Formula Used
Estimated per-cycle rate = age baseline × diagnosis factor × cycle medicine factor × timing factor × tubal factor × follicle factor × lining factor × sperm count factor × motility factor × morphology factor × BMI factor × duration factor × previous cycle factor.
Cumulative estimate = [1 - (1 - per-cycle probability)number of cycles] × 100.
The final value is limited between 1% and 30% per cycle. This keeps the result inside a practical educational range.

About this IUI Success Rate Calculator
This tool gives an educational estimate for an IUI cycle. It is made for quick planning, not diagnosis. IUI results can change because age, egg quality, ovulation, semen quality, tubal status, timing, and medicines all matter. A clinic can measure these factors more accurately than any online form.
Why the Estimate Changes
The calculator starts with an age based baseline. It then applies practical modifiers. A younger age group usually receives a higher baseline. Mild male factor, reduced ovarian reserve, long infertility duration, or weak post wash sperm numbers can lower the estimate. Good timing, open tubes, suitable follicle response, and adequate lining can raise it within safe limits.
How to Read the Output
The percentage is a planning range for one cycle. It is not a promise. A low value does not mean treatment cannot work. A high value does not mean pregnancy will happen. The cumulative value uses the same per cycle estimate across several planned cycles. Real life cycles are not identical, so the cumulative number is only a guide.
Clinical Use
Use the result to prepare better questions. Ask your clinician whether the selected inputs match your report. Confirm semen values after washing. Confirm follicle count by ultrasound. Confirm whether one or both tubes are open. Discuss whether natural, oral medicine, or injectable stimulation is suitable for your case.
Safety Notes
More mature follicles can improve chances, but they may also raise the risk of twins or higher order pregnancy. Very thin lining, blocked tubes, severe male factor, or advanced age may need a different plan. Do not change medicines, trigger timing, or cycle decisions because of this page alone.
Best Practice
Enter realistic values from the same cycle. Avoid guessing semen results from old tests. Save the CSV or PDF report for your appointment. Repeat the calculation when the clinic updates your follicle scan, lining thickness, or washed motile sperm count.
Privacy and Limits
The page calculates after submission and can also export visible results. Keep personal medical details private when using shared devices. Clear the form after printing. The model is intentionally simple, so unusual diagnoses, donor sperm plans, medicated protocols, or repeat losses require direct medical review.
FAQs
Is this calculator a medical diagnosis?
No. It is an educational planning tool. It cannot replace a fertility specialist, ultrasound review, semen analysis, tubal testing, or personalized treatment advice.
What does TMSC mean?
TMSC means total motile sperm count. For this calculator, enter the post wash value in millions, because washed sperm is commonly used for IUI planning.
Why does age affect the result?
Age is strongly linked with egg quantity and egg quality. The calculator starts with an age baseline, then adjusts for other cycle details.
Can medicine improve IUI chances?
Medicine may improve chances for some people by supporting ovulation or follicle development. It may also increase multiple pregnancy risk, so clinic guidance matters.
Why are follicles included?
Mature follicles show how many eggs may be available. More follicles can raise the estimate, but too many can raise twin or higher order pregnancy risk.
What if my tubes are blocked?
IUI usually needs at least one open tube. If tubal blockage is known or suspected, talk with your clinician before relying on an IUI plan.
Why is the cumulative estimate not guaranteed?
The cumulative estimate assumes the same chance in each cycle. Real cycles vary because follicles, timing, semen quality, and medicines can change.
Should I save the report?
Yes. The CSV or PDF can help you discuss inputs with your clinic. Do not use it to change treatment without medical advice.
