Serum estrone, estradiol and estriol concentrations during oral hormone therapy after oophorectomy.
Serum estrone, estradiol and estriol concentrations during estradiolvalerate-norgestrel therapy for women who have undergone oophorectomy were studied. The patients in one group received 1 mg of estradiolvalerate in the morning and 2 mg of estriolsuccinate in the evening. The estrone and estradiol concentrations of the first and fifth day were at roughly the same level and the treatment caused no estrogen cumulation. The estriol concentrations on the fifth day were distinctly higher than on the first, owing to the conversion of estrone and estradiol into estriol. The other group of women were placed on a regimen of 2 mg of estradiolvalerate plus 0.5 mg of norgestrel in the morning and 2 mg of estriolsuccinate in the evening. Here again, the estrone and estradiol concentrations on the first and fifth days were similar.
