Stimulation dose interpreter calculator

What does my injection dose mean?

What your prescribed stimulation dose means, and whether it fits your reserve markers.

Daily dose prescribed

From your prescription, e.g. 225

Example answer

225IU per day

150 to 250 IU

The commonest starting range for average ovarian reserve. Most first cycles begin somewhere in this band.

Your numbers

Everything worked out from what you entered.

Prescribed dose: 225 IU per day
Your reserve markers suggest: average reserve
AMH: 2.5 ng/mL
Antral follicle count: 12 follicles
How these fit together: A common dose for average reserve markers.

What each result means

Your result is highlighted. Your own clinic's advice always comes first.

Your resultbelow 150 IU

A low starting dose. Usually chosen for high ovarian reserve, PCOS or a previous strong response, specifically to reduce OHSS risk. Also used in mild-stimulation and natural-modified protocols.

Your result150 to 250 IU

The commonest starting range for average ovarian reserve. Most first cycles begin somewhere in this band.

Your result250 to 375 IU

A higher starting dose, typically for reduced ovarian reserve or a previous cycle that produced few eggs. Above roughly 300 IU the evidence for further gains is weak, so it is fair to ask what the reasoning is.

Your resultabove 375 IU

A high dose. Increasing beyond this point has not been shown to add many more eggs in poor responders, and it raises cost and side effects. Worth asking directly why this dose, and what alternative was considered.

Calculators for what comes next

How this is worked out

InterpretationExplains a result or decision you already have. It recommends nothing.

Reads back the gonadotropin dose you have already been prescribed and places it against normal practice. It does not suggest a dose. Two people the same age can be prescribed doses differing threefold and both be correct — what matters is whether yours fits your ovarian reserve markers.

About this calculator

?What it tells you

Your dose compared with your test results. What your prescribed stimulation dose means, and whether it fits your reserve markers.

✓When to use it

Never — this is your clinician’s decision

iWhat you need

Daily dose prescribed (IU)
Your AMH (ng/mL)
Antral follicle count (follicles)
Your age (years)

!What it cannot tell you

This explains a prescription you already hold. It recommends no dose, and a dose should never be started or changed without your clinician.

Common questions

What actually sets my starting dose?

AMH and antral follicle count estimate how many follicles are available to recruit; age and weight modify it; and previous response outranks all of them. The dose is a prediction made before there is evidence of how you will respond, which is why it is often adjusted mid-cycle.

My dose was changed mid-cycle. Did something go wrong?

Usually not. Scans and blood tests during stimulation show whether the response matches expectation, and adjusting is normal practice. It is worth asking what they saw and what they are now expecting.

Why is my dose different from someone the same age?

Because age is only one input. Two people at 34 with AMH of 0.8 and 4.5 should not receive the same dose — one needs recruitment, the other needs restraint to avoid OHSS.

Is a higher dose better?

Not beyond a point. Above roughly 300 IU the evidence for recruiting meaningfully more eggs in poor responders is weak, while cost and side effects continue to rise.

What should I ask my clinician?

What is my dose based on — AMH, antral follicle count, or a previous cycle? What response are you expecting? At what point would you change it? And if I respond more strongly than expected, would you switch the trigger or freeze all embryos?

Sources

Interpretation only — this reads back a dose already prescribed and does not generate one. Starting dose is set from AMH, antral follicle count, age, weight and above all previous response, then adjusted from monitoring during the cycle. Typical starting ranges are indicative of common practice, not a standard. Your clinician has information this form does not.
