Context: Androgen excess in women is predominantly due to underlying polycystic ovary syndrome (PCOS). However there is a lack of clarity regarding patterns and severity of androgen excess that should be considered predictive of non-PCOS pathology. Objective: We examined the diagnostic utility of simultaneous measurement of serum dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4) and testosterone (T) to delineate biochemical signatures and cut-offs predictive of non-PCOS disorders in women with androgen excess...

The French endocrinology society (SFE) and the French pediatric endocrinology society (DFSDP) have drawn up recommendations for the management of primary and secondary adrenal insufficiency in the adult and child, based on an analysis of the literature by 19 experts in 6 work-groups. A diagnosis of adrenal insufficiency should be suspected in the presence of a number of non-specific symptoms except hyperpigmentation which is observed in primary adrenal insufficiency. Diagnosis rely on plasma cortisol and ACTH measurement at 8am and/or the cortisol increase after synacthen administration...

OBJECTIVE: To examine the relationship between endogenous sex steroids and various condition-specific quality of life domains in postmenopausal women with pelvic floor disorders. We hypothesized that woman with lowest androgen and estradiol concentrations would report worse scores of quality of life domains. METHODS: Forty-six women with pelvic organ prolapse (POP) and 47 cases with stress urinary incontinence (SUI) answered the validated pelvic floor questionnaire and underwent serum sex steroid measurement...

Neuroactive steroids, including testosterone, dehydroepiandrosterone (DHEA) and its sulfate (DHEA-S) might play an important role in the pathophysiology of schizophrenia. Therefore, we performed a systematic review and meta-analysis of studies comparing the levels of testosterone, DHEA and DHEA-S in patients with schizophrenia and healthy controls. We searched electronic databases from their inception until Oct 29, 2017. Effect size (ES) estimates were calculated as Hedges' g. Data analysis was performed using random-effects models...

OBJECTIVE: Despite the increased risk for cardiovascular morbidity associated with vital exhaustion (VE), the underlying pathophysiological mechanisms remain unclear. Allostatic load may constitute the missing link between VE and cardiovascular diseases. The aim of the present study was to investigate whether men with different degrees of VE would differ in terms of allostatic load, chronic stress, and social support. METHODS: The Men Stress 40+ study sample consisted of N=121 apparently healthy men aged 40 to 75years...

Prior research suggests that several endogenous hormones in premenopausal women are associated with breast cancer risk; however, few studies have evaluated associations of endogenous hormones with mammographic density (MD) in premenopausal women. We conducted a cross-sectional study of plasma hormone levels in relation to MD among 634 cancer-free premenopausal women in the Nurses' Health Study II. We measured percent MD from screening mammograms using a computer-assisted method. We assayed estradiol, estrone, and estrone sulfate in blood samples timed in early follicular and mid-luteal phases of the menstrual cycle as well as testosterone, androstenedione, progesterone, dehydroepiandrosterone (DHEA), DHEA sulfate, sex hormone-binding globulin (SHBG), and anti-Müllerian hormone in luteal or untimed samples...

Background: Elevated body mass index (BMI) is associated with increased risk of postmenopausal breast cancer. The underlying mechanisms, however, remain elusive. Methods: In a nested case-control study of 621 postmenopausal breast cancer case participants and 621 matched control participants, we measured 617 metabolites in prediagnostic serum. We calculated partial Pearson correlations between metabolites and BMI, and then evaluated BMI-associated metabolites (Bonferroni-corrected α level for 617 statistical tests = P < 8...

Adrenarche is when a child's adrenal cortex starts to secrete adrenal androgen precursors. Dehydroepiandrosterone (DHEA) is the most abundant product of the adrenal cortex, and is a weak androgen agonist thought to be responsible for the clinical signs of pubarche by conversion to more potent androgens, testosterone, and dihydrotestosterone. DHEA's extra-adrenal sulfation product, dehydroepiandrosterone sulfate, is a stable marker for adrenal androgenic activity. Pubarche is the physical manifestation of androgenic hormone production, and includes the development of pubic and axillary hair, adult body odor, and acne...

BACKGROUND: Dehydroepiandrosterone (DHEA) figures on the World Anti-Doping Agency list of prohibited substances in sport because it is assumed that athletes expect a significant increase in testosterone through DHEA administration. The literature on the hormonal effects of DHEA intake nevertheless appears to be very scant in healthy young subjects, especially women. PURPOSE: We examined the effects of DHEA on adrenal and gonadal hormones, IGF1 and free T3 in healthy young male and female recreationally trained volunteers...

17ɑ-hydroxylase deficiency (17OHD) is a rare variant of congenital adrenal hyperplasia (CAH) due to mutations in the CYP17A1 gene.1, 2 This gene encodes an enzyme that expresses both 17α-hydroxylase and 17,20-lyase activities affecting both adrenal and gonadal sex steroid production.1 Due to the location of the enzyme in the steroidogenic pathway impairment results in elevated corticosterone, deoxycorticosterone and progesterone together with low levels of cortisol, 11-deoxycortisol, dehydroepiandrosterone sulphate (DHEAS) and 17-hydroxyprogesterone...

Lean body mass (LM) has been positively associated with bone mineral density (BMD) in children and adolescents, but the relationship between body fat mass (FM) and BMD remains controversial. Several biomarkers secreted by adipose tissue, skeletal muscle, or bone may affect bone metabolism and BMD. We investigated the associations of LM, FM, and such biomarkers with BMD in children. We studied a population sample of 472 prepubertal Finnish children (227 girls, 245 boys) aged 6-8years. We assessed BMD, LM, and FM using whole-body dual-energy x-ray absorptiometry and analysed several biomarkers from fasting blood samples...

BACKGROUND: A recent report described a new PCOS-like phenotype in lean older infertile women, and was characterized by high age-specific anti-Müllerian hormone (AMH) but hypo- rather than the expected hyper-androgenism. The hypo-androgenism was, furthermore, characterized of, likely, adrenal origin and autoimmune etiology. PATIENTS AND METHODS: We extracted data on 708 consecutive infertility patients, and separated them into three age-strata, <35, 36-42, and >42 years...
