[Treatment of infertility, caused by retrograde ejaculation, using intrauterine insemination with sperm enhanced by the "swim up" method].

The causes and the pathomechanism of retrograde ejaculation are reported by the authors. In their case following the failure of the conservative treatment a successful intrauterine insemination was carried out in the superovulatory monitored cycle by semen are covered from the postcoital urine and washed in Ham-F-10. After an undisturbed twin pregnancy a mature male and a female infant was born using Caesarean section. There is a greater chance for pregnancy if the sperms recovered from the postcoital urine are numerous and if their motility is good.
