Designer baby tech conceives ethical quandries

Parents - including perhaps same-sex couples - may soon be able to select their ideal embryo from several dozen potential candidates created using their cells, experts say.

The possibility, which some researchers say could occur in the next 20 to 40 years, sets the stage for what ethicists warn would be a political and moral quagmire.

"The majority of babies of people who have good health coverage will be conceived this way,” predicts Henry Greely, a Stanford University law professor who works in bioethics.

Scientists have shown that in mice, they can turn ordinary cells into sperm and eggs and scientists are reviewing the potential for the technology to apply to humans as well. If proven viable in humans, the technique could become a powerful infertility treatment, permitting genetic parenthood for people who can't make their own sperm or eggs.

It also would mean that a woman who wants to become pregnant could produce dozens of extra eggs per attempt than with the current procedure of harvesting some from her ovaries.

The technology could even open the door to same-sex couples having children genetically related to both of them, though the additional twist of making eggs from men or sperm from women would be a huge biological challenge.

Greely, who lays out his ideas in a book called The End of Sex and the Future of Human Reproduction, calls his vision "easy PGD”, or prenatal genetic diagnosis. But the drawbacks, critics warn, could be severe.

For example, some have asked, once the genetic profile is done, could it come back to haunt a child if, say, a life insurer or nursing home demanded to see it to assess disease risk? How would the large number of rejected embryos be handled ethically and politically?

Lori B. Andrews, a professor at the Chicago-Kent College of Law, summed up her views in a review of Greely's book.

"The idea of easy PGD,” she wrote, "should make us uneasy indeed.”

Also worrisome is the so-called Brad Pitt scenario: We all shed a bit of sloughed-off DNA every day, like on the lip of a coffee cup. Such discarded material could be secretly snatched up to turn an unwitting celebrity into a genetic parent.
