Identify the correct option (A), (B), (C), (D) with respect to spermatogenesis. [figure]
- FSH, Leydig cells, Sertoli cells, spermiogenesis.
- ICSH, Interstitial cells, Leydig cells, spermiogenesis.
- FSH, Sertoli cells, Leydig cells, spermatogenesis.
- ICSH, Leydig cells, Sertoli cells, spermatogenesis.
Answer
(1) FSH, Leydig cells, Sertoli cells, spermiogenesis.
Solution
GnRH from the hypothalamus stimulates the anterior pituitary to secrete LH and FSH, so (A) = FSH.
LH acts on the Leydig cells, (B) = Leydig cells, which secrete androgens that stimulate spermatogenesis (formation of spermatids).
FSH acts on the Sertoli cells, (C) = Sertoli cells, which secrete factors that help in spermiogenesis, (D) = spermiogenesis.
Answer: (1)
