Question

Which of the following cells produce factors that help in maturation of spermatids to spermatozoa?

• A. Leydig cells
• B. Sertoli cells
• C. Spermatogonia
• D. Both $\left(A\right)$ and $\left(B\right)$

Answer 1

Answer: (B)

Sertoli cells of a seminiferous tubule of testis secrete inhibin, a proteinaceous hormone, when sperm count is too high. This hormone causes negative feedback to suppress the overactivity of the FSH hormone to suppress spermatogenesis.
Also, FSH acts on the sertoli cells and stimulates the secretion of some factors which help in the process of spermiogenesis.
