[Male infertility and intrauterine insemination with abnormal sperm].

Intra-uterine insemination of capacitated sperm has disappointing results when this sperm is abnormal, since the overall pregnancy rate does not exceed 11 p. cent of the couples who have not given up before the 6th cycle of treatment. However, considering the ineffectiveness of the treatments of idiopathic or secondary oligo-astheno-teratospermia, and the still limited effectiveness of fertilization in vitro with his type of sperm, intra-uterine CAI may currently be offered for a limited time to sterile couples with very abnormal sperm, contingent on a precise methodology in the preparation of the sperm as well as the time of ovulation.
