Assisted Hatching
Assisted hatching – Hatching is a process by which the fully developed embryo comes
out of its shell (zona pellucida) and starts communicating with the uterus. Under
certain circumstances, like thick shell, (in case of endometriosis or due to defective
oogenesis), hardened shell(frozen-thawed embryos) etc. artificially starting the
hatching process helps embryo to implant. In this process, part of the shell is
chopped off carefully using laser machine.
