

BACKGROUND: The associations between serum vitamin D (VD), serum testosterone (TT) and metabolic syndrome are complex and with limited published research, particularly on the effects of VD treatment on sexual hormones, erectile function and the metabolic syndrome. OBJECTIVES: This study assessed whether a monthly high dose VD treatment for 12 months in VD deficient middle-aged men was associated with: changes in levels of sexual hormones, improvement of diabetes control and metabolic syndrome components, better erectile function [International Index of Erectile Function (IIEF)-5 questionnaire]; and changes in a prostate marker...

BACKGROUND: The influence of weight loss treatment on sex hormones profile has been studied mainly in women with polycystic ovary syndrome (PCOS), but in obese premenopausal women without PCOS it still remains unclear. The aim of the study was to evaluate the effect of two approaches to obesity treatment on the serum level of sex hormones in obese women of child-bearing age without PCOS. METHODS: 77 obese Caucasian women (aged 31.2 ±8.3 years) were randomized into two groups: 39 women received a low-calorie diet (LC) and 38 received an isocaloric diet plus metformin (IM), for 12 weeks...

We present a case report of an atypical giant pituitary adenoma secreting follicle-stimulating hormone (FSH). A 55-year-old patient presented for erectile dysfunction, loss of libido and fatigue. The biochemical evaluation showed very high FSH serum levels in the presence of central hypogonadism. Neither testicular enlargement nor increased sperm count was observed, thus a secretion of FSH with reduced biological activity was supposed. The histological examination after neuro-surgery showed an atypical pituitary adenoma with FSH-positive cells...

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, endocrine outcomes as compared to placebo in PCOS women...

Objectives: Insulin resistance (IR) is a common manifestation in patients with polycystic ovarian syndrome (PCOS). Both clinical observations and animal studies have demonstrated that IR could be induced by hyperandrogenemia, which is the charac-teristic of PCOS.Nevertheless, the mechanisms of IR in PCOS are still unclear especially at the molecular level.We conduct this study to ellucidate the effects of androgen on insulin sensitivity and chronic low-grade inflammation in adult C57BL/6 female mice. Methods: Eleven adult female C57BL/6 mice aged 8 weeks weredaily injected with testosterone (1...

INTRODUCTION: Androgen deprivation therapy (ADT) is a mainstay of treatment against advanced prostate cancer (PC). As a treatment goal, suppression of plasma testosterone levels to <50 ng/dl has been established over decades. Evidence is growing though that suppression to even lower levels may add further clinical benefit. Therefore, we undertook a pooled retrospective analysis on the efficacy of 1-, 3-, and 6-month sustained-release (SR) formulations of the gonadotropin-releasing hormone (GnRH) agonist triptorelin to suppress serum testosterone concentrations beyond current standards...

BACKGROUND: Obese men commonly have reductions in circulating testosterone and report symptoms consistent with androgen deficiency. We hypothesized that testosterone treatment improves constitutional and sexual symptoms over and above the effects of weight loss alone. METHODS: We conducted a pre-specified analysis of a randomized double-blind, placebo-controlled trial at a tertiary referral centre. 100 obese men (BMI>30 kg/m(2)) with a repeated total testosterone level <12 nmol/l and a median age of 53 years (interquartile range 47-60) receiving 10 weeks of a very low energy diet (VLED) followed by 46 weeks of weight maintenance were randomly assigned at baseline to 56 weeks of intramuscular testosterone undecanoate (n=49, cases) or matching placebo (n=51, controls)...

Lactose intolerance is characterized by low or inexistent levels of lactase, and the main treatment consists of dietary changes, especially replacing dairy milk by soy milk. Soy contains phytoestrogens, substances with known estrogenic activity, besides, glyphosate-based herbicides are extensively used in soy crops, being frequently a residue in soy beans, bringing to a concern regarding the consumption of soy-based products, especially for children in breastfeeding period with lactose intolerance. This study evaluated the pubertal toxicity of a soy milk rich feeding (supplemented or not with glyphosate, doses of 50 and 100 mg/kg) during prepubertal period in male rats...

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...

Treatment to induce puberty in boys is indicated in those who do not undergo spontaneous development at a normal age. Stimulating development of the secondary sex characteristics is possible using gradually increasing doses of testosterone esters (TEs) via intramuscular (IM) administration, which is the most widely used method of testosterone (T) supplementation. When TEs are administered as monthly injection, serum T levels exhibit large fluctuations with supraphysiologic levels seen immediately after the injection followed by a decrease into the low range...

BACKGROUND: Low serum testosterone (low T) has been repeatedly linked to worse outcomes in men with newly diagnosed prostate cancer (PC). How low T contributes to these outcomes is unknown. Here we demonstrate that exposure to low T causes significant changes in the mouse prostate and prostate stem cells. METHODS: Mice were castrated and implanted with capsules to achieve castrate, normal, or sub-physiological levels of T. After 6 weeks of treatment, LC-MS/MS was used to quantify the levels of T and dihydrotestosterone (DHT) in serum and prostate tissue...
