A Frenchman has filed a discrimination suit at Europe’s top rights court over a rule that requires gay men to refrain from having sex for a year before they donate blood, his lawyer said Friday.

Laurent Drelon, 48, has been prohibited from giving blood several times since he first tried to do so in 2004.
