A comparison of the bovine cervical mucus penetration test and the postcoital test.

In 68 ejaculates an in vitro bovine cervical mucus penetration-test (Penetrak) was compared to the postcoital-test and the spermiogram. There was a positive correlation between the Penetrak-Test and concentration, motility, and morphology of the spermatozoa, however there was no correlation to the postcoital test. In connection with the PCT, the bovine mucus penetration-test seems to be a useful tool in the exploration of male infertility.
