[Hyperandrogenism after menopause: Ovarian or adrenal origin?]

Gynecol Obstet Fertil Senol 2022 May 21. Epub 2022 May 21.

Service d'endocrinologie, hôpital Saint-Antoine, 184, rue du faubourg Saint-Antoine, 75012 Paris, France; Sorbonne Université, Paris, France.

Postmenopausal hyperandrogenism is an androgen excess originating from either the adrenals and/or the ovaries. Clinically, symptoms can be moderate (increase in terminal hair growth, acnea) or severe with signs of virilization (alopecia, clitoridomegaly). In either setting, physicians need to exclude relatively rare but potentially life-threatening underlying tumorous causes, such as adrenal androgen-secreting tumors. Read More

Aromatase Inhibition Eliminates Sexual Receptivity Without Enhancing Weight Gain in Ovariectomized Marmoset Monkeys.

J Endocr Soc 2022 Jun 22;6(6):bvac063. Epub 2022 Apr 22.

Wisconsin National Primate Research Center, University of Wisconsin-Madison, Madison, WI 53715, USA.

Context: Ovarian estradiol supports female sexual behavior and metabolic function. While ovariectomy (OVX) in rodents abolishes sexual behavior and enables obesity, OVX in nonhuman primates decreases, but does not abolish, sexual behavior, and inconsistently alters weight gain.

Objective: We hypothesize that extra-ovarian estradiol provides key support for both functions, and to test this idea, we employed aromatase inhibition to eliminate extra-ovarian estradiol biosynthesis and diet-induced obesity to enhance weight gain. Read More

Androgenic steroids dysregulation and the risk of coronary artery disease.

Expert Rev Cardiovasc Ther 2022 May 19;20(5):343-349. Epub 2022 May 19.

Department of Internal Medicine, Ochsner Health System, New Orleans, LA, US.

Introduction: Endogenous testosterone deficiency or excess anabolic-androgenic steroids (AAS) have been linked to alter the physiology of different organs in the body, more specifically, the vasculature of coronary arteries. Despite the health-related concerns of using synthetic testosterone derivatives, such as AAS, there has been a tremendous increase in the use of AAS among athletes and bodybuilders.

Areas Covered: We have highlighted the three main mechanisms that AAS increase the risk of coronary artery disease (CAD): altering the homeostasis of lipid metabolism which results in dyslipidemia and subsequently atherosclerosis, disturbing the function of platelet which results in platelet aggregation and subsequent thrombosis, and increasing the risk of coronary vasospasm by affecting the physiological function of vascular bed.

Polycystic Ovary Syndrome and the Neuroendocrine Consequences of Androgen Excess.

Compr Physiol 2022 03 29;12(2):3347-3369. Epub 2022 Mar 29.

Centre for Neuroendocrinology, Department of Physiology, School of Biomedical Sciences, University of Otago, Dunedin, New Zealand.

Polycystic ovary syndrome (PCOS) is a major endocrine disorder strongly associated with androgen excess and frequently leading to female infertility. Although classically considered an ovarian disease, altered neuroendocrine control of gonadotropin-releasing hormone (GnRH) neurons in the brain and abnormal gonadotropin secretion may underpin PCOS presentation. Defective regulation of GnRH pulse generation in PCOS promotes high luteinizing hormone (LH) pulsatile secretion, which in turn overstimulates ovarian androgen production. Read More
