Gonadotropin-releasing hormone (GnRH) stimulates the ovaries and testes to increase production of estradiol and testosterone by prompting the release of LH and FSH from the pituitary gland. LH and FSH then directly affect the hormone production in these organs. Therefore, the correct answer is GnRH. ;
