Brief 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.

Embryo Grade
Embryo grade for PGT-A confirmed euploid embryos
6 months
Eligibility Criteria
Patients who have completed IVF egg retrieval with PGT-A testing at a fertility clinic in The Prelude Network (US clinics, excluding NYU).
You may qualify if:
- Patients who have completed IVF egg retrieval with PGT-A testing at a fertility clinic in The Prelude Network (US clinics, excluding NYU)
- PGT biopsy was conducted in 2023,
- PGT biopsy was performed on blastocyst stage embryo,
- PGT-A result is euploid.
You may not qualify if:
- PGT-A result is mosaic,
- Embryos in which PGT-M was done and were found to be carriers of the mutation,
- Embryos in which PGT-SR was done and were found to be carriers of the structural rearrangement.
