Why do frozen embryos have a higher success rate than fresh embryos ?

A few years ago, everyone believed that fresh embryos were better than frozen embryos . We felt that they had a better chance of becoming a baby ( in scientific jargon, that they had a higher implantation rate.)
However, we are now starting to realise that this is no longer true; and that thanks to vitrification, the success rate with frozen embryos is better ! This may seem counterintutive - but here's why transferring frozen embryos has a higher success rate than transferring fresh embryos.
