The lack of natural growth factors in the fluid in which IVF embryos are grown could have lifelong effects on people conceived this way. That is the implication of a study on mice by Australian researchers, who say preliminary studies of human embryos back their claims.

Why do we care what happens to mice? Because mice are mammals, like humans, and their physiology isn't so different because of our evolutionary similarities. An evolutionary hypothesis that makes babies healthier.
