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.
