Frequency of Y-chromatin bearing spermatozoa in intracervical and intrauterine postcoital tests

By means of the intracervical Sims-Huhner-test and supplementary to this, the intrauterine postcoital test, the percentages of Y-chromatin-positive spermatozoa was determined after penetration into the cervix and the cavum uteri. A significant rise of the Y-positive sperms after penetration could be observed. There was no influence of certain parameters of the spermiogram upon the relationship of X- to Y-sperms after the PCT. Statistical calculations show the dependences of the positive and negative postcoital tests upon the individual parameters of the cervical factors and the spermiogram.
