LOS ANGELES - Oscar De La Hoya stopped battling himself Tuesday, deciding after much internal turmoil to retire and end a career in which he won 10 world titles in six divisions and became boxing’s most popular fighter.

He made his announcement at an outdoor plaza across the street from Staples Center, where a 7-foot bronze statue of the 36-year-old Golden Boy stands.

“I’ve come to the conclusion that it’s over,” the East Los Angeles native said before hundreds of fans, including comedian George Lopez and Oscar-nominated actor and former fighter Mickey Rourke. “It’s over inside the ring for me.”

De La Hoya retired four months after he was thoroughly beaten by Manny Pacquiao, his fourth loss in his last seven fights. He has not defeated a formidable opponent since Fernando Vargas in 2002. Age and diminished skills led to losses in recent years to Felix Trinidad, Shane Mosley, Bernard Hopkins and Floyd Mayweather Jr.

He won his last title in May 2006, beating Ricardo Mayorga in six rounds for the WBC 154-pound belt. He finished with a record of 39-6 and 30 knockouts.

“This is the love of my life, boxing is my passion, boxing is what I was born to do,” De La Hoya said. “When I can’t do it anymore, when I can’t compete at the highest level, it’s not fair. It’s not fair to me, it’s not fair to the fans, it’s not fair to nobody.”

De La Hoya transcended his sport, generating crossover appeal among Latinos and whites. He was especially popular among women, who filled his news conferences and fights while screaming their approval of the boxer blessed with a magnetic smile and movie-star looks.

Unlike many fighters, De La Hoya walks away with his mind and his face intact. But he wavered often in making a final decision, and he credited his wife Millie Corretjer and business partner Richard Schaefer in helping him “realize what life is all about.”

“Even this morning, I said, ‘Are you sure?’ and he said, ‘Yes, I am ready,”’ said Corretjer, a Puerto Rican singer. “I knew after that fight in December, but it took him four more months to make his decision.”

De La Hoya said he didn’t want to let down his fans or himself.

“Now I understand why athletes have such a tough time retiring from something that you feel so passionate about, from your sport that you’re always thinking you can try one more time,” he said.

“I can still train hard and I can still compete, but when you’re an athlete that has competed on the highest level for a lot of years, it’s not fair. It’s not fair to step inside the ring and not give my best.”

Although the second half of his career wasn’t as successful, De La Hoya was a champ at the ticket window. His bouts were guaranteed pay-per-view successes, and he was a cash cow for HBO, which broadcast 32 of his fights — most of any boxer — and generated millions in profits for the cable network.

De La Hoya’s last title bout was in May 2007, when he lost to Mayweather for the WBC 154-pound title in Las Vegas, the site of most of his bouts.

De La Hoya kept a serious expression during his announcement, his voice breaking only when he thanked his father, Joel, who sat on the stage with the boxer’s wife.

“I remember the times when he would take me to the gym and never gave up on me,” De La Hoya said. “We’ve lived some tough moments inside the ring, we’ve been through everything, but my father was always there for me. Thank you for pushing me as hard as you can.”
