Andrological parameters in men with high sperm counts and possible correlation with age

Area of Science:

• Andrology
• Reproductive Medicine
• Sperm Biology

Background:

• Semen parameters are crucial for male fertility assessment.
• The relationship between semen volume and sperm quality requires further investigation.

Purpose of the Study:

• To evaluate the impact of semen volume on sperm parameters in men with high sperm counts.
• To determine optimal semen volume ranges for sperm motility, viability, and morphology.

Main Methods:

• Analysis of 286 human semen samples categorized by volume: low (<1 ml), normal (1-5 ml), and high (≥6 ml).
• Assessment of routine andrological parameters including sperm count, motility, viability, and morphology.
• Correlation analysis between sperm count, semen volume, and patient age.
• Measurement of seminal fructose content.

Main Results:

• Sperm motility and viability were lowest in low-volume samples and highest in normal-volume samples.
• Low-volume semen showed significantly decreased mean fructose content compared to normal-volume semen.
• Patients with low-volume semen and high sperm counts were older than those with normal volume and high sperm counts.
• Morphological normality showed a similar trend but lacked statistical significance.

Conclusions:

• Semen volume is a critical factor influencing sperm quality, with normal volumes (1-5 ml) associated with superior motility, viability, and fructose levels.
• Low semen volume (<1 ml) may indicate reduced sperm quality and is associated with older patient age in men with high sperm counts.
• Semen samples with volumes between 1-5 ml should be considered normal regarding motility, viability, and morphology, even with high sperm counts.
