[Endometrial steroid receptor levels in habitual abortion in advanced pregnancy]

Estrogen and progesterone reception was examined in the endometrial cytoplasmic and nuclear fraction from apparently healthy subjects and patients with habitual late incompetent pregnancy in the early proliferative and late secretory periods of a menstrual cycle. The reception of the two reproductive hormones in the nuclei and the binding of estrogens in the endometrial cytosol were demonstrated to be significantly higher in the female patients than in healthy subjects. The cytosol estrogen to progesterone reception ratio was increased in the patients in the secretory phase of a menstrual cycle than in normal females. There was a complete normalization of endometrial reproductive hormone receptor levels in the patients undergoing hyperbaric oxygenation.
