Frozen embryo transfer is a technique where previously-stored embryos are thawed in the media and replaced back into the uterus of the female. The embryo transfer technique is the same as that of fresh embryo transfer. Either the extra embryos are stored or all are frozen and stored to avoid hyperstimulation.
Embryo transfer is a simple procedure, it takes less than 5 to 10 minutes. It is simpler than the IUI procedure, performed in IVF OT under strict aseptic precautions. Prior to embryo transfer, the number and the date of transfer are discussed with the couple. On the day of the embryo, the Patient is called with the half-full bladder. With the help of ultrasound guidance, the selected Embryo is transferred into the uterine cavity without much manipulation. The procedure has to be very gentle, not to injure or cause even slightest of bleeding.
Anesthesia is not required for this procedure and the patient can go home after half an hour of embryo transfer. The selection of embryos to be transferred is very important. The patient can ask for a single embryo transfer or two embryo transfers and can discuss the pros and cones with the doctor.
