You don’t normally associate the game of bridge with doping scandals, but the World Bridge Federation suspended the top-ranked bridge player, Geir Helgemo, for testing positive for synthetic testosterone and the female fertility drug-clomifene.  The World Bridge Federation is a member of the International Olympic Committee and therefore needs to regularly test for performance-enhancing drugs. In case you’re wondering how testosterone could help a player compete, according to a “Testosterone and Chess Competition” study, “researchers have found that physiological responses to intellectual challenges are akin to those of physical challenges.”
