Men with high ejaculate volume may have

Area of Science:

  • Andrology
  • Reproductive Endocrinology
  • Urology

Background:

  • High ejaculate volume is often associated with lower sperm concentration.
  • Assessing male fertility requires comprehensive analysis of ejaculate parameters.

Purpose of the Study:

  • To compare andrological and endocrinological data between patients with high ejaculate volume and a control group.
  • To investigate the implications of high ejaculate volume on sperm output and fertility prognosis.

Main Methods:

  • Clinical, andrological, and endocrinological data collection from 101 patients with ejaculate volume >= 8.0 ml.
  • Comparison of data with 100 consecutive infertility clinic patients.
  • Correlation analysis of various parameters within and between groups.

Main Results:

  • A significant difference in total sperm output was observed between the high ejaculate volume group and the control group.
  • The high ejaculate volume group exhibited characteristics suggestive of 'dilution oligozoospermia'.
  • Correlations between different clinical and andrological parameters were identified within both groups.

Conclusions:

  • Total sperm output, not just sperm density, is crucial for accurate male fertility assessment in high ejaculate volume cases.
  • The term 'relative oligozoospermia' is proposed for cases with very high ejaculate volumes to avoid misinterpretation.
  • Considering total sperm output can prevent a falsely unfavorable fertility prognosis in men with high ejaculate volumes.
