Question

Quizplus · Accepted Answer

Inhibin is produced by the testes and inhibits the secretion of follicle-stimulating hormone (FSH) by the anterior pituitary gland. This helps regulate spermatogenesis by controlling the activity of Sertoli cells in the testes. Chorionic gonadotropin is produced by the placenta during pregnancy and can stimulate testosterone production in the testes. Testosterone is also produced by the testes and is necessary for male sexual development and function. Estradiol is a female sex hormone primarily produced by the ovaries, but can also be produced in small amounts by the testes. Relaxin is a hormone produced by the ovaries and placenta during pregnancy to help relax the uterus and facilitate delivery.
