    Summary

    This study optimized a triple-stain technique for semen analysis, improving spermatozoal morphology and viability assessments. The adapted method enhances visibility and reduces background noise for more accurate results in routine analysis.

    Area of Science:

    • Reproductive Biology
    • Cell Biology
    • Analytical Chemistry

    Background:

    • Semen analysis is crucial for assessing male fertility.
    • Accurate evaluation of spermatozoal morphology and viability is essential.
    • Existing staining techniques may have limitations in routine analysis.

    Purpose of the Study:

    • To adapt the Talbot and Chacon triple-stain technique for routine semen analysis.
    • To evaluate spermatozoal morphology, viability, and acrosome integrity.
    • To optimize the staining protocol for improved results.

    Main Methods:

    • Adaptation of the triple-stain technique for semen analysis.
    • Evaluation of spermatozoal morphology, viability (live/dead), and acrosome status.
    • Optimization of fixation and dilution steps, avoiding pre-fixation centrifugation.

    Main Results:

    • The modified triple-stain technique provides excellent visibility of spermatozoal structures with low background.
    • Optimal results were achieved by avoiding pre-fixation centrifugation, diluting semen before fixation, and fixing in suspension.
    • Trypan Blue underestimated dead spermatozoa; other supravital stains were less satisfactory. Round cells were not evaluated.

    Conclusions:

    • The adapted triple-stain technique is suitable for routine semen analysis.
    • This method allows for comprehensive evaluation of spermatozoal characteristics.
    • Further investigation into supravital stains and round cell evaluation may be warranted.
