When not all of the embryos created during an in vitro fertilization cycle are transferred, they can often be frozen, or cryopreserved, to be used in a future treatment cycle. Embryos are also frozen as a form of fertility preservation in some cases, such as prior to starting chemotherapy. The frozen embryo transfer process is very similar to the process of a fresh embryo transfer, except that the hormonal preparation for the procedure varies somewhat. Below, we will take a look at what you can expect during a frozen embryo transfer, including the length of the procedure.

How Frozen Embryo Transfer Works

During a frozen embryo transfer, the frozen embryo is thawed and then transferred to the uterus in hopes of producing pregnancy. Prior to the procedure, steps are taken to ensure that the uterus is optimally prepared to receive the embryo, including diagnostic tests to evaluate the uterus and the administration of fertility medications to prepare the uterine lining. Lupron, estrogen, and progesterone are used together to prepare the uterus, and the process is monitored in the office frequently. In addition, the embryos will be evaluated to ensure that they survived the thawing and that they are normal before they are transferred.

Apart from these steps, the process of transferring a frozen embryo is nearly identical to the process of transferring a fresh embryo. During the procedure, the physician inserts a thin, plastic tube, or catheter, through the cervix into the uterus. Through this catheter, the embryos are deposited into the uterus. This process can be somewhat uncomfortable, but it should not be painful.After the procedure, the patient will rest in the room for 30 minutes before going home, as most patients feel better if they rest for a while. It is perfectly safe to perform activities like exercise and to have sex afterwards, but many patients prefer not to do so. In about a week, it will be possible to determine whether or not pregnancy has occurred.‍

Procedure Length

‍A frozen embryo transfer is a fast procedure that can be performed in the fertility clinic in about 15 minutes. Once the time to check in at the office and the rest time after the procedure are added in, the office visit as a whole should take well under 2 hours. The process of preparing for the transfer with medication and checkups takes much longer than the procedure itself.If you are interested in treatment for your infertility, or in fertility preservation, Dr. Randy Morris would be happy to hear from you.
