Simultaneous determination of human sperm morphology and viability: simple office technique

Area of Science:

• Reproductive Biology
• Andrology
• Semen Analysis

Background:

• Semen quality assessment is crucial for evaluating male reproductive health.
• Sperm morphology and viability are key indicators of semen quality.
• Accurate staining techniques are essential for reliable semen analysis.

Purpose of the Study:

• To compare the effectiveness of eosin-nigrosin and hematoxylin-eosin staining methods.
• To evaluate their utility in characterizing spermatozoa for semen quality assessment.
• To determine if eosin-nigrosin provides additional diagnostic information.

Main Methods:

• Comparative analysis of eosin-nigrosin and hematoxylin-eosin staining techniques.
• Assessment of sperm morphology and viability using both methods.
• Statistical comparison of results obtained from the two staining protocols.

Main Results:

• Both eosin-nigrosin and hematoxylin-eosin demonstrated comparable efficacy in differentiating spermatozoa.
• Eosin-nigrosin staining allowed for the determination of viable cells within each morphological category.
• The eosin-nigrosin technique proved to be a simple and rapid method.

Conclusions:

• Eosin-nigrosin and hematoxylin-eosin yield comparable results for sperm characterization.
• Eosin-nigrosin offers the advantage of assessing sperm viability alongside morphology.
• This technique can provide valuable supplementary data for male infertility diagnosis.
