Seven Steps to IVF

#6 Embryo Transfer

Embryo Transfer (ET) usually occurs seventy-two hours post-retrieval. The time of the transfer will be designated by the IVF staff. The embryo(s) that is(are) assessed to be developing normally will be considered for transfer. Although a recommendation (3-5 embryos) will be made regarding the number to transfer, the final decision resides with the couple and the physician. Transferring multiple embryos may result in the growth of more than one fetus. If you have extra embryos after the transfer, they will be cryopreserved if they have demonstrated appropriate development, unless you signed the consent to forgo cryopreservation.

The method used for transferring embryos is similar to that of the mock transfer. You will need to drink fluids to fill your bladder before the actual transfer so that we may visualize the uterus by ultrasound during the transfer. ET is performed by inserting a small catheter through the cervical opening into the uterine cavity. The Embryo Transfer is usually a painless procedure. There is a recommended rest period after the transfer. You will be given specific instructions prior to the Transfer regarding your medications, future testing dates, and activity restrictions.

Blood samples will be needed a few days after transfer to determine if hormonal levels are appropriate. Changes in medication or dosage may be prescribed if deemed necessary. An ultrasound will be necessary to assess the abdomen. Within twelve days post-transfer, hormonal levels and a pregnancy test will be done. If a pregnancy has occurred, further testing blood-work and ultrasound will be required to assess normal progression. Patients are generally followed throughout the first trimester of pregnancy.
