Summary
The presence of antisperm antibodies did not significantly impact overall semen quality or sperm function in most cases. Sperm motion analysis is unlikely to be effective for screening immunological male infertility factors.
Area of Science:
- Reproductive Immunology
- Andrology
- Sperm Function Analysis
Background:
- Antisperm antibodies (ASAs) can potentially impair male fertility by affecting sperm function.
- Understanding the incidence and impact of ASAs on sperm parameters is crucial for diagnosing male infertility.
Purpose of the Study:
- To determine the incidence of antisperm antibodies in normozoospermic and abnormal semen samples.
- To evaluate the impact of antisperm antibodies on sperm motility and movement parameters.
Main Methods:
- Semen samples from 144 patients were classified using WHO guidelines and Kruger's strict criteria.
- Sperm motility was assessed using computer-assisted semen analysis (CASA) with a Makler chamber.
- Antisperm antibodies were detected using the Mar Test and Immunobead assays to identify immunoglobulin type and location.
Main Results:
- No significant association was found between the presence of antisperm antibodies and overall semen quality.
- Antibody incidence was 15% in normozoospermic samples and 9.5% in abnormal samples.
- While sperm linearity was reduced in abnormal samples with antibodies, the immune response did not significantly affect the sperm pathway in most instances.
Conclusions:
- The presence of antisperm antibodies does not appear to significantly impair sperm function or semen quality in the majority of cases studied.
- Sperm motion analysis alone may not be a reliable screening tool for identifying immunological factors contributing to male infertility.
