Abstract: | One hundred and sixty-two females who attended our infertility clinic were selected according to the quality of their cervical mucus. Only mucus of extremely high quality was used in the study to determine the influence of different semen parameters on the postcoital test results. All mucus samples were evaluated 8 h following coitus. The results of the postcoital tests were divided into group I (less than 7 spermatozoa per 400 X magnification) and group II (greater than 7 spermatozoa per 400 X magnification). The results of the statistical analysis indicated the order of importance of the different semen parameters during postcoital testing. By using the stepwise discriminant analyses, it was calculated that the sperm concentration and forward progression rate of the spermatozoa are discriminating factors between the two groups. |
