Therapeutic insemination.

Abstract

Except in special circumstances, therapeutic insemination with a husband's sample has a low success rate. Couples in whom oligozoospermia has been identified as the principal cause of infertility do not benefit from therapeutic insemination by husband. Because of this low success rate, intrauterine insemination to provide sperm in closer proximity to the egg has become popular, but intrauterine insemination also has a low success rate. We suggest that intrauterine insemination should be approached aggressively in cases of male factor infertility. The recipient should be stimulated to enhance egg production and closely monitored for ovulation. A semen specimen of not less than 1 X 10(6) motile sperm with antibiotics added should be placed in the uterus the day after ovulation. If no pregnancies occur within four cycles, alternate approaches should be considered. Therapeutic insemination by donor involves careful donor selection to avoid inheritance of malformations and familial diseases. Because of the possibilities of sexually transmitted diseases, careful and repeated screening should be conducted. A complete sexual history should be obtained, and donors should be excluded if they have had any homosexual contact since 1978, if they have been an intravenous drug user, if they come from a geographic area where the sex ratio of AIDS is close to 1:1, or if they have recently had multiple sexual partners. A permanent record preserving the confidentiality but allowing the tracing of genetic anomalies, even if not present at birth, should be kept.
