Significantly lower luteinizing hormone (LH) and follicle stimulating hormone (FSH) basal values as well as responses to LH releasing hormone (LH-RH) were observed in 8 normal women under combination oral contraceptives. Conversely, in 7 women taking sequential oral contraceptives, basal LH and FSH remained within the normal range. The LH-FSH responses were increased and delayed when the tests were performed during the period of estrogen treatment. Thus, with combination oral contraceptives, constant high levels of estrogens and progesterone inhibit the LH peak and also decrease the basal LH-FSH levels and responses to the releasing hormone, while with sequential drugs the low level of estradiol does not inhibit such responses and even enhances them. In menopausal women, both basal and gonadotropin responses to LH-RH were increased, indicating a considerable pituitary reserve. In menstruating women, a significant estradiol increase is observed 2 and 4 hours after a 100 mcg injection of LH-RH both during the follicular and the luteal phases, whereas progesterone increases only in the luteal phase. In men, testosterone was found to increase 4 hours after a 100 mcg injection of LH-RH. The findings show that in normal subjects sex steroid hormones are important regulators of the sensitivity of the pituitary response to the releasing hormone.
