Evaluation of sperm fertilizing ability using the Sperm Quality Analyzer

Area of Science:

• Reproductive Biology
• Andrology
• In Vitro Fertilization

Background:

• Assessing human sperm fertilizing potential is crucial for reproductive medicine.
• Quantitative estimation of sperm motility aids in evaluating male fertility.
• Standard in vitro fertilization (IVF-ET) success rates depend on sperm quality.

Purpose of the Study:

• To evaluate the fertilizing ability of human spermatozoa using the Sperm Quality Analyzer.
• To analyze correlations between the sperm motility index, sperm penetration index (SPA), and IVF-ET fertilization rates.
• To determine the reliability of the Sperm Quality Analyzer in predicting IVF-ET outcomes.

Main Methods:

• Retrospective analysis of 104 fresh semen samples from 81 men undergoing IVF-ET.
• Correlation analysis between sperm motility index, sperm concentration, motility, motile sperm concentration, and sperm penetration index (SPA).
• Categorization of sperm motility index into 'poor', 'medium', and 'good' for evaluating IVF-ET fertilization rates.

Main Results:

• The sperm motility index showed significant correlations with sperm concentration, motility, and motile sperm concentration (p < 0.001).
• A significant correlation was found between the sperm motility index and the sperm penetration index (p < 0.001).
• Higher IVF-ET fertilization rates were observed with 'good' sperm motility index categories (76.0%) compared to 'medium' (44.2%) and 'poor' (34.7%) categories (p < 0.001).

Conclusions:

• The Sperm Quality Analyzer provides a reliable quantitative estimation of sperm motility.
• The sperm motility index is a significant predictor of sperm fertilizing ability and IVF-ET success.
• This inexpensive device aids in assessing male fertility potential for assisted reproductive technologies.
