With IVG, creating life no longer would require a man and a woman: Two men could make a baby biologically related to them both using the skin cells of one to make an egg, and the sperm of the other. A woman could make a baby by herself using her cell-turned-sperm and her egg, almost like cloning. A group of three or four people could create a baby by creating two embryos, and then taking an egg from one and a sperm from the other, creating another embryo with multiple parents. Such scenarios inevitably would affect the traditional understanding of parenting. The article also addressed the potential for “unauthorized” use of biomaterials: Someone retrieves a skin cell from a hotel room bed or bathroom, creating a baby biologically related to someone without their knowledge.
