Question

The process of spermatogenesis and oogenesis in most vertebrates are under the influence of which of the following hormones?

• A. Oxytocin
• B. FSH and LH
• C. ACTH
• D. ICSH

Answer 1

Answer: (B)

FSH and LH

In human males, GnRH stimulates the secretion of a hormone (LH) and a follicle-stimulating hormone (FSH). LH stimulates the Leydig cells for the secretion of androgens which in turn stimulate the process of spermatogenesis. FSH stimulates the Sertoli cells for spermiogenesis. In human females, the secretion of gonadotropins (LH and FSH) stimulates follicular development, as well as secretion of estrogens by the growing follicles. The LH surge induces rupture of Graafian follicle and the release of an ovum (ovulation). Thus, the correct answer is option B.
