Infertility in men and women with spermagglutinins is the result of disturbed penetration and migration of spermatozoa in the cervical mucus. In ejaculates with partial spermagglutination caused by autoimmunization, the progressive propulsion of the sperm was changed into stationary, shaking movement the moment the sperm came into contact with cervical mucus. The same alteration in spermatozoal motility pattern also occurred when spermatozoa from a normal, fertile ejaculate came into contact with cervical mucus of a woman whose serum contained sperm antibodies. This shaking phenomenon was visualized in a simple test, the sperm cervical mucus contact test. The authors demonstrated that sensitized spermatozoa exhibit the shaking phenomenon after contact with the glycoprotein fraction of the cervical mucus and not after contact with the aqueous fraction. Therefore, the hypothesis is introduced that the shaking phenomenon is due to an interaction between sensitized spermatozoa and the glycoprotein micelles in cervical mucus.
