I totally believe in Single Embryo Transfer for IVF. In order to improve and maximize the chances for implantation we must be sure that we place the single embryo at the "Maximal Implantation Potential (MIP) Point". This requires an upgrade of the ultrasound guidance to "3D/4D Ultrasound Guided Embryo Transfer". Using this new technique could increase pregnancy rates by more than 10%. This way we can reasure our patients and ourselves that we did the best we could.
