Short answer
Two tools are available. The semen analysis decoder compares optional figures with WHO reference limits used by NICE. The total motile sperm count calculator multiplies volume, concentration and motility. Both are educational. Neither stores what you type.
Key takeaways
- Empty fields are ignored. Zero is a real number and will be interpreted.
- A result inside the reference range is not “fertile”.
- A result below a reference value is not “infertile”.
- Read the method pages before you rely on a single figure.
