This calculator will estimate the male conception rate within 3-5 years for subfertile men based on the man's age and sperm count results (you need to have his spermanalysis results):
- percent motile sperm is normally >= 50%;
- motility grade: none = 1, poor = 2, fair = 3, good = 4;
- oligozoospermia is when sperm density is < 20 million per mL;
- severe oligozoospermia is when the sperm density is <= 10 million per mL.
