Sperm Count Criterion for Normal Semen
A semen analysis is performed to assess male fertility. It evaluates several parameters, including sperm concentration.
WHO Minimum Sperm Concentration
The World Health Organization (WHO) provides guidelines for interpreting semen analysis results. For a semen sample to be considered normal in terms of sperm count, the minimum concentration is a key factor.
Based on the provided information, the WHO criterion for minimum sperm count per milliliter (ml) in normal semen is 40 million.
This value aligns with option D.
Calculation recap:
- Parameter: Minimum Sperm Count per ml
- Guideline: WHO criterion
- Value: 40 million/ml
