[Structural anomalies in disorders human of sperm motility in 60 cases of asthenospermia].

The morphological study of sperm cells was carried out in sixty cases of proven asthenospermia. In fifteen of the cases, structural abnormalities, related to impaired cell mobility, have been shown, namely when spermatozoa, which were immobile in a large majority, presented short tails or characteristic ultrastructural abnormalities of the axonemal complex.
