Eric Schwartzman who runs a Yahoo group called DI Dads dropped me a line a while back to let me know about an article in USA Today about dads to kids born by donor insemination who are speaking up. It's about dads (and families) who've chosen to tell their children about the way in which they were conceived. Eric himself was interviewed for the article.
I found it interesting that Eric says that the term 'father' is used for the donor and dad for the social parent (the male parent raising the child). I like the separation between formal and functional... I really understand why it's important for these dads to speak up - they're making it legitimate to have children with the help of a donor. This will make it easier for future couples contemplating using a sperm donor and will make it easier for children who were conceived in this way.
When I was a kid, most adopted children didn't know they were adopted. Today, I think it's rare for a child not to know. I doubt that this change will happen as quickly with children born using donor insemination, but the work Eric and others like him are doing seems like a step in the right direction.
