"For girls, it raises your testosterone so I try to have as much sex as possible before I fight actually," Rousey said on the "Jim Rome on Showtime" show Wednesday night.
"Not with like everybody," she added with a laugh."I don't put out Craigslist ads or anything. But if I've got a steady I'm going to be like 'Yo, fight time's coming up.'"
The mixed martial arts star was responding to a question about what how some boxers abstain from sex before fights.
The 25-year-old American, an Olympic bronze medallist in judo, is 6-0 in MMA with every fight ending in the first round via an armbar submission.
She won the Strikeforce 135-pound title but recently signed with the UFC and will help introduce a women's division to the promotion.
The sex query was part of a 10-question format on the show. One of the other questions was "Ever been in a fight with a guy?”
"Yes. I got in a fight with a couple of guys at the end of 2007 in a movie theatre," said Rousey. "It was four couples, so four guys and one girl tried to get into it. And I had two friends with me. But I was only really handling two guys by myself.
"They sued me for assault because it didn't really go too well for them. I guess if you lose a fight in Santa Monica the next option is to sue. Everyone in the theatre was cheering for me. I was thinking I might have a future in this. It was before the whole MMA thing."Suggest a correction
