Stanford law professor and bioethicist Hank Greely predicts that in the future most people in developed countries won't have sex to make babies. Instead they'll choose to control their child's genetics by making embryos in a lab.
On KQED's Forum program, Michael Krasny spoke with Greely about his new book, The End of and the Future of Human Reproduction. Greely highlights the ethical and legal questions that might arise in the future's reproductive paradigm.
Krasny: There are a lot of new advances, technology and so forth. We reached the point where you get some sperm donor and a little piece of skin and you're in business because of stem cells.
Greely: My book argues that two different biomedical innovations coming from different directions and not really propelled by reproduction are going to combine here. One is whole-genome sequencing, and the other is what I call easy PGD, preimplantation genetic diagnosis, [that] is, getting rid of egg harvest ... which is unpleasant, dangerous and really expensive.
This ties in with in vitro fertilization also being not as onerous as it has been in the past.
What I think is going to happen, we'll be able to take some skin cells from anyone and turn them into any cell type. Make these into eggs or and that is going to make IVF much easier, cheaper and less dangerous.
You [can] decide, "Well, I want these traits," and it becomes a selective process.
Yes, I think we will see an increased and broad use of embryo selection. I would be careful to set the time frame at 20-40 years. I think we'll actually see a world where most babies born to people with good health coverage will be conceived in the lab. People will make about a hundred embryos, each will have its whole genome tested, and the parents will be [asked ... "Tell] us what you want to know and then tell us what embryo you want."
This could bring down health care costs, and it is also good for same- couples, isn't it?
Well, yes and maybe. I think it should bring down health care costs, and, in fact, one of the advantages to it is that it would be so beneficial for public health care costs that I think it would be provided for free. If it costs say, $10,000 to start a baby this way, 100 babies is a million dollars. If you avoid the birth of one baby with a serious genetic disease, you've saved $3 [million to] $5 million. The same-sex issue, I think that's going to work, but that's another jump. That would be taking a skin cell ... from a woman and turning it into a sperm. I think [it's] probable, but that hasn't been done yet.
