Testicular microlithiasis is not a risk factor for the production of antisperm antibody in infertile males

Abstract:
Testicular microlithiasis (TM) is a pathological event characterised by the presence of microliths within the testicular entities, and such calcium deposition is thought to have deleterious impacts on the structure of blood-testis barrier (BTB). Breaches in the BTB appear to be a risk factor for antisperm antibody (ASA) production, which is reported to have negative influence on human fertility. Thus, the theories are provocative that ASA formation is elicited in TM men, and the resultant ASA will accordingly affect the fecundity in these men. To illustrate these hypotheses, this study enrolled 22 infertile men incidentally diagnosed with TM by testicular ultrasound evaluation. Sperm samples were collected, and direct immunobead test was used to determine the ASA levels. None of the infertile men with TM were found to display significant levels of ASA, whilst relatively abnormal sperm parameters in these cases were revealed by semen analysis. These observations suggest that TM exposure does not increase the risk of ASA production in infertile men, and therefore, ASA is discarded as an active participant in the development of infertility in TM men. Nevertheless, disrupted spermatogenesis resulting from TM may, at least in part, have certain implications for the pathogenesis of TM-associated infertility.
Insights
Testicular microlithiasis (TM) does not increase antisperm antibody (ASA) production in infertile men. However, disrupted spermatogenesis in TM may contribute to infertility.
Area of Science:
- Reproductive Medicine
- Urology
- Andrology
Background:
- Testicular microlithiasis (TM) involves calcium deposits in testes, potentially impacting the blood-testis barrier (BTB).
- Breaches in the BTB are linked to antisperm antibody (ASA) production, which can impair male fertility.
Purpose of the Study:
- To investigate the relationship between TM and ASA production in infertile men.
- To determine if ASA plays a role in TM-associated infertility.
Main Methods:
- Enrolled 22 infertile men with incidentally diagnosed TM via testicular ultrasound.
- Collected sperm samples for ASA level determination using direct immunobead test.
- Performed semen analysis to assess sperm parameters.
Main Results:
- No significant ASA levels were detected in infertile men with TM.
- Abnormal sperm parameters were observed in the TM group.
- TM exposure did not correlate with increased ASA risk.
Conclusions:
- ASA is unlikely to be a primary factor in TM-associated infertility.
- Disrupted spermatogenesis, potentially caused by TM, may contribute to infertility in these patients.
