[Inadequate corpus luteum function in benign breast-diseases (author's transl)].
The amount of progesterone and estradiol secreted by human corpus luteum depends upon an adequate release of FSH and LH by pituitary gland during follicular phase and ovulation. In this paper, plasma determination of progesterone and estradiol were carried out in 109 women with benign breast disease during the luteal phase of their menstrual cycle. Results obtained were compared with those observed in 25 normal women studied in the same conditions. In women with benign breast disease, the curve of daily progesterone concentrations during luteal phase was lower than that of normal women. The progesterone peak at 5th day of luteal phase was only 8,1 +/- 3.8 ng/ml instead of 17.2 +/- 3.5 ng/ml in normal women. No significative difference was observed concerning plasma estradiol between patients and normal women. These results indicate that women with benign breast disease have an inadequate corpus luteum function which may be the result of disorder of ovulation. Pathophysiological implications resulting from this observation are discussed.
