Assisted Hatching: What is it and why does my IVF Clinic do it?

Assisted hatching is a laboratory procedure that is sometimes performed along with in vitro fertilization (IVF) treatment. ⁠

The hope is that assisted hatching might help the embryo expand, implant into the uterine wall, and finally lead to a pregnancy.⁠

During assisted hatching, the outer shell of the embryo is artificially weakened by making a small hole in the zona pellucida.⁠

Assisted hatching may help improve pregnancy chances in women who have failed to get pregnant in previous IVF cycles and those with a poor prognosis (who are not likely to conceive).⁠

If you had PGT performed on your embryos, they were hatched before being biopsied. However, they may be hatched again with the laser after the embryo is thawed. ⁠
