One professor claims that future humans will be made from skin cells and prescreened for things like hair color and sex.
In the future, when a couple wants to reproduce, “they will not make a baby in a bed or in the backseat or a car, or under a ‘Keep Off the Grass’ sign,” says Henry Greely, the director of the Center for Law and the Biosciences at Stanford Law School.
Instead, they will go to a clinic. Using stem cells from the couple’s skin or other non-reproductive organs, scientists will be able to make eggs and sperm, which will be combined into embryos. “Each of those embryos will have its own gene sequence,” Greely says. “The parents will be asked: ‘What do you want to know about these embryos?’ And they’ll be told.”
Twenty or 30 years from now, parents will be able to screen their potential kids for genetic abnormalities, pre-disposal to disease, sex, and even cosmetic features like hair, eye, and skin color, Greely claims. The new way of baby-making will save women the pain of going through fertility treatments, he says, and it will prevent disease, save health-care costs, and give non-traditional families more chances to have children. If this reproductive future comes to pass, it will also come with a tangle of moral, legal, and medical questions—ones that won’t be easy to resolve, despite what Greely may think.
