Baby Farms of the Future? Docs Warn of Ethical Issues from New Tech

In the not-too-distant future, scientists may be able to create human sperm and egg cells in a lab dish. In a new paper, researchers at Harvard and Brown universities discuss the theoretical implications of creating sperm and egg cells in a lab dish, referred to as "in vitro gametogenesis," or IVG. IVG is not yet possible in humans — just from a scientific standpoint, many technical barriers remain before human gametes could be made from other human cells, the authors said.
