Area of Science:

  • Reproductive biology
  • Andrology
  • Semen analysis

Background:

  • Semen quality assessment is crucial for diagnosing male infertility.
  • Traditional microscopic evaluation of sperm motility can be subjective.
  • Novel objective methods are needed to enhance semen analysis accuracy.

Purpose of the Study:

  • To evaluate the correlation between the sperm motility index (SMI) and routine semen analysis parameters.
  • To assess the reliability of SMI as a measure of semen quality.

Main Methods:

  • SMI was measured using an electro-optical device (Sperm Quality Analyzer).
  • Nine hundred sixty-eight semen samples from 812 patients were analyzed prospectively.
  • Samples were simultaneously evaluated by microscopic analysis and SMI.

Main Results:

  • SMI showed statistically significant correlations with motile cell concentration, total cell concentration, and percent motile cells.
  • SMI results reliably represented semen quality assessments performed by experienced andrologists.
  • The electro-optical device provided objective semen quality data.

Conclusions:

  • The sperm motility index offers a reliable and objective reflection of semen motility parameters.
  • SMI is a valuable tool for assessing semen quality in clinical settings.
  • This novel parameter enhances the objectivity of semen analysis.
