New Technologies to Improve Embryo Assessment

Fertility & Reproduction, 2023
Embryo quality is a key factor in determining whether an IVF cycle will result in a live birth. Current approaches for assessing embryo quality are subjective (morphology) or invasive (biopsy) and are not always predictive of live birth.

An increase of phosphatidylcholines in follicular fluid implies attenuation of embryo quality on day 3 post-fertilization

BMC Biology, 2021
Background Although oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate embryo quality based on the metabolites related to the oocyte. With quantification of the follicular fluid (FF) metabolites,
