Implanted embryos better frozen than fresh, study says

A study shows babies born from implanted frozen embryos had higher birth weights than fresh embryo implant babies. It's believed that frozen embryos did better because only the strongest embryos survive the freezing and thawing process.

Freezing embryos also allows couples to have several cycles of treatment from one egg collection.

The results of this study were presented at the European Society for Human Reproduction and Embryology meeting in Barcelona.
