OBJECTIVE To determine if insulin or glucose action plays a role in adrenocortical steroidogenesis in the polycystic ovary syndrome (PCOS). DESIGN Prospective cohort study. SETTING Academic medical center. PATIENT(S) Nine reproductive-aged patients with PCOS and nine age-, race-, and body mass index-matched controls. MAIN OUTCOME MEASURE(S) Insulin-modified frequently sampled intravenou...

The present investigation was designed to provide the first empirical examination of the effects of acute dehydroepiandrosterone (DHEA) administration on subjective and physiological sexual arousal in women. The primary purpose was to assess whether DHEA influences vaginal blood flow response in sexually functional women. Subjective (self-report) and physiological (vaginal photoplethysmograph) ...

BACKGROUND Inhaled corticosteroids (ICS) are the first-line therapy in the treatment of persistent asthma. At medium to high doses and prolonged usage, ICS can supresss the hypothalamic-pituitary-adrenal axis. Dehydroepiandrosterone sulphate (DHEA-S) is a corticotropin-dependent adrenal androgen precursor that is supressible in patients treated with ICS. OBJECTIVES To evaluate the adrenal axi...

OBJECTIVES To evaluate the possible effect of androgen status on sexuality and mental wellbeing in patients with primary Sjögren's syndrome (pSS). METHODS Serum levels of dehydroepiandrosterone sulphate (DHEA-S), testosterone (T), androstenedione, sex hormone binding globulin (SHBG), and the SHBG/T ratio were measured in 21 women with pSS. Sexual life was assessed by a Swedish version of the ...

A new sample preparation method coupled to GC-MS analysis was developed and validated for quantification of sulfate esters of pregnenolone (PREG-S) and dehydroepiandrosterone (DHEA-S) in rat brain. Using a solid-phase extraction recycling protocol, the results show that little or no PREG-S and DHEA-S (<1 pmol/g) is present in rat and mouse brain. These data are in agreement with studies in whic...

Background. Although the association between human chorionic gonadotropin (hCG) and hyperandrogenism was identified more than 40 years ago, relevant questions remain unanswered. Design and Methods. We conducted a prospective, longitudinal, and controlled study in 23 women with a diagnosis of a complete hydatidiform mole (HM). Results. All participants completed the study. Before HM evacuation m...

Dehydroepiandrosterone (DHEA) possesses fat-reducing effect, while little information is available on whether DHEA regulates cell proliferation and mitochondrial function, which would, in turn, affect lipid droplet accumulation in broiler. In this study, the lipid droplet accumulation, cell proliferation, cell cycle and mitochondrial membrane potential were analysis in primary chicken hepatocyt...

Serum androgens as well as their precursors and metabolites decrease from the age of 30-40 yr in women, thus suggesting that a more physiological hormone replacement therapy at menopause should contain an androgenic compound. It is important to consider, however, that most of the androgens in women, especially after menopause, are synthesized in peripheral intracrine tissues from the inactive p...

Abstract Polycystic ovary syndrome (PCOS), an endocrine disorder that affects 10% of women worldwide. In 1990, the NIH established first consensus on diagnostic criteria for PCOS which included chronic anovulation with clinical and/or biochemical hyperandrogenism, after exclusion related disorders. Traditionally assessment hyperandrogenism serum studies total testosterone (TT), free (FT), and d...

The concentration of dehydroepiandrosterone sulfate (DHEA-S) in human plasma is higher than any other steroid. Recent evidence has suggested an inverse relationship between plasma DHEA levels and the development of coronary atherosclerosis in humans. We used the cholesterol-fed rabbit model to investigate whether DHEA feeding would diminish aortic fatty streak formation in this model. Fifteen N...
