You don’t. This is a silly story that’s only making the news because scare stories about reproductive technology always do. The major sperm banks already provide a lot more genetic information on donors than most people would have for a man they’re marrying after knowing him for a decade. Eventually, when DNA testing becomes much cheaper and more efficient, and more genes have been identified, it will make sense to do full genome screens on donors, and it will also make sense for everyone to have a full genome screen done on themselves, even if they’re not planning to have children. But for now it doesn’t.
