Amanda Serrano gave her verdict on three-minute rounds after defeating Danila Ramos.
Serrano remains world champion after a successful title defence on Friday night, and many will expect her to go on to challenge for more belts in the coming years.
Should could move on to a rematch with Katie Taylor, after the Irish fighter takes on Chantelle Cameron in her own attempt to run it back to avenge defeat.
Serrano and Ramos made history after fighting for a title with 12 three-minute rounds for the first time for women in more than a decade.
Speaking to ESPN after the fight, she claimed to have found the experience much the same as the traditional two-minute format.
"In the sixth round, I was like, is it really three minutes or did they go back to two minutes?" she said after retaining her three featherweight straps.
"I felt good. I was in really good shape. I trained really hard for this fight knowing I had to go out there and prove to everybody that women can do whatever they put their minds to."
"This was a historic night," she continued. "I hope it's just the beginning, because I know there are a lot of women coming after me. I know the future is bright for us".
