Retrograde ejaculation, semen flows into the bladder because of failure of the bladder neck to close, is an uncommon cause of male infertility. Many pregnancies have been tried by artificial intrauterine insemination of the wife with the husband's sperm recovered from voided urine. Major problems in the use of retrograde djaculation specimens for artificial insemination are (1) the acidity of the urine, (2) the osmotic pressure of the urine, (3) the dilution effect caused by the urine and (4) urine contamination of the cell suspension. We report a case of successful pregnancy using Ham's F-10 medium, which contained 10% cord serum in the retrograde ejaculation patient.
