Title: Fertility PLAN: Improving counseling tools for decision-making around planned egg freezing
Abstract: Planned egg freezing is increasingly marketed as a way for women to preserve fertility, yet the tools used to quantify its potential benefit are often based on strong assumptions. Widely used calculators for predicting cumulative live birth treat each egg as an independent trial with equal probability of resulting in live birth. In this applied talk, I will describe work-in-progress on the development of Fertility PLAN (Fertility Predictor for Live birth via Assisted reproduction or Natural conception), a tool designed to support more informed decision-making around planned egg freezing.
Using data from the Society for Assisted Reproductive Technology Clinical Outcome Reporting System (SART CORS), I reframe the prediction problem using a discrete time survival analysis framework, where the “time” scale is the number of thawed eggs. I compare the standard “equal-and-independent eggs” approach with a discrete-time hazard model and introduce an extension that treats having no frozen eggs left to thaw as a competing event.
