A woman's eggs are surrounded by a shell-like substance. Once an egg is fertilized, the resulting embryo in its earliest stages develops within the confines of the shell. When the embryo reaches the uterus it must break out of the shell in order to make contact with the lining of the womb (endometrium). Assisted embryo hatching is a technique which helps to open the shell surrounding the egg just prior to its being placed in the woman's uterus following in vitro fertilization. In some women helping the embryo to break through its shell may improve the chances of an IVF pregnancy.
