Sperm recuperation and cervical insemination in retrograde ejaculation.

Seven infertile patients with retrograde ejaculation, in which spermatozoa could be recuperated from the postejaculation urine, were admitted to a sperm recuperation and cervical insemination program. A noninvasive method for sperm recuperation based on urine alcalinization and serial controls to time masturbation has been used. Insemination has been timed according to BBT charts and cervical mucus characteristics. Pregnancy has been obtained in the seven couples after one to eight treatment cycles.
