IVF creates an environment which allows for maximal interaction between as many eggs and sperm as possible, multiple embryos are produced, the best of which can then be transferred directly into the uterus under highly optimized conditions.

For a woman to conceive with IVF, she needs healthy eggs, appropriate numbers of sperm from her partner, or donor, and a normal uterus. Under these optimal conditions, IVF yields the highest pregnancy rates available.
