Sadegh Eivazi: Hatching Blastocyst Demonstrating Active Expansion and Initiation of Zona Escape
Sadegh Eivazi, Embryologist at Payambaran Hospital, shared a post on LinkedIn:
“Hatching blastocyst demonstrating active expansion and initiation of zona escape.
This image captures a blastocyst at the hatching stage, where trophectoderm cells begin emerging through the zona pellucida. Hatching represents an important developmental milestone prior to implantation and reflects the dynamic interaction between embryo quality and developmental progression.
Every embryo follows its own developmental timeline, and morphology remains one of several parameters considered during embryo assessment.”
