Sperm Concentration
- Sample Type
- Standard
- Fasting
- No
- Unit
- million/mL
Sperm Concentration is the number of spermatozoa per unit volume of semen. As a part of the Semen Analysis, it is a fundamental predictor of male fertility potential. It reflects the efficiency of the testes to produce sperm (spermatogenesis) and the patency of the male reproductive tract. Lower concentrations significantly reduce the statistical probability of natural conception.

Why Context Matters
Concentration varies significantly within the same individual based on abstinence duration (ideally 2-7 days), recent illness/fever, heat exposure, or incomplete collection of the first portion of the ejaculate.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
