Calculators
A set of fertility and pregnancy calculators for patients and clinicians. Each gives an individualised estimate for guidance and counselling — always alongside the advice of your own clinical team.
- Estimate probability of natural conception Chance of conceiving naturally within 12 months, from the validated Bensdorp (2017) prognostic model.
- Estimate ovarian reserve (antral follicle count) Where an antral follicle count sits against age-based percentiles — an ovarian-reserve nomogram.
- Calculate IVF stimulation cycle dates Plan an IVF stimulation cycle — the key monitoring and trigger dates for antagonist or long-agonist protocols.
- Estimate probability of IVF live birth Cumulative chance of a live birth from a stimulation cycle, following the chain from AFC through eggs, MII, blastocysts and euploid embryos.
- Calculate frozen embryo transfer dates Schedule a medicated or modified-natural frozen embryo transfer, with monitoring, blood-test and scan dates.
- Calculate pregnancy due date Estimated due date and current gestational age for a pregnancy dated from the embryo transfer.
