Many donors choose to remain anonymous, but Todd has decided to be a part of his biological children's lives. Since registering on the Donor Sibling Registry, a website that helps children conceived by sperm donations find their half siblings and biological fathers, Todd has met three of his offspring, though he says he could have as many as 10 children.
"When we first got together and met each other, we went to the museum, went to dinner and went to Disneyland," he says. "I bought them all presents for their birthdays. I bought them all presents for Christmas, as well. I also got several Father's Day cards."
Since meeting his children, Todd says his life has become richer. "It's really been wonderful to get to know these kids," he says. "I love them, and I really feel like we're developing a really close family connection."
