USC's Capron attributes the Wild-Westness of sperm banking to the touchiness of reproductive politics. Liberals, who normally favor medical regulation, are libertarian about reproductive choice. They believe any regulation will limit reproductive freedom. Conservatives don't want to rein in these independent businesses. Also sperm banks exist in a netherworld between medicine and commerce. Because of this political sensitivity and the fish-nor-fowl quality of sperm banks, they have managed to duck the rigorous standards, ethical guidelines, and government supervision that cover every other important area of medicine. It is ruled by rabid customers who will do or pay almost anything to have a baby.
