using a known donor

A MILLIONAIRE businessman who secretly helped a single friend conceive through IVF has launched a legal fight over custody. In a case that could have ramifications for hundreds of donor conceptions, the man wants the Family Court to rule on whether he is the boy's parent.
Under Victorian law, a man who donates sperm is not considered the father of any resulting children. All donors must sign consent forms agreeing they do not have any legal rights or responsibilities towards offspring.

The courts are all talking about same sex parenting disputes. The Court of Appeal has this week been hearing from a donor applying for contact with his biological son against a lesbian couple who say they feel “bitterness and betrayal” (the case has not yet been decided but you can read the coverage in the Telegraph here).

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.
