Superstition keeps a lot of Olympians from boinking. But what does the evidence say?

Consider, if you will, the Olympic Village. It's no wonder that dating apps like Tinder light up the moment the Olympics begin… and that the Village has a reputation as a sort of sex Shangri-La. But despite the condoms that reportedly litter the Olympic Village by the end of the Winter Games--a record 110,000, or 38 per athlete, were provided this year--many will go unused because of pre-game superstitions. Plenty of elite athletes abstain from sex before competing--even though there's no scientific evidence to support their decision from either a physical or psychological perspective. Supposedly, athletes who swipe left on sex before competitions have an advantage on the field. Theories vary as to the exact reason why.
