Summary
Sperm motility parameters were analyzed using computer-assisted semen analysis. Higher percentages of motile spermatozoa were observed during the spring-summer season compared to autumn-winter.
Area of Science:
- Reproductive biology
- Andrology
- Spermatozoa analysis
Background:
- Seasonal variations can influence male reproductive parameters.
- Understanding these variations is crucial for reproductive health assessments.
Purpose of the Study:
- To investigate seasonal changes in sperm movement parameters.
- To compare sperm motility between autumn-winter and spring-summer periods.
Main Methods:
- Computer-assisted semen analysis (CASA) was utilized.
- Analysis of 473 sperm specimens from 12 healthy sperm donors.
- Comparison of motility parameters across different seasons.
Main Results:
- A statistically significant increase in the percentage of motile spermatozoa was found during spring-summer.
- Sperm movement parameters exhibited seasonal fluctuations.
Conclusions:
- Sperm motility shows a seasonal pattern, being higher in spring-summer.
- Seasonal variations should be considered in the interpretation of semen analysis results.
