The Reproduction Revolution: Lab-grown Sperm and Eggs Hold Huge Promise and Peril.

Scientists are exploring the potential of in-vitro gametogenesis (IVG), a process that could create human eggs and sperm in a laboratory from any cell in a person's body. While the technology is still years away from being available for humans, researchers have already perfected IVG in mice. IVG could be life-altering for individuals struggling with infertility, but it also raises ethical, moral, and regulatory concerns. The ability to create a limitless supply of IVG embryos combined with gene-editing techniques could lead to the creation of "designer babies." The FDA is exploring the implications of IVG, but Congress currently prohibits the agency from considering proposals involving genetically manipulated human embryos.
