I remember when I was a hardcore endurance athlete, I remember reading articles on the pros and cons of sex before competition, and even remember reading stories about how some women athletes would get pregnant just before the games and abort the pregnancy so they could reap all the hormonal and blood level benefits that come with pregnancy.
I did find this article entertaining, and it basically makes the Olympic village look like a giant party with lots of parties and lots of sex, and even quotes a psychologist that says “More sex means more gold.”
