Hundreds of thousands of frozen embryos sit in U.S. fertility clinics with no legal clarity on custody if couples separate. When Erin Millinder's husband revoked consent to use their embryos after divorce, she pursued a groundbreaking court battle that exposes a legal void affecting millions as IVF use surges—and raises urgent questions about who gets to decide the fate of potential life. Erin Millinder won a New York court ruling giving her custody of frozen embryos despite her ex-husband Adam Rubin's withdrawal of consent, but the case is on appeal and two-thirds of U.S. states have no legal precedent governing embryo custody disputes.
