Ethinyl estradiol administration and plasma steroid concentrations in ovariectomized women.

Abstract

The effect of ethinyl estradiol treatment on the plasma levels of cortisol, corticosterone, deoxycorticosterone, progesterone, testosterone, dehydroepiandrosterone sulfate, delta4-androstenedione, and estrone was studied in eight women. All the subjects had undergone ovariectomy and hysterectomy at least one year prior to this study. The systemic concentration of cortisol and the binding of cortisol were significantly increased, paralleling the increased transcortin concentration due to ethinyl estradiol treatment. Corticosterone concentration was also significantly increased after three days of estrogen administration and this level continued to be higher than normal as long as patients were treated with estrogens, but there was no change in the plasma concentration of deoxycorticosterone. The plasma levels of progesterone testosterone, dehydroepiandrosterone sulfate, delat4-androstenedione and estrone or the ratio of estrone to delta4-androstenedione did not change with ethinyl estradiol treatment. These observations suggest that the administered estrogen increased the transcortin concentration and had only a limited effect on adrenocortical steroidogenesis.
