What patients can expect for percentage of embryos biopsied and normal embryos available for fresh blastocyst transfer when undergoing trophectoderm biopsy with 24-chromosome genetic analysis

Abstract

Trophectoderm biopsy with 24 chromosome microarray-comparative genomic hybridization (aCGH) for preimplantation genetic diagnosis (PGD) is a clinically validated procedure to select chromosomally normal embryos for a fresh transfer during an IVF cycle. The expectation of the percentage of embryos that will be available for biopsy on Day 5, and how many cases result in normal embryos available for fresh blastocyst transfer has to our knowledge yet to be investigated.
