What is the role of FSH in the process of spermatogenesis?
Options
- AInhibit the synthesis and secretion of androgens
- BActs on the Sertoli cells
- CInhibit secretion of factors which help in the process of spermiogenesis
- DNone of the above
Correct answer
B. Acts on the Sertoli cells
Step-by-step solution
Spermatogenesis starts at the age of puberty due to significant increase in the secretion of gonadotropin releasing hormone (GnRH). This, if you recall, is a hypothalamic hormone. The increased levels of GnRH then acts at the anterior pituitary gland and stimulates secretion of two gonadotropins – luteinising hormone (LH) and follicle stimulating hormone (FSH). LH acts at the Leydig cells and stimulates synthesis and secretion of androgens. Androgens, in turn, stimulate the process of spermatogenesis. FSH acts on t
