In March 2018, Cleveland's University Hospitals announced that a catastrophic failure at its fertility clinic resulted in a tank malfunction that destroyed 2,000 embryos - days after News 5 received information from a source and began digging into what happened. We found patients impacted by the failure who shared with us letters they received from the hospital, where University Hospitals claimed some eggs may be salvaged. Within weeks, however, the hospital admitted the situation was significantly worse. In fact, every single egg and embryo, 4,000 in total, was lost. As soon as the news broke of the failure, WEWS-TV understood the magnitude of this failure for the patients. The entire newsroom mobilized to uncover how this could happen and hold hospital officials accountable.
