Selective Single Embryo Delivery Using HEED and SEED Optimizing Results from IVF While Reducing Risks and Side Effects

Although embryo transfer technique has been known to be a major limiting factor in accomplishing a successful live birth from IVF, there has been little progress made in embryo transfer technique in the past 40 years. Here we describe novel techniques of HEED and SEED that will optimize results and reduce risks and side effects from IVF procedures. Using a targeted single embryo delivery whether by HEED or SEED will standardize embryo transfers by allowing a visually confirmed placement of the embryo. In addition, they allow for gentle placement of the embryo at optimum zone(s) of transfer under direct visual placement. Embryo delivery by HEED is used for embryo transfers at cleavage and more advanced stages of embryo development whereas SEED is strictly for blastocyst implantation. SEED will help alleviate problems with embryo implantation and minimize ectopic pregnancies and lost embryos. It will also minimize occurrence of placenta previas from IVF. These benefits with the reduced majorpitfalls of the procedure will greatly enhance maternal health and reproductive safety.
