Assisted Hatching

Like oocyte donation, assisted hatching is a procedure done in conjunction with IVF. It is believed to enhance embryo implantation by assisting interaction between the embryo and the lining of the uterus. To date routine use is not recommended, however, it may improve implantation rate in frozen embryos of older women.

How It Works

In the process of assisted hatching, the embryo is held with a holding pipette. A smaller pipette containing an acid solution is then used to make a small hole in the zona pellucida. The embryo is then released and transferred as in regular IVF procedures.
