Every calculator in one place, free and with no sign-up. Results show instantly — we don't hide them behind a form. Each one explains what the number means, where the reference ranges come from, and what it cannot tell you.
A calculator sees three or four figures. A specialist sees your history, your scans, your partner's results, and how you actually responded to treatment. If you're between cycles, changing clinics, or something in your results doesn't add up, a second opinion is the fastest way to find out whether anything would be done differently.
Free first consultation. No obligation to start treatment, and it doesn't affect your care at your current clinic.
These tools provide general information and are not a diagnosis or a substitute for assessment by a qualified clinician. Reference ranges and sources are stated on each calculator. Predictive estimates describe groups of people and cannot predict an individual outcome.

The figure that predicts whether IUI is realistic, better than any single parameter.
Exact calculationArithmetic on the numbers you enter. If your inputs are right, this figure is right.
Total motile sperm count is semen volume multiplied by sperm concentration and the percentage of motile sperm. Most units use 5 to 10 million as the threshold at which IUI becomes realistic; below about 1 million, ICSI is usually the route discussed.
Source — Thresholds vary between units; 5–10 million post-wash is a commonly used IUI cut-off. WHO 2021 reference limits apply to individual parameters, not to TMSC.

Million per mL
Percent moving
That falls in the 20+ band.
Your result of 60.0 million sits in the highlighted band. Bands are reference points used alongside clinical findings — not a diagnosis.
Well within the range where TMSC is unlikely to be the limiting factor. Where difficulty persists, look at DNA fragmentation and female factors.

Highlighted is the stage this measurement belongs to. It is a map of the process, not a schedule — timings vary by protocol and by clinic.
Because it captures how many sperm are actually available and moving. A high concentration in a very small volume, or a normal count with poor motility, both produce a low TMSC — and that is what predicts whether IUI is realistic.
This calculates pre-wash TMSC from a standard semen analysis. Post-wash TMSC, used for IUI decisions, is measured after preparation and is typically lower. Ask your lab which figure they have quoted.
Considerably. Sperm production runs on roughly a 74-day cycle plus two weeks of transit, so a sample reflects conditions from about three months ago — including any illness or fever. A single result is not a diagnosis.

TMSC thresholds are unit-specific and used alongside clinical findings rather than in isolation. A single sample is not a diagnosis. Nothing here is a diagnosis or a substitute for assessment by a clinician.
A calculator gives you a number. These explain what it means, and what it does not.
