While mixed martial arts is primarily a male dominated sport, it does have female athletes.^[1][2][3] For instance, Female competition in Japan includes promotions such as DEEP Jewels. Now defunct promotions that featured female fighters were Valkyrie, and Smackgirl.^[4] Professional mixed martial arts organizations in the United States that invite women to compete are industry leader Ultimate Fighting Championship, the all female Invicta Fighting Championships, Resurrection Fighting Alliance, Bellator Fighting Championships, and Legacy Fighting Championship. Now defunct promotions that featured female fighters were Strikeforce and EliteXC.^[5] There has been a growing awareness of women in mixed martial arts due to popular female fighters and personalities such as Amanda Nunes, Megumi Fujii, Gina Carano, Cristiane "Cyborg" Santos, Ronda Rousey, Miesha Tate, Holly Holm and Joanna Jędrzejczyk and among others.^[6] Carano became known as "the face of women's MMA" after appearing in a number of EliteXC events.^[7][8][9] This was furthered by her appearances on MGM Television's 2008 revival of their game show American Gladiators.^{[10][11][12][13]}

The UFC's decision to allow female fighters in the organization, to promote the dominant fighter Ronda Rousey, is often cited as the reason women's mixed martial arts became known to the general public.^[14] Rousey won the Best Fighter ESPY Award at the 2015 ESPN ESPY awards, beating out noted fighters such as Floyd Mayweather Jr., and becoming the first UFC and MMA fighter to win the award.^[15]

In Japan, female competition has been documented since the mid-1990s. Influenced by female professional wrestling and kickboxing, the Smackgirl competition was formed in 2001 and became the only major all-female promotion in mixed martial arts.^[16] Other early successful Japanese female organizations included Ladies Legend Pro-Wrestling, ReMix (a predecessor to Smackgirl), U-Top Tournament, K-Grace, and AX.^[17][18]

Ronda Rousey was a female fighter who sparked the popularity of women fighters. When she signed with the UFC in 2012, female fighting was not very popular and was not considered a sport for women. Ronda Rousey was able to open many people's eyes and prove Dana White, the president of the UFC very wrong. Ronda Rousey was the face of UFC and the highest-paid fighter for a very long time. In addition to being an Olympic medalist, Rousey also won back-to-back Pan American Championship gold medals. It was surprising to many people how charismatic and talented Rousey actually was. Every day, female MMA fighters are becoming more popular and getting more viewers^[19]

The traditional MMA rules have often been adjusted for female competitions because of safety concerns. In Japan, ReMix prohibited ground-and-pound and featured a 20-second time limit for ground fighting. This rule remained following ReMix's 2001 re-branding as Smackgirl, though the time limit was extended to 30 seconds. The rule was abolished in 2008.^[33]

In the United States, women's bouts organised by EliteXC saw three-minute rounds while those of Strikeforce were originally of two minutes' duration.^[34] These lengths compare to the more usual five minutes for men.^[35][36] Strikeforce later changed this rule to allow for five-minute rounds.^[37][38]

Another form of rule differentiation is a change in both weight limits and weight classification. This has been seen in a number of organizations including, Strikeforce, Smackgirl, and Valkyrie.^[39]

While men are required to wear a groin protector, women are forbidden from doing so. Women must wear a top and chest protector, while men are allowed neither.

First female MMA fight in United States held on March 28, 1997 by the International Fighting Championships between Becky Levi and Betty Fagan.^[40]

Strikeforce became the first major promotion in the United States to have held a female fight as the main event on August 15, 2009. The fight between Gina Carano and Cristiane Santos, known professionally as Cris Cyborg, attracted 856,000 viewers.^[41] Santos made history with her victory over Carano as she became the first Strikeforce Women's 145 lb Champion.

Invicta Fighting Championships in early 2012 became one of the first major women's pro mma organisations.^[42][43]

Ronda Rousey became the first woman fighter signed to the UFC on November 2012, and was promoted to the division's bantamweight champion. She successfully defended her title in the first UFC women's fight against Liz Carmouche at UFC 157.

Miesha Tate and Cat Zingano fought at the Ultimate Fighter 17 Finale on April 13.^[44]

On December 11, 2013 the UFC picked up the contracts of 11 female fighters to fill up their 115-pound division. The Strawweights took part in the 20th season of The Ultimate Fighter, the season winner will be the first UFC women's strawweight champion. Some of the fighters include Felice Herrig, Claudia Gadelha, Tecia Torres, Bec Hyatt, Joanne Calderwood, and even Invicta FC's Strawweight Champion Carla Esparza and many more.^[45][46]

Carla Esparza became the first UFC strawweight champion after defeating Rose Namajunas at The Ultimate Fighter: A Champion Will Be Crowned finale.^[47]

Esparza lost her title to Joanna Jędrzejczyk at UFC 185.^[48]

There are many important moments that occurred with women's MMA. One of those moments was when Bellator added Women's tournaments, and this was important because it gave a place for top fighters in the smaller weight division to be broadcast. Another moment was when Ronda Rousey won the title because of the impact she had on many other women looking to be involved in this sport. Another very important fight was when Gina Carano fought Cris Cyborg since it was the first big women's MMA fight and the first time an MMA card was headlined by a women's fight. The implementation of Invicta FC was a very significant time period because female fighters had a place to call home and were able to fight on a consistent basis in their own weight class. One last important moment was when Primetime became the first mixed martial arts card to be broadcast on national television.^[49]

Since its inception the role of women in mixed martial arts has been a subject of debate.^[50][51][52] Some observers have treated women's competition as a spectacle and a taboo topic.^[53][54]

Mixed martial arts (MMA) fights have become increasingly popular among women. Women fighters needed to be represented and marketed with more equality for a while. The average pay for women at the time was $15,000, compared to men's $38,000 per fight, which led to a lot of women being frustrated with their pay. Paige VanZant who is an MMA fighter spoke out about wage inequality in 2019 and said she wanted more money to "keep bleeding and sacrificing for this sport".^[55] US women's soccer players took legal action over the fact that their pay is significantly lower than men's. During the UFC 241 event, the highest-paid man earned $700,000, while the highest-paid female fighter earned $30,000 according to FINCHANNEL statistics. The top female earner in 2020 was Amanda Nunes, who earned $350,000 plus $100,000 if she won the fight.^[55] Conor McGregor is thought to have gotten about $3 million for each of his most recent fights. Another male MMA fighter, Alistair Overeem has recently been paid $800,000 for each match he has. Dana White, who is the president of the UFC stated that he would never allow women to compete in his organization. Although, after observing how many viewers are watching women's fights, he has since acknowledged that female athletes are "very good."^[56] Women are requesting more money from the UFC as more viewers start to watch women's fights. Female MMA fighters' earning potential has grown as they gain popularity and recognition. Even though it has changed, the most well-liked male fighters like Conor Mcgregor continue to attract larger audiences and earn more money although it definitely won't be long until women are just as popular, and it is truly equal.^[57]
