Serrano to end career in Puerto Rico in January

Serrano is the only Puerto Rican boxer, male or female, to become an undisputed world champion.

Her profile reached new heights after she became the first fighter to sign with Most Valuable Promotions (MVP) in 2021.

Founded by YouTuber-turned-boxer Jake Paul and Nakisa Bidarian, MVP has invested heavily in women's boxing in recent years.

"Nakisa, Jake and MVP believed in me and in women's boxing, and together we've helped change what's possible for women in this sport," Serrano said.

"We've fought for respect, equal opportunities, fair pay, and the choice to compete under the same rules as men.

"There's still more work to do, and I'll continue fighting for the next generation long after I hang up my gloves."
