Context: The ovaries and adrenals are sources of androgens in women. While dehydroepiandrosterone (DHEA), DHEA sulfate (DHEAS), and testosterone (T) all decline with age, these C19 steroids correlate poorly with parameters of androgen action in postmenopausal women. Objective: To comprehensively compare androgen profiles in pre- and post-menopausal women. Methods: We quantified 19 steroids, including DHEA, DHEAS, T, androstenedione (A4), and the adrenal-specific 11-oxygenated C19 steroids (11oxyandrogens) 11β-hydroxytestosterone (11OHT), 11-ketotestosterone (11KT), 11β-hydroxyandrostenedione (11OHA4) and 11-ketoandrostenedione (11KA4) using liquid chromatography-tandem mass spectrometry in morning serum obtained from 100 pre- (age 20-40 years) and 100 post-menopausal (age ≥ 60 years) women...

PURPOSE: Primary and secondary sterility have become an issue of increasing importance due to demographic and social changes in society. Data regarding the association between female androgen levels and the probability of successful conception after fertility treatment are sparse and contradictive. This study was designed to assess this clinical question. METHODS: In this retrospective single-center cohort study concentrations of androgens androstenedione, dehydroepiandrosteronsulfat (DHEAS) and testosterone (ng/ml) were investigated in the serum of patients presenting for sterility at the department of reproductive medicine of Saarland University hospital Homburg between January 2015 and December 2017...

The neuroendocrine system may affect the pathophysiology of gender differences in attention deficit/hyperactivity disorder (ADHD). This study examines whether the relationships among dehydroepiandrosterone sulfate (DHEA-S), free testosterone, or sex hormone-binding globulin (SHBG) and ADHD presentations exhibit gender differences. A total of 113 boys and 35 girls with ADHD (all drug naïve) and 46 and 26 healthy control boys and girls, respectively, were recruited. Blood samples were obtained to measure the serum levels of DHEA-S, free testosterone, and SHBG in each child...

Glutathione S-transferases (GSTs) are multifunctional phase II detoxification enzymes with primary function of glutathione conjugation of various endogenous and exogenous compounds. Teleost-specific Gstr1 in zebrafish (Danio rerio) was previously shown to have high expression in toxicologically relevant tissues and high activity towards model substrates. The aim of this study was a detailed functional characterization of zebrafish Gstr1. Molecular docking analyses were used to get novel insight into structural characteristics of Gstr1 and elucidation of the mechanistic interactions with both GSH and various Gstr1 substrates or inhibitors...

BACKGROUND: Hyperandrogenemia is more common in puberty and reproductive age, but relatively rare in postmenopausal women. Postmenopausal virilization may result from androgen-producing tumors. Androgen-secreting adrenal tumors are rare in clinical practice and are diagnosed as adrenocortical carcinoma, most of which can co-secrete androgen and cortisol. Highly elevated serum testosterone level with normal adrenal androgens such as dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS) and androstenedione is usually regarded as ovary origin...

BACKGROUND: Reduced total hours of sleep and low quality of sleep have been suggested to be associated with low levels of male hormones. Few studies have examined the association between excessive sleep and male reproductive hormones. OBJECTIVE: To investigate the association of total hours of sleep and quality of sleep with serum levels of total-, bioavailable- and free testosterone (tT, bT and fT), sex hormone binding globulin (SHBG) and dehydroepiandrosteron-sulfat (DHEAS)...

While several studies have documented an increased risk of metabolic disorders in patients with polycystic ovary syndrome (PCOS), associations between androgenic and metabolic parameters in these patients are unclear. We aimed to investigate the relationships between biochemical markers of hyperandrogenism (HA) and metabolic parameters in women with PCOS. In this systematic review and meta-analysis, a literature search was performed in the PubMed, Scopus, Google Scholar, ScienceDirect, and Web of Science from 2000 to 2018 for assessing androgenic and metabolic parameters in PCOS patients...

Laboratory tests are an integral part of clinical decision making. Therefore, measurement uncertainty comes into prominence in the context of the accuracy of the laboratory result. This study aims to investigate measurement uncertainty of 14 immunoassay analytes, to compare them with different quality goals and to utilize them in the result interpretation. Measurement uncertainties of 14 immunoassay analytes were estimated by using internal and external quality control data by using Nordtest approach. Expanded uncertainties (U) were compared with allowable total error (TEa%), permissible relative deviation in the external quality assessment (PRDEQA %) and permissible expanded uncertainty for external quality assessment (pUEQAS %)...

PURPOSE: Higher levels of circulating sex steroid hormones are associated with increased breast cancer risk, though their association with prognosis remains unclear. We evaluated the association between circulating sex hormone levels and breast cancer survival in two large cohorts. METHODS: We evaluated this association among 2073 breast cancer cases from the Nurses' Health Study (NHS) and Nurses' Health Study II (NHSII) cohorts. Women in this analysis provided a blood sample in 1989-1990 (NHS) or in 1996-1999 (NHSII) and were subsequently diagnosed with breast cancer...

Both systemic and local production contribute to the concentration of steroids measured in the brain. This idea was originally based on rodent studies and was later extended to other species including humans and birds. In quail, a widely used model in behavioral neuroendocrinology, it was demonstrated that all enzymes needed to produce sex steroids from cholesterol are expressed and active in the brain but the actual concentrations of steroids produced were never investigated. We carried out a steroid profiling in multiple brain regions and serum of sexually mature male and female quail by gas chromatography coupled to mass spectrometry...
