(CNN) -- A promising way to stop a deadly disease, or an uncomfortable step toward what one leading ethicist called eugenics?

U.S. health officials are weighing whether to approve trials of a pioneering in vitro fertilization technique using DNA from three people in an attempt to prevent illnesses like muscular dystrophy and respiratory problems. The proposed treatment would allow a woman to have a baby without passing on diseases of the mitochondria, the "powerhouses" that drive cells.

The procedure is "not without its risks, but it's treating a disease," medical ethicist Art Caplan told CNN's "New Day" on Wednesday. Preventing a disease that can be passed down for generations would be ethical "as long as it proves to be safe," he said.

"These little embryos, these are people born with a disease, they can't make power. You're giving them a new battery. That's a therapy. I think that's a humane ethical thing to do," said Caplan, the director of medical ethics at New York University's Langone Medical Center.
