Assisted Hatching

 Hatching blastocyst

For more information see the Assisted Hatching Fact Sheet.
Assisted hatching is a process in which scientists create a hole in the shell (zona pellucida) surrounding the embryo prior to embryo transfer.  The hole is created using a laser light beam. It is believed to make it easier for an embryo to ‘hatch’ out of the zona pellucida so that it can implant into the lining of the uterus. In women who have a reduced chance of pregnancy, there is evidence that assisted hatching improves the pregnancy rate by about 30-50%. 

There are limited studies available on assisted hatching but women who have a reduced chance of pregnancy, such as women with severe endometriosis, women who have had two or more past unsuccessful embryo transfers, or women who have an elevated FSH (follicle stimulating hormone) level and/or reduced ovarian reserve may benefit.  Women over 40 may also benefit from assisted hatching. Some studies suggest that assisted hatching is also beneficial to frozen-thawed embryos.
