Analysis of Surplus Cryopreserved Blastocysts in Fresh Donor Oocyte Cycles.

ABSTRACT:

Importance

Excess cryopreserved embryos present financial, logistical, and ethical constraints on patients and fertility clinics that are further complicated by the recently evolving US judicial landscape that may alter the legal status of frozen embryos and limit disposition options. It is therefore important to consider limiting the number of supernumerary embryos created from fresh donor oocytes.

Objective

To determine the optimal number of fresh donor oocytes to fertilize to achieve 1 live birth while minimizing supernumerary blastocysts.

Design, setting, and participants

This cohort study used data from recipients of fresh donor oocytes at member clinics of the Society for Assisted Reproductive Technology Clinic Outcomes Report System (SART CORS) between January
