FROZEN EMBRYO TRANSFER  - (FET)

After embryo(s) One (or more) is/are selected for thaw they are transfer to the uterine cavity. Embryos are placed in the uterine cavity with a thin tube (catheter). Ultrasound guidance may be used to help guide the catheter or confirm placement through the cervix and into the uterine cavity. Although the possibility of a complication from the embryo transfer is very rare, risks include infection and damage to or loss of the embryos. Not all embryos become pregnancies and not all pregnancies are normal or grow in the correct place. Tubal (ectopic) pregnancy can occur.

​

The number of embryos to transfer is an important decision. The age of the woman and the appearance of the developing embryo are two factors which have significant influence on the likelihood of pregnancy and the risk of multiple pregnancy. It is possible to develop more fetuses than the number of embryos transferred if one (or more) of the transferred embryo(s) split into “identical” twins. It is critical to discuss with your physician the number of embryos to be transferred before the transfer is done.

​

• After a few days of development, the best developed embryo(s) is/are selected for transfer

• The number of embryos transferred influences the likelihood of pregnancy and the risk of multiple pregnancy

• The age of the woman who provided the oocytes (eggs) and the appearance of the developing embryo(s) have significant influence on pregnancy outcome

• Extra, normally developing embryos that are not transferred can be frozen for potential use in future
