Question

Which one of the following functions is at- tributed to the Sertoli cells?

(A) Secretion of follicle-stimulating hormone
(B) Secretion of testosterone
(C) Secretion of androgen-binding protein
(D) Secretion of luteinizing hormone
(E) Secretion of interstitial cell stimulating hormone

Answer 1

Sertoli cells secrete androgen-binding protein (ABP), which is stimulated by the follicle-stimulating hormone (FSH) and is essential for maintaining high levels of testosterone required for spermatogenesis.

Step-by-step explanation:

One of the functions attributed to the Sertoli cells is the secretion of androgen-binding protein (ABP). The follicle-stimulating hormone (FSH) released from the pituitary gland stimulates the Sertoli cells in the testes. These cells play a critical role in spermatogenesis by nurturing the developing sperm cells. Most importantly, in response to FSH, Sertoli cells secrete ABP, which binds to testosterone, maintaining a high testosterone concentration that is crucial for the proper development of sperm.
