Most 15-year-olds don’t even think about having babies of their own someday, but Alex Powell was forced to start thinking about his future as a parent very early on. The man was just a teenager when he was diagnosed with lymphoma. His doctor advised him to donate and freeze his sperm, as the chemotherapy will most likely diminish the chances of having a baby in the future. The chemo left him infertile, but 23 years later, the man became the father of a beautiful baby boy. The baby entered the Guinness World of Records, as he was conceived from the world’s oldest sperm.
