Last Saturday’s Wall Street Journal featured an article as fascinating as it was disturbing: “What If Men Could Make Their Own Egg Cells?” It discussed the work of Matt Krisiloff, CEO of Conception Biosciences. Krisiloff and his team are working on producing human embryos from genetic material that is not connected in origin to an egg or a sperm. Indeed, the article begins with a quotation from a Japanese biologist, Katsuhiko Hayashi, who believes that it will be possible to make human eggs from skin cells within a decade.

While the science is surely impressive, it raises all kinds of ethical questions. The article nods to the fact that developments in reproductive technology have transformed the notion of parenthood. Though it does not use the term, a contractual notion of parenthood as functional rather than natural seems to be emerging in the West.
