Summary
Immunoglobulin A (IgA) levels in seminal plasma correlate with male fertility. IgA decreases in azoospermia and increases with oligozoospermia, suggesting autoimmune involvement in male infertility.
Area of Science:
- Reproductive Immunology
- Urology
Context:
- Seminal plasma analysis is crucial for male infertility investigations.
- Immunoglobulins play a role in reproductive health and immune responses within the male reproductive tract.
Purpose:
- To quantify immunoglobulin (IgA, IgG, IgM) levels in seminal plasma of men from infertile couples.
- To investigate the relationship between immunoglobulin levels and semen quality parameters (azoospermia, oligozoospermia, morphology).
Summary:
- Immunoglobulins IgA and IgG were detected in all seminal plasma samples from 168 men.
- IgM was present in 36.3% of samples.
- IgG levels remained constant across different semen qualities, while IgA levels varied significantly, decreasing in azoospermia and increasing in oligozoospermia and cases with poor morphology.
Impact:
- Findings suggest that IgA levels in seminal plasma may serve as a biomarker for certain male infertility conditions.
- The observed IgA variations point towards potential autoimmune reactions affecting the testes, epididymis, or accessory glands as a cause of infertility.
