Groin Strike

Last updated: July 4, 2026

What is a groin strike?

A groin strike, often called a low blow, is any strike that hits the groin area. The Unified Rules of MMA list it as a foul in both men’s and women’s bouts, which means the referee stops the action the moment one lands.

Deliberate groin strikes are almost extinct in modern MMA. Nearly every low blow seen in the UFC today is an accident: an inside leg kick that drifts a few inches too high, a front kick to the body that dips low, or a knee thrown in the clinch (the close-range position where fighters grip each other while standing).

The ban exists for two reasons. A hard shot to the groin can cause real damage, including a ruptured testicle in extreme cases, and a sport built on skill loses credibility if fights can be won by attacking the most sensitive target on the body. Referees and commentators treat it as one of the most serious fouls alongside eye pokes.

How referees handle a groin strike

The referee calls time as soon as the foul is spotted. Under the Unified Rules, the fouled fighter may take up to five minutes to recover, and the fight restarts once they tell the referee they are ready.

A first accidental offense usually draws a verbal warning. Repeated or blatant low blows can cost the offender a point on the scorecards, and a referee can disqualify a fighter for a flagrant one. Grabbing or squeezing the groin is treated the same way as striking it.

The clock is strict. The Association of Boxing Commissions’ committee report on the Unified Rules states that once the five minutes expire, the fight cannot be restarted, and the outcome is determined by the round and time of the stoppage.

What happens if the fighter can’t continue?

An accidental groin strike that ends a fight early is ruled a no contest, meaning neither fighter wins or loses. If the bout has already passed a set point, often halfway through the scheduled rounds, the judges’ scorecards at the time of the stoppage decide the result instead, which is called a technical decision.

An intentional groin strike that leaves the opponent unable to continue is handled differently. The offending fighter loses by disqualification.

The referee, as the sole arbiter of the bout, decides whether a foul was intentional. That single judgment call separates a no contest from a disqualification loss.

Groin strike vs. inside leg kick

Most accidental low blows in MMA start life as inside leg kicks. The two get confused because they travel the same path, but only one of them is legal.

	Inside leg kick	Groin strike
Target	Inner thigh, just above the knee	Groin
Legality	Legal	Foul under the Unified Rules
Referee action	None	Time called, up to five minutes of recovery
Repeat offenses	Not applicable	Point deduction or disqualification

The margin between the two is small. An inside kick aimed at the thigh of a moving opponent can land on the cup instead, which is why the foul appears on almost every major card even though nobody intends it.

Do MMA fighters wear groin protection?

Male fighters must wear a commission-approved groin protector in every professional bout. Most use a cup made of carbon fiber or hard plastic held in place by compression shorts or a jock-style strap, and The Manual reports that some strikers with a kickboxing background prefer metal cups for their extra protection.

Female fighters are not permitted to wear groin protection below the waist under the Unified Rules, though groin strikes remain a foul in women’s bouts and the same recovery window applies.

A cup spreads the force of an impact rather than eliminating it. A clean shot to a well-fitted cup often lets a fighter continue within seconds, while a strike that catches the edge of the cup or slips past it can end the night.

Were groin strikes ever legal in MMA?

Briefly, yes, in the sport’s earliest days. The first UFC event in 1993 prohibited them, the restriction loosened over the following events, and the promotion banned them again at UFC 14 in 1997, three years before the Unified Rules were drafted.

The rule took its modern shape in 2000 and 2001, when the New Jersey State Athletic Control Board led the drafting of the Unified Rules of MMA. The Association of Boxing Commissions adopted those rules unanimously on July 30, 2009, and every major promotion now competes under them.

The five-minute recovery window came straight from boxing. Larry Hazzard Sr., who headed the New Jersey commission that drafted the Unified Rules, told MEL Magazine that boxing’s low-blow recovery period shaped the MMA version, and he still considers five minutes adequate.

Frequently Asked Questions

Are groin strikes legal in any combat sport?

Almost none allow them. Muay Thai bouts in Thailand historically permitted groin strikes, with male fighters wearing cups to soften the impact, but international Muay Thai banned them in the 1980s, and boxing has prohibited low blows since the Marquess of Queensberry Rules.

Do female fighters get the same recovery time?

Yes. The Unified Rules treat a groin strike as a foul in men’s and women’s bouts alike, with the same recovery window of up to five minutes.

Can a fighter fake a groin strike to buy a rest?

Trying to would be its own foul. The Unified Rules list timidity, which includes faking an injury, as a penalizable offense.

Who decides whether a groin strike was intentional?

The referee, who has sole authority over the bout. That judgment determines whether a fight-ending foul becomes a no contest or a disqualification.
