title: Relationship between fertility, semen analysis and human sperm penetration of zona-free hamster eggs.
abstract: Spermatozoa from 12 fertile donors, 37 infertile patients with normal spermiogram and 61 infertile men with abnormal semen analysis were assessed with zona-free hamster eggs penetration test, according to Barros. We obtained significant differences in positive penetrations in the 3 groups tested: 96 per cent of positive results for the first group, 59 per cent for the second and 21 per cent for the third group. A significant relationship between penetration results and sperm count, motility and morphology is evidenced.
