During many cases of IVF the patients produce more embryos than needed for pregnancy. In these cases, you can freeze the embryos for up to 5 years. During the 5 years, the patient can choose to transfer them to the uterus for a lesser cost, and without the need to use stimulatory hormonal drugs or to do egg collection procedure. The success rates for this treatment is quite high in our facility, and it closely mimics the success rates of ICSI and other treatments.
