Oocyte Number Estimator - ONE

ONE estimates the minimum number of mature oocytes needed for obtaining at least one euploid blastocyst.

How ONE works

ONE (Oocyte Number Estimator) is a tool based on the ART Calculator predictive model published by Prof. S. Esteves 1,2. ONE provides personalized information to facilitate treatment expectation discussion, communication and planning between healthcare professionals and patients. The application can be used in two different settings: pre-treatment and post-treatment.

Main_Pre-treatment

The model estimates the number of mature (MII) oocytes needed to obtain at least one euploid blastocyst for transfer in infertile couples undergoing Assisted Reproductive Technology.

Main_Post-treatment

The model computes a revised estimate of probability of obtaining at least one euploid embryo when the number of mature oocytes obtained after one or more oocyte retrieval cycles is provided.
