The percentage of Y spermatozoa was determined in sperm specimens from 73 donors with known spermiogram; mean value was 46%. No difference between donors with high or low sperm counts was observed. The penetration capacity of the sperm in cervical mucus was investigated in 59 cases using an in vitro test. The cervical mucus content of Y spermatozoa was significantly higher (54.2-56.7%) than that of the sperm specimens. It thus appears that cervical mucus may be somewhat selective of Y spermatozoa.
