Question

Spermatogenesis in mammalian testes is controlled by

• A. Follicle stimulating hormones
• B. Growth hormones
• C. Luteinizing hormones
• D. Estrogens

Answer 1

The correct option is A Follicle stimulating hormones

Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. In men, the production of follicle stimulating hormone is regulated by the circulating levels of testosterone and inhibin, both produced by the testes. FSH induces Sertoli cells to secrete androgen-binding proteins (ABPs), regulated by inhibin negative feedback mechanism on the anterior pituitary. Specifically, activation of Sertoli cells by FSH sustains spermatogenesis and stimulates inhibin B secretion.

So the correct option is 'follicle stimulating hormones'.
