Summary

Morphometric measurement of blastocyst diameter was taken on the day of trophoectoderm biopsy. PGT-A was done using NGS platform, followed by thawing and transfer of euploid blastocyts. Follow up of the Pregnancy and implantation rates is done and recorded to study the correlation between the diameter and reproductive outcomes of the blastocyst.

Detailed description

Blastocyst morphological grading proposed by Gardner and Schoolcraft including the expansion degree, inner cell mass, and trophoectoderm assessment has proved its importance. Blastocyst expansion degree that can presented in diameter is linked to the blastocyst implantation and overall success. In order to evaluate the importance of blastocyst diameter in PGT-A cases, measurements will be taken on the day of trophoectoderm biopsy TE (diameter in μm), followed by TE biopsy using flicking technique. Next, PGT-A will be done using NGS platform and results will be confirmed using PGT-ai. Thawing of euploid blastocyst will take place and expansion degree, survival rate will be recorded. Patient will be followed up for the clinical pregnancy and implantation rates.
