No sexual content, but there is sometimes sexually explicit comments, aired, when fighters get mad, and they want to show off their bravado to their opponents. It wasn't always like this but as the 90s came around, it started getting more confrontational. Usually stuff like "I'll f--k your girl"
Nothing excessive. There are some off-fight arguments that can get ugly, but it's never really shown too many times. Most of the violence rating is cause of boxing-related blood and gore. Nothing out of purpsoe
On & off. But when it happens it's very graphic and severe. There's a lot of bravado and fighting that happens out of the ring, usually during a Mike Tyson fight.
Occasional smoking by some boxers in-between and before a fight, sometimes a drug reference, but the drug references are never graphic
Given the nature of the show, and the feuds that sometimes dominate the sport, given how competitive it is, sometimes the program could get very intense, and when Larry Merchant interviews some of the fighters, things can get really ugly. Sometimes threats. Nothing too intense though, it's just expected given the nature of the show.
