Artificial insemination with donor semen: the necessity of frequent donor screening.

Artificial insemination with donor semen has become a well established alternative for couples with untreatable male factor infertility. Because of the widespread use of donor insemination, and the increasing awareness and prevalence of sexually transmitted diseases, the American Fertility Society recently redrafted procedural guidelines for the use of donor screening for insemination. Our series of donor screenings is reported to emphasize the necessity of donor evaluations at frequent intervals. From June 1986 through August 1987, 48 healthy male volunteers presented as potential semen donors for our donor program. Each was evaluated with a careful medical history, physical examination and 2 semen analyses for evidence of sexually transmitted disease. On initial evaluation, no donor presented with a positive human immunodeficiency virus antibody, abnormal karyotype, elevated serum glutamic oxaloacetic transaminase, rapid plasma reagent, or positive cultures for Chlamydia or Mycoplasma. One potential donor was excluded because of a positive hepatitis B-core antibody and 1 because of a positive IgM test for cytomegalovirus. At initial examination 3 potential donors had a positive culture for Ureaplasma; all 3 were treated with 3 weeks of tetracycline, and repeat cultures were all negative. Routine followup screening was performed on all donors at 3-month intervals for all sexually transmitted diseases. During this 14-month period cultures converted to positive for Ureaplasma in 4 donors. Furthermore, 1 donor at 6 months contracted gonorrhea. He was treated but no longer used as a donor. Since initiation of the outlined protocol more than 800 inseminations have been performed using fresh semen with no case of sexually transmitted diseases reported from our recipients. We conclude that careful sexual history, and frequent donor and semen evaluation are necessary for prevention of diseases that might be transmitted sexually. If these precautions are strictly observed use of donor semen is safe and effective.
