[The male factor in fertilization in vitro].
Every sperm parameter has an effect on the chances of fertilization. When fertilization has been obtained with a sperm, the cleavage rate is identical regardless of the count, the mobility or the results of the migration test. On the contrary, in case of teratospermia, the cleavage rate of fertilizing sperms is significantly decreased. The rate of pregnancy by transfer is identical with normal sperm and sperm deficiency.
