Evidence-based calculators to help you understand your fertility journey
Welcome to Fertility Numbers – a collection of data-driven calculators designed to help individuals and couples navigate their fertility and IVF journey with clarity and confidence.
Our calculators are based on published research and clinical data, providing you with personalized estimates for various aspects of fertility treatment. Whether you're exploring your options, preparing for IVF, or managing pregnancy expectations, these tools offer insights grounded in real-world outcomes.
Select a calculator below to get started:
Estimate expected oocyte (egg) yield based on your Anti-Müllerian Hormone (AMH) levels and Antral Follicle Count (AFC). This tool helps predict how many eggs might be retrieved during an IVF cycle and estimates potential euploid embryo outcomes.
Calculate the expected number of euploid (chromosomally normal) embryos based on your age and AMH levels. This comprehensive calculator provides uncertainty ranges and visualizes the IVF process from egg retrieval through to euploid embryos with detailed breakdowns at each stage.
Visualize the IVF pipeline from eggs retrieved through to live births. This simplified calculator shows expected attrition rates at each stage: mature eggs, fertilization, blastocyst formation, euploid embryos, and live births. Perfect for understanding realistic expectations at each step.
Understand miscarriage risk based on maternal age and gestational week for naturally conceived pregnancies. This calculator provides risk percentages and visualizations showing how risk changes across different ages and weeks of pregnancy. Note: This is for natural conception only, not IVF with PGT-A.
These calculators are for informational and educational purposes only. They are not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified healthcare provider with any questions you may have regarding your fertility or medical condition.
Individual results vary significantly based on numerous factors including but not limited to: overall health, specific fertility diagnoses, clinic protocols, embryologist skill, and many other variables. The estimates provided are based on population-level statistics and may not reflect your personal situation.
Never disregard professional medical advice or delay in seeking it because of something you have read or calculated using these tools.
