Assisted hatching
A lab technique that thins or opens the outer shell of an embryo before transfer, intended to help it hatch and implant.
In plain English
It's a small lab step that makes a tiny opening in the embryo's shell, in theory making it easier for the embryo to hatch out and attach to the womb lining.
Why it matters
