Niki and Brian Schaefer credit their fertility doctor for giving them their two children.
A freezer malfunction at University Hospitals in Cleveland over the weekend left 2,000 eggs and embryos in a questionable state.
The Schaefers decided to donate their four remaining embryos to one of the affected families.
"This process is the answer to the prayers of people who just want a family," Niki Schaefer said.
The malfunction is affecting more than 700 patients.
