children of sperm donors

From a recent post on Connect It: http://connectitblog.blogspot.com/2011/07/feeling-lonely-with-yourself.html

There is no evidence that lesbians’ children are hurt or damaged by meeting their sperm donor fathers, a small study says.
The study, by researchers at the University of Amsterdam in the Netherlands, used data from the US National Longitudinal Lesbian Family Study.

Seventy-eight teenagers were studied, Reuters reports.

A third of the donors knew their offspring, just over a third were permanently anonymous and 18 could be contacted once the child turned 18.
