A crop of Silicon Valley startups offers the hope of eradicating disease by testing embryos for genetic abnormalities and the potential for future illness. But those tests come with a high price tag and ethical questions about the use of predictive technology to decide who gets born – or not.

Host Elahe Ezadi speaks with Silicon Valley correspondent Elizabeth Dwoskin about the cutting-edge science driving fertility startups, what families who use them say, and how this trend fits into Silicon Valley’s obsession with hacking our health.

Today’s show was produced by Laura Benshoff and Arjun Singh. It was edited by Ariel Plotnick and mixed by Sam Bair.
