Question

Which hormone secreted by the hypothalamus initiates spermatogenesis at puberty?

Options

• Gonadotropin Releasing Hormone (GnRH)

• Luteinizing Hormone (LH)

• Follicle Stimulating Hormone (FSH)

• Testosterone

Answer 1

Spermatogenesis begins at puberty due to a significant rise in Gonadotropin Releasing Hormone (GnRH) secretion by the hypothalamus. This increase in GnRH triggers the initiation and continuation of the process of male gamete formation, which continues throughout life though it gradually declines in old age.
