People always say the World Cup is a nightmare for women, but a carnival for men. Men pay more attention to soccer during the World Cup they say, and often forget to love their girlfriends and wives. However, a recent medical study rejects this idea completely, according to a report from the French newspaper "Nouvelles D'Europe".

The study shows that soccer is a sort of "sex stimulus", which doesn't stop emotion between lovers but actually increases it.

Seventy percent of couples who watch soccer games together can produce fun sex with each other after because all the excitement on the soccer pitch stimulates their nerves, acting as a kind of "love potion," the German newspaper "Bild" reported recently.

For men, the male hormone rises as they watch a soccer game with their lovers, especially a game with more goals, which will make them even more energetic.

Similarly, a soccer game can also make women more excited. Women really enjoy watching soccer players running on the pitch, looking at the players' unique eyes and seeing their uniforms wringing with sweat. If they see good-looking stars like Beckham, Figo or Ballack in a game, they become even more excited.

The hormone in womens' bodies also increases if they see their lovers sweating because of a good match. However, women always try to interrupt men watching an exciting game, which really makes men angry.

The researchers also found that a soccer game can have the same effect on single viewers. Forty-one percent of males and 35 percent of females are pleased to have sex after a soccer game, according to the report.

So couples prefer to watch a soccer game for free, rather than spend money to see a movie.
