It doesn't deter me if I'm not a carrier of whatever the donor has. The only risk is when your child (who may be a carrier) wants to have their own kids, but they can get screened to be aware of their carrier status. If there's a donor you really like, a genetic counselor can help you understand the risk of using him.
