Abstract
Previously, we reported that short term administration of a highly potent GnRH agonist
(GnRHa) for 1 month to patients with polycystic ovarian disease (PCO) resulted in complete
suppression of ovarian steroidogenesis without measurable effects on adrenal steroid
production. This new study was designed to evaluate the effects of long term GnRHa
administration in PCO patients with respect to their hormone secretion patterns and
clinical responses. Eight PCO patients and 10 ovulatory women with endometriosis were
treated daily with sc injections of [D-His6-(imBzl]),Pro9-NEt]GnRH (GnRHa; 100 micrograms)
for 6 months. Their results were compared to hormone values in 8 women who had undergone
bilateral oophorectomies. In response to GnRHa, PCO and ovulatory women had rises of serum
LH at 1 month, after which it gradually declined to baseline. In both groups FSH secretion
was suppressed throughout treatment. Serum estradiol, estrone, progesterone,
17-hydroxyprogesterone, androstenedione, and testosterone levels markedly decreased to
values found in oophorectomized women by 1 month and remained low thereafter. In contrast,
serum pregnenolone and 17-hydroxypregnenolone were partially suppressed, and
dehydroepiandrosterone, dehydroepiandrosterone sulfate, and cortisol levels did not
change. Clinically, hyperplastic endometrial histology in three PCO patients reverted to
an inactive pattern, and proliferative endometrium in two other PCO patients became
inactive in one and did not change in the other. Regression of proliferative endometrial
histology occurred in all ovulatory women. Vaginal bleeding occurred in all women studied
during the first month of GnRHa administration, after which all but one PCO patient became
amenorrheic. Hot flashes were noted by all ovulatory women and by four of eight PCO
patients. All PCO patients noted subjective reduction of skin oiliness, and five had
decreased hair growth. We conclude that in premenopausal women: 1) chronic GnRHa
administration results in apparently complete persistent suppression of ovarian steroid
secretion; 2) adrenal steroid secretion is not influenced directly or indirectly; and 3)
its use may be helpful in the treatment of endometrial hyperplasia and ovarian androgen
excess in women with PCO.
