Are embryos people? The answer will determine the future of reproductive medicine

Here is an excerpt:

The goal of this process is to achieve a healthy child, which now occurs at a remarkably high rate. For specific genetic disorders, preimplantation genetic testing can reduce the odds of having a child with a lethal disorder from 25 to 50 percent to less than 1 percent.

Medicine’s ability to culture embryos and select healthy ones has improved dramatically in the last few years. A clinical trial that I led several years ago showed that transferring a single genetically tested normal embryo resulted in the same delivery rate as transferring multiple untested embryos. When genetic testing is performed, it is now standard of care to transfer just a single embryo at a time — gone are the days of risky triplet and high-order multiples after IVF. Actual babies, not embryos, are being spared from dying from the complications of genetic diseases and severe prematurity thanks to the increased use of single-embryo transfer afforded by preimplantation genetic testing.
