In Vitro Fertilization: Why Are Mock Transfers Done?

In Vitro Fertilization has a number of steps and each will take time, to ensure that the end result is the best possible. The mock transfer is a preliminary stage of the actual transfer of the embryo. This procedure is not performed by all fertility doctors, but may be helpful to ensure that the embryo is being placed in the right location.

Why Mock Transfer

The mock transfer is performed to determine the actual size and direction of the uterus. No actual transfer of embryo will be made, but having some details about the patient's uterus will help the fertility doctor during the actual embryo transfer.

When the Mock Transfer Is Performed

The mock transfer is typically performed on a non IVF cycle, and the best days to do so are between days 3 and 12 of the menstrual cycle. The mock transfer is not a painful procedure, as it involves the insertion of a small catheter into the uterus. However, the patient will be recommended to take some pain relievers such as Ibuprofen one to two hours prior to the procedure. Some patients have reported feeling some cramps during the insertion of the catheter.

The mock transfer takes 5 to 10 minutes and will be performed as an outpatient procedure. Some fertility doctors will perform the mock transfer during an initial consult for the in vitro fertilization procedure (provided the time of the menstrual cycle is right). The mock transfer may also be performed at the time of the cervical cultures.
