Clinical Trial Summary

Background: Advanced maternal age (AMA) is associated with a reduction in live birth rate (LBR) after ART cycles. The main reason for this reduction is the lower number of oocytes aspirated, the number of developing embryos and the low number of euploid embryos available for transfer. The impact of age on success rates after the transfer of an euploid embryo has been a matter of discussion, with a recent meta-analysis showing a reduction in LBR after the transfer of an euploid blastocyst to women of AMA (1). There could be many reasons for this reduced LBR but they can be categorized into two broad categories - the uterus (including the mother's health) and the embryo (including the oocyte and the sperm). It is possible that factors associated with reduced embryo quality would manifest in a lower embryo grade.


Clinical Trial Description

Objective: To study if there is an association between advanced maternal age and lower embryo grading of euploid embryos. Hypothesis: Advanced maternal age is associated with a lower embryonic grade in euploid embryos. Study Design: This is a retrospective cross-sectional study of euploid embryos from patients who have completed IVF with PGT-A testing at a fertility clinic in The Prelude Network (US sites only). A comparison of embryo grade between different age groups (<35, 40+) will be done after controlling for baseline demographic characteristics. ;
