title: [Teratospermia and migration of spermatozoa in vitro and in vivo].
abstract: The comparative study of morphological anomalies of spermatozoon before and after penetration shows that in vivo or in vitro migration causes a selection of the spermatozoon. This selection is not complete. Anomalies of the midpiece or of the flagella inhibe the spermatozoon progression but morphological anomalies of the head are not a handicap for the migration. this observation seems to indicate that spermatozoa with chromosomic failures can paticipate to the fertilization.
