Regulation of reproduction via tight control of gonadotropin hormone levels. [PDF]
Mammalian reproduction is controlled by the hypothalamic-pituitary-gonadal axis. GnRH from the hypothalamus regulates synthesis and secretion of gonadotropins, LH and FSH, which then control steroidogenesis and gametogenesis. In females, serum LH and FSH

Origin and Quantitative Control of Sertoli Cells [PDF]
Sertoli cell is the"nurse"in testes that regulates germ cell proliferation and differentiation. One Sertoli cell supports a certain number of germ cells during these processes. Thus, it is the determinant of male reproductive capability. Sertoli cells originate from the primitive gonads during embryonic stage and their proliferations continue ...

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Luteinizing hormone receptor knockout mouse: What has it taught us?
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...
