[In vitro effects of preovulatory human follicular liquid on migration of human spermatozoa].

Abstract

In vitro measurements of spermatozoa migration in different media showed a 75% increase in the number of spermatozoa migrating into preovulatory human follicular fluid versus Menezo's fluid. However after 4 h storage in either medium, total and progressive motility of the spermatozoa was lower in follicular fluid than in Menezo's fluid. A positive correlation was evident between the spermatozoa migration in follicular fluid and the concentration or motility of spermatozoa in fresh sperm.
