New York, New York 10021 Five premenarchial rhesus monkeys were treated with human menopausal gonadotropin (HMG)
and chorionic gonadotropin (HCG) to induce ovulation. All animals had large elevations in serum
estradiol concentrations and perineal sex skin development in response to HMG injections. Four of
five monkeys had peripheral progesterone concentrations suggestive of ovulation after HCG
administration and corpora lutea were confirmed histologically in two animals. Thus, ovaries of
reproductively immature monkeys are capable of steroid secretion and ovulation when provided
with sufficient gonadotropin stimulation.
