Sperm donor 9623 looked good on paper. Ontario couple Elizabeth Hanson and Angela Collins thought they had found the perfect father for their baby. Seven years after their son was born, Collins and Hanson discovered that donor 9623 was a college dropout with schizophrenia, a narcissistic personality disorder and a criminal history. He had spent eight months in prison for burglary, and 10 years on probation. The sperm bank had inadvertently included the donor's name, Christian Aggeles, in an email to the couple.
