assisted hatching

Assisted hatching is a technique used in in vitro fertilization (IVF) to help embryos implant into the uterine lining. Normally, an embryo is surrounded by a protective shell. In some cases, this shell may be too thick, making it difficult for the embryo to break through and implant. Assisted hatching involves creating a small opening in this shell using a laser or an acid solution. This technique aims to improve the chances of successful implantation, potentially leading to pregnancy. It is often considered for embryos that appear weaker or have previously failed to implant.
