Circulating sperm antibodies: indications for testing in infertile couples.

Area of Science:

• Reproductive Immunology
• Infertility Diagnostics

Background:

• Immunologic factors, specifically sperm antibodies, can contribute to infertility.
• Evaluating sperm antibodies is important in diagnosing infertility, but their role in relation to post-coital test (PCT) quality and semen analysis needs further clarification.

Purpose of the Study:

• To investigate the relationship between sperm antibody titers and the quality of post-coital tests and semen analysis in infertile couples.
• To determine the significance of sperm antibody testing in infertile men with both normal and abnormal semen parameters.

Main Methods:

• Serum sperm antibody titers were assessed in 73 infertile couples using the F-D and Kibrick agglutination tests.
• Couples were categorized based on post-coital test quality (poor or normal) and male semen analysis results (abnormal or normal).

Main Results:

• Sperm antibodies were detected in 10.5% of men and 18.4% of women with poor PCTs, and 6.6% of men and 20.0% of women with normal PCTs.
• No significant difference in sperm antibody incidence was observed between men with abnormal semen analysis and those with normal semen analysis.
• The incidence of sperm antibodies was notable in both poor and normal PCT groups, suggesting broader applicability of testing.

Conclusions:

• Sperm antibody testing is indicated for infertile couples, particularly those with poor post-coital tests.
• Testing for sperm antibodies in infertile men is significant regardless of semen analysis results, aiding in the identification of candidates for immunologic treatment.
