[Clinical, hormonal and celioscopic examination of the corpus luteum in sterility without pelvic lesions].

58 sterile women who had perfect biphasic temperature curves through their menstrual cycles were examined by laparoscopy in the luteal phase of the cycle. No pelvic lesion was found. In 21 patients it was seen that the follicle had not ruptured (the so-called non-ruptured follicle syndrome). In a further 9 cases there was no luteal follicle to be seen on the surface of the ovary. The respective values of the plasma biochemical parameters which reflect ovarian secretion in the luteal phase are discussed; the importance of oestrogen secretion at the 6th day of the luteal phase is emphasized. It has been shown that there are significant statistical differences in the levels of oestradiol in the blood.
