Semen parameters in 114 fertile men
Summary
Semen quality, including sperm motility and count, significantly correlates with normal sperm morphology. Sperm motility and motility index decrease over time, while sperm velocity generally increases post-ejaculation.
Area of Science:
- Reproductive Medicine
- Andrology
- Spermatozoa Analysis
Background:
- Semen quality is crucial for male fertility.
- Understanding temporal changes in semen parameters post-ejaculation is important for accurate assessment.
Purpose of the Study:
- To evaluate semen quality parameters in fertile men.
- To investigate the time-dependent changes in sperm motility, velocity, and morphology.
- To determine correlations between different semen quality indicators.
Main Methods:
- Analysis of semen samples from 114 fertile men.
- Assessment of sperm count, motility, velocity, motility index, and normal morphology.
- Evaluation of parameter changes over time post-ejaculation.
Main Results:
- Sperm motility and motility index decreased by 5-10% per hour.
- Sperm velocity generally increased in the first 4 hours post-ejaculation.
- Moderate correlations found between sperm count, motility, and normal forms.
Conclusions:
- Semen quality parameters exhibit dynamic changes post-ejaculation.
- Sperm count, motility, and normal morphology are moderately correlated.
- Temporal analysis provides insights into sperm viability and function.
