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 protein hormone secreted by the gonads (ovaries and testes) that specifically inhibits the secretion of follicle-stimulating hormone (FSH) from the anterior pituitary gland. Therefore, the reduction of FSH secretion is caused by inhibin.
