A cycle of egg freezing involves the same treatment as for conventional IVF, except the eggs are not fertilised or transferred. The eggs that are mature enough are frozen on the day as the egg collection.

During the subsequent cycles,the stored eggs are thawed and proceeded with IVF.The resulting embryos are transferred , using the same procedure as in a conventional IVF embryo transfer. There is no difference in fertilization rate or pregnancy rate.
