Success of donor insemination and male diagnosis.

Of 72 women receiving artificial donor insemination with frozen semen, 49 (68%) conceived. The success rate was significantly better in patients whose husbands were azoospermic (79.5%) than in women whose mates were oligospermic (54.5%). This result may be explained on the assumption that the most fertile women in the latter (male oligospermic) group have disappeared through previous natural conception. It may be concluded that the diagnosis of male infertility is a factor influencing the probability of conception following artificial insemination with donor semen.
