What is a consequence of inadequate production of FSH and LH in males?

• A. It can lead to increased sperm production
• B. It can lead to inadequate sperm production
• C. It has no impact on fertility
• D. It enhances testosterone levels

Answer: (B)

FSH and LH from the pituitary are essential for male fertility. LH stimulates Leydig cells to produce testosterone, which supports sperm development, while FSH acts on Sertoli cells to nurture germ cells and promote their maturation and spermiation. When production of these hormones is inadequate, Sertoli cell support and intratesticular testosterone both fall, impairing spermatogenesis. The result is reduced sperm production and potential infertility. This wouldn’t boost sperm count or testosterone levels; rather, it would lower them and impair fertility.
