After the fertilization of the egg to create the embryo, the next step in the IVF procedure is the implantation of the embryo into the uterus. This procedure is actually fairly simple. It only takes about 5 minutes for the doctor to perform the procedure and it requires no anesthesia or recovery time.
Elective Single Embryo Transfer (ESET)
Generally the procedure used to implant (transfer) the embryo is called an elective single embryo transfer. As it states in the name of the procedure, the fertility specialist will select only one single embryo to implant into the uterus.
The doctor will select the very best looking embryo to implant in order to optimize the chances of success. By implanting only one embryo the doctor eliminates the risk of multiples, (twins or triplets).
For the fertility specialist to decide to perform this procedure the patient must meet certain criteria. She must be no older than 37 years of age. This must be her first cycle of IVF, OR she must have had a previous successful IVF procedure. Finally, the patient must have a high quality blastocyst.
Transfer of the Embryo (Implantation)
For the transfer procedure the fertility specialist will confirm patient identity and embryo match. The embryo will be picked up with a catheter, (large needle) and inserted into the uterus with guidance via sonogram. The image will be displayed on a monitor screen.
The embryo is implanted into the uterine wall with a gentle puff of air. The catheter is slowly removed and then inspected under a microscope to ensure the embryo was implanted. The patient will remain still for several minutes and then given instructions before leaving. After two weeks you will be given a pregnancy test.
