What is the main role of follicle-stimulating hormone in the male reproductive system?
Correct answer: B. It supports sperm production through Sertoli cells
- A. It stimulates testosterone release from Leydig cells
- B. It supports sperm production through Sertoli cells
- C. It causes ejaculation by contracting the vas deferens
- D. It promotes prostate growth after puberty
Explanation
FSH acts mainly on Sertoli cells in the seminiferous tubules and supports spermatogenesis. LH, rather than FSH, stimulates Leydig cells to produce testosterone, while ejaculation depends mainly on autonomic muscle contraction.

About Reproductive System
The reproductive system covers the male and female reproductive organs, gamete formation, the menstrual and ovarian cycles, fertilization, implantation and pregnancy. It explains the roles of FSH, LH, oestrogen, progesterone and testosterone, while distinguishing spermatogenesis from oogenesis and the reproductive organs from the accessory glands.
