Accuracy of sperm velocity assessment using the Sperm Quality Analyzer V

Area of Science:

• Reproductive Medicine
• Andrology
• Biomedical Engineering

Background:

• Accurate assessment of human sperm functional capacity is crucial for diagnosing male infertility.
• Traditional methods for sperm analysis can be time-consuming and costly.
• The Sperm Quality Analyzer with visualization system (SQA V) was developed for rapid, low-cost quantitative sperm evaluation.

Purpose of the Study:

• To evaluate the correlation between new parameters from the SQA V and established computer-aided sperm analysis (CASA) estimates.
• To determine if SQA V can provide reliable sperm quality and velocity assessments.

Main Methods:

• Semen quality analysis was performed on 66 fresh human sperm samples.
• Samples were analyzed using both the SQA V system and CASA.

Main Results:

• SQA V demonstrated significant correlations with CASA for total sperm concentration, sperm motility, and progressive motile sperm percentage.
• SQA V's sperm velocity assessment correlated significantly with CASA measures of motility, progressive motility, straight-line velocity, curvilinear velocity, and average path velocity.
• No significant correlation was found between SQA V velocity and CASA's amplitude of lateral head displacement, beat cross frequency, straightness, or linearity.

Conclusions:

• Sperm motility assessment is a key factor in predicting human sperm functional capacity.
• The SQA V system is considered a valuable tool for screening sperm quality in male infertility management.
• SQA V offers a rapid and cost-effective alternative for evaluating sperm parameters relevant to fertility.
