From Norwegian national newspaper "Aftenposten" on May 22, 2009:  

Translated into English

I grew up having a sperm cell as a father and can tell lesbians and the adventurous that it has not been fun at all. One is and remains a person without a history and without an answer when the topic of fathers is mentioned, and that is often! It is easier to refer to an adoption or a death. But a father without a name! I can promise you that it hurts! It will never be cool. Neither will it ever be "common."  

Even a desired and loved child has a need for parents of both sexes. Life itself has convinced me that living with a mother and a father makes one mature for the choices one must make as a young adult, make in love for a person of the opposite sex. I regard anonymous sperm donation as a psychological experiment I that I would never impose on anyone.
