Mikaela Mayer has spoken about the "sacrifice" that female athletes make with having a family - and why pursuing a career instead should not be viewed negatively.
The undefeated WBO super-featherweight champion from America puts her belt on the line against Erica Farias on Sunday morning from 3am, live on Sky Sports, on Naoya Inoue's undercard.
She explained her view on what "society" tells females to do: "It is weird to think I'm making a sacrifice.
"It's a fair question because there is a biological clock.
"Society says we must find a mate, get married, have kids.
"There is an assumption that not having kids or being married is a sacrifice.
My point is i’ve sacrificed a lot but having kids and a husband in my 20’s ain’t it! Normalize that.— Mikaela Mayer (@MikaelaMayer1) June 14, 2021
"I just think it's funny to call it a sacrifice to pursue your dreams and a career in your 20s.
"It's way too premature - in your 20s you are still a kid, still figuring out the world. You need to enjoy your life.
"This is just my personal take on it.
"Some people think I am sacrificing having a boyfriend, husband, kids. I think that having kids in your 20s is sacrificing.
"You can do both. But it's extremely hard because you can't be as selfish. To me, that is sacrifice.
"I love my life, it's awesome, I have fun, I have a career, I travel the world. I'm not missing out on anything."
Women are currently only permitted to box two-minute rounds for a maximum of 10 rounds.
Her promoter Bob Arum said: "The third minute of a round is probably the most exciting.
"Women are deprived of that because they are just getting warmed up at the end of the second minute.
"We have to lobby the commissions to allow women to fight three-minute rounds."
Mayer noted that the gender pay gap is also an issue: "Why am I going to fight more while I receive the same treatment?
"We need to hear that promoters and networks want three-minute rounds because they see the benefit.
"If that grows women's boxing, we'll do it."
Is Terri Harper in her sights?
Mayer's rival champions in the same division are Terri Harper (WBC), Hyun Mi Choi (WBA) and Maiva Hamadouche (IBF).
Harper recently withdrew from a unification fight with Choi due to an injured hand.
"That wasn't as easy a fight as everybody thought," Mayer told Sky Sports. "It would have been a close fight.
"Choi isn't technically sound but does let her hands go. There would be a lot of punches exchanged.
"Terri is a little stronger and could land the right shots but they would really go at it in a close, exciting fight."
Former US Olympian Mayer believes Harper is trying to gain valuable experience before they meet in the ring.
"That's what she has been doing since she became champion," Mayer said.
"[Promoter Eddie Hearn] knows Terri isn't as experienced as a world champion should be.
"Before throwing her in with the cream of the crop, she needs more rounds. She is still young. It's the right move, a smart idea.
"I'm not holding my breath. It's clear they will wait for Terri to heal up then give her Choi.
"I won't sit around and wait, I will stay active."
Mayer expects a different world title unification fight later this year: "I was told Maiva Hamadouche wanted to fight. She said she was available for June 19 but then started training for the Olympic qualifiers!
"We wanted that fight. I still believe it will happen but, first, I've got to get through Farias.
"Farias is a former world champion who has fought Delfine Persoon, Cecilia Braekhus and Jessica McCaskill twice."
