Gonadotrophines hypophysaires : physiologie et exploration fonctionnelle

Abstract

The pituitary gonadotropins are the luteinizing hormone (LH) and the follicle stimulating hormone (FSH). They are secreted by the gonadotrop cells. LH and FSH are regulated by many factors such as the gonadotropin releasing hormone (Gn-RH) for the up-regulation and the inhibins for the down-regulation. The action of FSH and LH is essential to reproduction in women and men as well. Recent progress is noted regarding the factors of regulation and the knowledge of gonadotrophin genetics, which provides essential keys for gonadic pathology.
