NEWS: Trophectoderm morphology may help predict live birth after blastocyst transfer

The selection of blastocysts with the highest implantation potential usually involves the assessment of the appearance of trophectoderm (TE) and inner cell mass (ICM), and the degree of blastocele expansion, as per the morphological grading system developed by Gardner and Schoolcraft. The greatest scores of all these parameters indicate a blastocyst with high implantation rate; however, the independent predictive ability of each parameter is not very clear. A recent and unique retrospective trial has suggested the superiority of TE over ICM as a more significant independent predictor of live birth outcome in blastocyst transfer cycles. Although the assessment of ICM is critical, the researchers concluded on the importance of a strong TE layer for successful hatching and implantation. Read the full story

Study Reports Effective Blastocyst Cyropreservation Using Closed Blastocyst Vitrification System

A recent study has reported the effectiveness of a closed blastocyst vitrification (CBS-VIT) high security (HS) device for the cryopreservation of blastocyts from early cavitating to expanded blastocyst stage. Read the full story
