Follicle-stimulating hormone (FSH) and luteinizing hor-mone (LH) are glycoprotein hormones secreted by the 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 ). Sertoli cell number largely determines the number of germ cells ( Sharpe, 1994 ).

Web2 May 2024 · What is the role of FSH in spermatogenesis? FSH stimulates both the production of androgen binding protein (ABP) by Sertoli cells, and the formation of the blood-testis barrier. ABP is essential to concentrating testosterone in levels high enough to initiate and maintain spermatogenesis.

WebFSH stimulates the Sertoli cells to secrete androgen-binding protein into the lumen of the seminiferous tubules. Binding of testosterone in the lumen provides a local testosterone supply for the developing permatogonia. WebThe results of this study showed that DGCR8 is an important gene for the entire spermatogenesis pathway. Moreover, the DGCR8 gene plays an important role in the diagnosis of NOA subgroups, also expression changes in it might contribute to SCOS or MA phenotypes. This gene can also be a predictor of sperm retrieval.
