Follicle-stimulating hormone (FSH) and luteinizing hor-mone (LH) are glycoprotein hormones secreted by the Web26 Mar 2024 · FSH acts on the Sertoli cells of the testes in order to facilitate spermatogenesis while LH acts on Leydig cells to stimulate testosterone production. This results in impressively high intra-testicular concentrations of testosterone that are essential for sperm production and approximately ~×40 serum levels [ 16 ].

WebMale infertility contributes to 50% of all cases of infertility. The main cause is low quality and quantity of sperm. In humans, spermatogenesis starts at the beginning of puberty and lasts lifelong. It is under the control of FSH and testicular androgens, and mainly testosterone (T), and therefore requires a normal gonadotroph axis, intratesticular T production by Leydig … WebThis inhibits the release of GnRH and FSH, which will cause spermatogenesis to slow down. If the sperm count reaches 20 million/ml, the Sertoli cells cease the release of inhibin, and the sperm count increases. ... Follicle cells produce the hormone inhibin, which inhibits FSH production. LH also plays a role in the development of ova ... Web3 Dec 2004 · Genetic and pharmacological studies in rodents indicate that the primary role of FSH in spermatogenesis is stimulation of Sertoli cell proliferation during prepubertal development ( Heckert & Griswold, 2002 ).
