Artificial insemination by donor results in relation to husband's semen

A retrospective analysis was undertaken to determine whether there was any difference in conception and abortion rate in an artificial insemination by donor program between couples whose husbands were azoospermic (group A) and couples whose husbands were severely subfertile (group O). The pregnancy rate was significantly higher in group A (64%) than in group O (47%) (p less than 0.05). The abortion rate was significantly lower in group A (10%) than in group O (23%) (p less than 0.05). This study confirms the opinion of other authors [4, 9] that pregnancy may occur despite severely abnormal semen. In fact, the difference in pregnancy and abortion rate between the two groups could be explained by assuming that the average fertility of the women in group O is lower than that in group A.
