Scientists have made a groundbreaking discovery with mice that could pave the way for same-sex parenting in humans. By editing genes in mice using stem cell engineering, researchers successfully created offspring from two male parents who survived until adulthood—a first ever. The breakthrough involves modifying 20 critical genes to prevent imprinting abnormalities, which cause developmental issues when embryos have genetic material from only one parent. This approach could allow humans to create children biologically related to both fathers—but it’s currently prohibited due to ethical and safety concerns. The study highlights the potential of gene editing in regenerative medicine while emphasizing that human applications are still years away.
