OBJECTIVES Epidemiological studies have shown that low levels of dehydroepiandrosterone might increase the risk of developing metabolic syndrome. The aim of this study was to evaluate whether dehydroepiandrosterone supplementation in schizophrenic patients treated with olanzapine would influence the anthropometric and biochemical parameters of metabolic syndrome. METHODS Male schizophrenic pa...

STUDY QUESTION Is diminished functional ovarian reserve (DFOR) associated with low androgen levels? SUMMARY ANSWER Low androgen levels are associated with DFOR at all ages. WHAT IS KNOWN ALREADY Androgen supplementation via dehydroepiandrosterone (DHEA) has been reported to improve functional ovarian reserve (FOR); pregnancy rates in IVF cycles are associated with how well DHEA converts to ...

The research aimed to investigate the effect of dehydroepiandrosterone (DHEA) on lipid peroxidation activity and nitric oxide concentration in aorta male Wistar rats due exposure cigarette smoke. This study was a laboratory experiment using 21 that were divided into 3 groups: KN-14 (negative control is given smoke within 14 days), DHEA-1 (15 mg/kgBW + for DHEA-2 (30 days). carried out 25-45 min...

Dehydroepiandrosterone (DHEA) and androstenedione are weak androgens, which need conversion to more potent testosterone in order to enhance anabolic action. Consequences of oral dosing at 1 mg/kg on the urinary and plasma androgen profile of mare and gelding have been evaluated with an analytical method involving conjugate fractionation and selective hydrolysis, group separation, and quantitati...

STUDY QUESTION What are the effects of exposure of ovarian tissue to dehydroepiandrosterone (DHEA) supplementation in vivo? SUMMARY ANSWER DHEA exposure stimulates initiation of primordial follicles and development of gonadotrophin-responsive preantral/early antral follicles possibly mediated through promoting granulosa cell proliferation and enhancing anti-Mullerian hormone (AMH) expression....

BACKGROUND In various animal models androgens have been demonstrated to enhance follicle stimulating hormone (FSH) activity on granulosa cells during small growing follicle stages. To assess whether similar synergism may also exist in humans we investigated women on androgen (dehydroepiandrosterone, DHEA) supplementation with varying concomitant FSH exposure. METHODS In a case controlled coho...
