Abstract

Estrous bovine cervical mucus (BCM) was evaluated as a practical substitute for midcycle human cervical mucus (HCM) in the sperm-cervical mucus penetration technique (S-CMPT). Analysis of semen samples from 299 men of infertile couples suggested that up to 95% of the S-CMPT analyses with BCM were compatible with results expected with HCM. Results from a secondary S-CMPT with BCM using donor sperm treated with seminal plasma or cervical mucus extracts from partners of infertile couples indicated 70 and 88% agreement with the clinical S-CMPT obtained with the semen and cervical mucus samples, respectively. Seminal plasma samples from men with serum antisperm antibodies decreased the ability of donor sperm to penetrate BCM in the Secondary S-CMPT. Our results indicate that estrous BCM possess those basic qualities of HCM that support human sperm motility, allow for normal sperm penetration, and interact with antibody-treated sperm to inhibit penetration and to produce the sperm shaking phenomenon.

Antibodies: Agglutination

Antibody-mediated agglutination is the clumping of cells in the presence of antibody, which binds multiple cells together. This enhances the clearance of pathogens. Find the latest research on antibody-mediated agglutination here.
