Hypokalemia alters sex hormone and gonadotropin levels: evidence that FSH may be required for luteinization.

Effect of Withania somnifera (L.) Dunal on Sex Hormone and Gonadotropin Levels in Addicted Male Rats

Objective Opioid consumption has been widely increasing across the globe; however, it can cause adverse effects on the body. Morphine, an opioid, can reduce sex hormones and fertility. Withania somnifera (WS) is a traditional herb used to improve sexual activities. This study strives to investigate the effect of WS on sex hormones and gonadotropins in addicted male rats.

The Effect of Oral Feeding of Tribulus terrestris L. on Sex Hormone and Gonadotropin Levels in Addicted Male Rats

A Comparison of Outcomes from IVF Cycles Stimulated with either Recombinant Luteinizing Hormone or Human Menopausal Gonadotropins in Subjects Treated with Long Gonadotropin Releasing Hormone Agonist Protocols, a Retrospective Analysis.

Objective The objective of this study is to compare rates of pregnancy and IVF parameters in subjects who were stimulated with follicle stimulating hormone (FSH) plus either recombinant human luteinizing hormone (r-LH) or human menopausal gonadotropins (hMG), in long gonadotropin releasing hormone (GnRH) agonist IVF protocols. MaterialsAndMethods This is a cohort study of patients undergoing IV...

Expression of the gonadotropin receptors during follicular development

Background Gonadotropins induce follicular development that leads to ovulation and luteinization. In women, the level of gonadotropins, along with the expression of their receptors, changes dynamically throughout the menstrual cycle. This study aimed to clarify the mechanisms underlying these phenomena. Methods The literature was reviewed, including that published by the authors. Main findi...

P-228: Altered Expression of Folliclestimulating Hormone Receptor and Luteinizing Hormone Receptor in Granulosa Cells from Women with Polycystic Ovary Syndrome

Background: Polycystic ovary syndrome (PCOS) is a common complex genetic endocrinopathy, affecting 5 - 10% of women at reproductive age. PCO granulosa cells seem to have abnormal responses to follicle- stimulating hormone (FSH). FSH is considered to be a pituitary glycoprotein that plays an important role during folliculogenesis as it promotes the proliferation and differentiation of granulosa ...
