Summary. Incubation of human spermatozoa in capacitation media for 24 h results in a significant increase in acrosome reacted spermatozoa as compared to preincubation (baseline) levels. By contrast, sperm samples recovered from the cervix for as long as 72 h after coitus only showed baseline percentage of acrosome reacted spermatozoa. These results indicate that spermatozoa do not undergo the acrosome reaction during cervical storage and suggest that cervical mucus suppresses the spontaneous acrosome reaction of spermatozoa that become capacitated in the cervix.
