Frozen embryo transfer and process

Have you ever wondered why do couples freeze their embryos?

Surplus embryos from an IVF cycle are frozen to give couples multiple chances for implantation, depending of the number of embryos they’ve got. Frozen embryo transfer (FET) is a procedure whereby frozen embryo is thawed and transferred back to the woman’s uterus to achieve pregnancy.

FET may have a good chance of implantation compared to fresh embryo transfer. This is because in fresh embryo transfer, the fertility drugs used to stimulate ovaries during IVF may not create an ideal environment for implantation. With minimal or no use of fertility drugs in FET, the hormonal environment may be more physiologically similar to a pregnancy conceived naturally.
