Disorders Caused by Mutations of the Lutropin/ Choriogonadotropin Receptor Gene

  • Andrew Shenker
Part of the Contemporary Endocrinology book series (COE, volume 6)


The human receptor for lutropin and chorionic gonadotropin (LHR) plays a key role in normal and abnormal reproductive physiology (1–3). In males lutropin luteinizing hormone (LH) regulates the development and function of Leydig cells. Testosterone secreted by the Leydig cells is obligatory for the development of male internal and external genitalia, and for the establishment of secondary sexual characteristics during puberty. In women, LH acts on the theca cells to produce androgen precursors necessary for estrogen synthesis, and on the ovarian follicles to promote ovulation, subsequent corpus luteum formation, and progesterone secretion. Chorionic gonadotropin produced by the placenta acts on the corpus luteum and promotes development of the fetal testes in the first trimester of pregnancy.
