Understanding Sperm Analysis
What is Sperm Analysis?
Sperm analysis (semen analysis) is a laboratory test that evaluates the health and fertility potential of male reproductive cells. It measures various parameters including sperm count, movement, shape, and overall semen quality to assess male fertility.
Key Parameters
- •Volume: Amount of semen produced
- •Concentration: Number of sperm per milliliter
- •Motility: Percentage of moving sperm
- •Morphology: Percentage of normally shaped sperm
- •Vitality: Percentage of live sperm
Functional Sperm Calculation
Functional Sperm = Volume × Concentration ×
Motility × Vitality × Morphology ÷ 10,000
Clinical Significance
Normal Results: Generally indicate good fertility potential
Abnormal Results: May suggest fertility challenges but don't rule out conception
Functional Sperm ≥ 10 million: Associated with better pregnancy outcomes
Multiple Abnormalities: May require fertility specialist consultation

This calculator is for educational purposes only and should not replace professional medical consultation. Sperm analysis results should always be interpreted by a qualified healthcare provider or fertility specialist. Abnormal results don't necessarily mean infertility, and normal results don't guarantee fertility. Multiple factors affect male fertility, and proper medical evaluation is essential for accurate diagnosis and treatment planning.
