Assisted Hatching

In order for the embryo to implant into the womb and form a pregnancy, it has to 'hatch' from its outer shell. This may not happen in some women who have thicker than usual outer shell in their eggs. To overcome that, we perform the chemical or mechanical technique to increase the chances of success.
The assisted hatching may be advised to women over 39 years and using their own eggs, women who had recurrent failure of embryo implantation (three or more embryo transfers without a pregnancy), women whose embryos exhibit thick zonapellucida and women with elevated FSH levels.
