Abstract
The relation between presence of antispermatozoal antibodies in infertile men and the inhibition of the in vitro sperm penetration into cervical mucus (CM) was studied with the sperm cervical mucus contact (SCMC) test. The tests were performed with semen from infertile men and from semen donors. The CM used permitted good penetration of normal spermatozoa. The so called “shaking phenomenon”, the result of a specific interaction of spermatozoa and CM, was expressed in the shaking percentage (S%).The S% did not change beyond the experimental error within 30 min after mixing semen and CM. The S% was 30 at the most in 194 out of 198 SCMC tests with normal donor semen and normal pre‐ovulatory CM. Significant negative correlations (P < 0.005) were found between the readings of the sperm penetration meter (SPM) test on one hand and the S%, the sperm agglutination titer in the serum and the sperm agglutination titer in the seminal plasma (SP) on the other hand. Significant positive correlations (P < 0.005) were found between the S% and the sperm agglutination titer in the SP. The sperm agglutination titer in serum and in SP correlated significantly better (P < 0.02) with the S% in the SCMC test than with the readings of the SPM test.It was concluded that: 1. A high S% is highly specific for the presence of antispermatozoal antibodies in infertile men, 2. The SCMC test is more suited than the SPM test for studying the effect of antispermatozoal antibodies on the penetration and migration of spermatozoa into CM,
