If spermatogenesis proceeds too rapidly, inhibin is released. Inhibin reduces the secretion of

  • Luteinising Hormone (LH)

  • Follicle Stimulating Hormone (FSH)

  • Testosterone

  • Interstitial Cell Stimulating Hormone (ICSH)

Solution

B.

Follicle Stimulating Hormone (FSH)

Spermatogenesis is initiated due to an increase in the secretion of Gonadotropin Releasing Hormone (GnRH) by the hypothalamus at the age of puberty. Increase in the levels of GnRH acts on the anterior pituitary and stimulate the secretions of two gonadotropin, i.e., Luteinising Hormone (LH) and Follicle Stimulating Hormone (FSH). 

When spermatogenesis proceeds too rapidly in males, another hormone called inhibin is secreted from the Sertoli cells. Which has a negative feedback property which inhibits the secretion of FSH from anterior pituitary.
