Circulating sperm antibodies: indications for testing in infertile couples.
Sperm antibody titers were evaluated in the serum of 73 infertile couples by the F-D and Kibrick agglutination tests, to study the relationship of the quality of post-coital tests and semen analysis. Thirty-eight couples had poor post-coital tests, fifteen couples had normal post-coital tests, and twenty couples revealed abnormal semen pictures of the males. In the first two groups, semen analysis was normal. The incidence of sperm antibodies was 10.5%, 6.6% in men, and 18.4%, 20.0% in women, with poor and normal post-coital tests, respectively. This suggests that sperm antibody testing is equally indicated in infertile couples with poor post-coital tests. In addition, there was no difference in the incidence of sperm antibodies in men with poor semen pictures and those with normal semen analysis in this infertile population. This suggests the significance of sperm antibody testing in infertile men with abnormal and normal semen pictures after correcting other infertility factors, in order to detect those patients who could benefit from treatment of such immunologic problems.
