Answer:
Spermatogenesis is stimulated by FSH acting on sertoli cells.
Explanation:
Spermatogenesis is the process by which spermatozoa grow and develop from germ cells into mature form. There are many hormones that are involved in this process and one of them is FSH (Follicle Stimulating Hormone). Another factor that play a vital role in the process are sertoli cells.
The FSH stimulates sertoli cells to release androgen-binding protein into the lumen portion of seminiferous tubules. The sertoli cells are the epithelial supporting cells that are located inside the seminiferous tubules. The sertoli cells are responsible for keeping the germ cells nourished and for extracting excess cytoplasm from newly formed spermatozoa cells just before they are released into the lumen of the seminiferous tublules.
