Embryo Fragmentation

Embryo fragmentation occurs when a part of the embryo's cells have broken off and are now separate from the portion of the cell containing the nucleus. These fragments are no longer useful to the embryo.

Fragmentation is quite common in human embryos. However, if more than 25% of the embryo is fragmented, it is less likely to successfully implant in the uterine wall and result in a successful pregnancy.

Embryo fragmentation is also called blebbing.
