Complete Semen Analysis

What Is a Complete Semen Analysis?

A semen analysis, as defined by the World Health Organization (WHO), is a laboratory test that assesses the characteristics of a man's semen and sperm to evaluate male fertility and identify potential causes of infertility.

This test is often one of the first steps in evaluating male fertility, as it provides insight into both the quantity and quality of sperm. Because male factor infertility can contribute to conception challenges, a semen analysis can help identify potential issues early and guide appropriate next steps.

This test uses both macroscopic and microscopic examination to provide a comprehensive overview of sperm health and function.

  • Macroscopic observation identifies volume, viscosity, and pH
  • Microscopic analysis identifies sperm concentration, motility, progression, and morphology

Together, these measurements help determine whether sperm parameters fall within the normal range for conception.

What Are the Reasons to Schedule a Complete Semen Analysis?

A complete semen analysis may be recommended in several situations, including:

  • Infertility evaluation
  • Post-vasectomy sperm check
  • Reassurance
  • Determining whether to continue cryopreservation

This test can be an important first step in understanding male fertility and guiding next steps in care.
