The Secretion of Follicle-Stimulating Hormone from the Anterior Pituitary Gland

Question

The secretion of follicle-stimulating hormone from the anterior pituitary gland is reduced by
A) inhibin.
B) luteinizing hormone.
C) oxytocin.
D) prolactin.
E) vasopressin.

Accepted Answer

Inhibin is a hormone released by the gonads (ovaries and testes) that inhibits the secretion of follicle-stimulating hormone (FSH) from the anterior pituitary gland. This helps regulate the menstrual cycle in females and spermatogenesis in males. Therefore, choice A is the correct answer as it directly addresses the reduction of FSH secretion.
