The polycystic ovary. II. Progesterone plasma levels after the use of antiestrogens.
In the present study, the changes observed in the length of the cycle, basal body temperatures, endometrial histology and plasma progesterone in a group of 18 patients with polycystic ovaries, treated with Clomiphene Citrate, is reported. Two distinctive responses were observed depending on the estradiol/testosterone mean concentration found. Regardless of the induction of ovulation, a clear change in the length of the cycle was observed. Progesterone concentration of 2.1-2.9 ng/ml gave a definite rise in BBT, but no endometrial secretory changes were found in parallel with that concentration. Progesterone concentration above 6.1 ng/ml did induce secretory changes in the endometrium.
