In IVF the fertilisation of the sperm happens outside the body. IVF is the method where eggs are pulled from the ovaries and then combined with sperm in a laboratory tray. Fertilization happens on this tray, "in vitro", means "in glass". The fertilized egg is then positioned into the uterus. Embryo Transfer is the final stage of IVF. In this stage once the embryos are created, they will need to be placed in the uterus. Now there will be a two week period of wait which is required after the transfer of the embryo and the initial test for pregnancy. This is an extremely difficult and anxious time for most patients.
