Comparison of Results of Aid with Fresh and Frozen Semen

The use of frozen semen for AID has gained wide acceptance and a relatively large number of pregnancies have been reported following the use of this technique.1 A number of reports dealing with either fresh or frozen semen use in AID have been published.2-6 some authors have attempted to compare the published results for the two types of semen and concluded that the pregnancy rates are either similar or slightly lower when frozen semen is employed. 3,6,7 Actually, the reported data are difficult to evaluate. One has to compare results obtained by different groups of investigators practicing in various parts of the world, treating different populations of infertile couples and utilizing different technical and therapeutic approaches. Such comparisons are at best difficult. However, in several reports the same groups of investigators compared results with each type of semen and also concluded that pregnancy rates are indeed similar or only slightly decreased when frozen semen is used.8-10 While pregnancy rate is one of the most important parameters used in the evaluation of efficacy of AID, it is not the only measure. The number of cycles of insemination required for pregnancy to occur should also be considered when comparing the effectiveness of AID with fresh and frozen semen.
