Minn. company assists in recent birth of twins from 1971 sperm donation
A North Oaks-based company says it played a role in the August birth of twins to a woman artificially inseminated with sperm frozen 41 years ago. ReproTech tells the Pioneer Press that the previous record for a successful live birth using "cryopreserved" sperm was 28 years. The company says the sperm donation was from a Japanese-American war hero who was unable to conceive with his wife, yet wanted to carry on his family's bloodline.
