Farag, the top seed, came from behind to beat arch-rival Mohamed ElShorbagy at the University of Chicago's Cathderal Hall.

After dropping the first game, he recovered to win 7-11, 12-10, 11-9, 11-4 to claim his second world title.

Remarkably, Farag fell 7-0 down in the second game as the second-seeded ElShorbagy looked to streak away.

He masterminded a superb change of momentum, however, to back up his 2018-2019 world title win which also came in Chicago.

"I'm quite emotional about this because it's a special week for me with my baby daughter born just before this and having my parents in my corner," said Farag.

"Mohamed, when I share a court with him, every time it's an honour. 

"We are here, our generation, because of him."

Farag is married to fellow Egyptian player Nour El Tayeb, who retired aged 27 when announcing her first pregnancy.

"There are countless words I want to say about Nour," he said.

"Whatever she's going through, holding the baby for me to be able to play on this court and I'm forever grateful about that."

Despite his defeat, ElShorbagy will still take over as world number one from Farag on account of reaching the final.

"He's such a champ and he's one that really inspires me to be better every day," said ElShorbagy, who won the world title in 2017.

"He makes me want to wake up every single day to get better."

El Sherbini won her third women's title in a row and her fifth in six editions by beating Nouran Gohar.

The top seed came through against the second seed 11-5, 11-8, 8-11, 11-9 to continue her domination of the sport.

She is the third woman to win five world titles after Malaysia's Nicol David and Australia's Sarah Fitz-Gerald.

"I'm really thrilled, if anyone told me before that I was going to win five World Championships then I wouldn't believe them," El Sherbini said. 

"It's really hard to believe that I have just won my fifth World Championship.

"It was very tough until the end, Nouran kept pushing me, she keeps fighting and never gave up."

El Sherbini had not lost a game at the tournament before Gohar claimed the third to end the world number one's confident start.

The fourth game was tight but it was El Sherbini who kept her nerve to get over the line.

"I think it's the hardest part to talk when you have lost a final," Gohar said.

"I can't really complain, I have had a great week here in Chicago." 

The tournament cemented Egypt's status as the undisputed powerhouse of world squash.

France's Grégory Gaultier is the last men's or women's world champion not to come from the country, with his success coming back in 2015.
