Donor egg success calculator

What are my chances with donor eggs?

Q: Why does my age barely matter?

Because the dominant factor in embryo quality is the age of the egg. Uterine receptivity does decline, but far more gradually than egg quality does.

Q: Are donors anonymous in India?

Yes. Under the ART Act 2021 donors are anonymous, donation is regulated through registered ART banks, and a donor may donate only once. If your home country grants donor-conceived people a right to identifying information at 18, that difference is worth thinking through.

Q: What figures should I ask a clinic for?

Live birth rate per transfer for its own donor programme, the typical donor age range, and how many cycles that figure is based on. A clinic quoting only a general donor success rate is not telling you much.

Why donor outcomes track the donor’s age rather than yours, and roughly what that means.

How this is worked out

Population estimateAn average for people with your inputs, not a prediction for you. Individual outcomes vary widely around it.

Donor egg outcomes track the age of the donor rather than the recipient, because egg quality is the dominant factor in embryo viability. Recipient age affects uterine receptivity, but far more gradually — which is why donor programmes change the picture sharply for people in their forties.

Donor programme outcomes vary substantially between units and are not well captured by any single published figure. Ask any clinic for its own live birth rate per transfer for its donor programme, broken down by donor age.
