The effect of lectins on human spermatozoa in the capillary sperm penetration test

: The effect of the commercial lectin (Con A, PHA, SRA, WGA and UEA) as well as of the prepared by us extract from roots of Arum maculatum (Am and AM 80 degrees C) was studied on migration of human spermatozoa in bovine estrous cervical mucus, using the capillary sperm penetration test of Kremmer. It was established that Con A, PHA and AM inhibited the migration of spermatozoa in a concentration, in which they agglutinated human spermatozoa in vitro. Nonagglutinating human spermatozoa SBA and AM 80 degrees C inhibited also the migration of spermatozoa in the mucus.
