[Laparoscopy in the differential diagnosis of the causes of female infertility. II. 17-beta estradiol and progesterone levels in the peritoneal fluid and blood serum].

In 104 infertile women the presence of the ovulation stigma detected during the laparoscopy was compared with the behaviour of the concentration of 17-beta estradiol and progesterone in the peritoneal fluid and in the blood. It was shown that the simultaneous and performed twice during one cycle measuring of the level of these hormones in peritoneal fluid and in blood is of a great value in the diagnosis of ovulation in infertile women--and is correlated with the presence of stigma. It was also shown that the lack of stigma and the lower values of concentrations of steroid hormones in peritoneal fluid and blood suggest the lack of ovulation in spite of the presence of corpus luteum.
