Adams won on her professional debut on Saturday but was frustrated to fight over four two-minute rounds.
"Every time I felt I was getting close to a stoppage the bell would go for the end of the round," said Adams, 34.
On Tuesday, WBC president Mauricio Sulaiman said the organisation "will never allow three-minute rounds".
Sulaiman said some boxing jurisdictions had taken "steps backwards" in allowing longer rounds in the women's sport. He said the organisation would "limit the dehydration and the fatigue elements to lower as much as possible the risk of a tragedy".
Flyweight Adams' next bout in Leeds on 13 May is on the undercard of Josh Warrington's WBC International featherweight title fight with Kiko Martinez.
As Adams' fight is not for a WBC title, the British Boxing Board of Control (BBBofC) have allowed for the extension of the bout to four three-minute rounds.
Ireland's London 2012 Olympic champion Katie Taylor has also called for the move and Adams' management believe it will be the first time a women's bout has featured the same length of rounds as their male counterparts in the UK.
"Female boxing has come a long way since Jane Couch MBE made the sport possible here in the UK in 1998," said Adams.
"However, there is still a way to go until both male and female boxers can campaign under the same competition rules."
Adams is now intent on winning the right for women to wear lighter gloves.
The BBBofC's rules specify women must use 10oz gloves, a factor Adams' management believe is even more limiting than round length as gloves become heavier with perspiration as a fight progresses.
"It's great that the BBBofC has supported this first change and hopefully changes to glove sizes will come next," said Adams.
In the men's game, fighters competing from flyweight to welterweight are allowed to wear 8oz gloves.
BBC Radio 5 live boxing pundit Steve Bunce said a move to 8oz gloves would allow Adams to show her power, adding the current 10oz rule was "not good for business".

Sox was discovered under a car in the city's Kirkton area in March making unusual noises and suffering from hypothermia.
Her owner took Sox to the vet but the cat died the following day.
A post-mortem examination by the animal welfare charity revealed that the three-year-old cat had been poisoned.
Scottish SPCA inspector Robert Baldie said the charity was aware of a number of potential cat poisonings in the area over the past few months.
He said: "The owner in this circumstance reacted in the right way by taking Sox directly to the vet.
"Unfortunately, Sox had already suffered significantly and was in a coma with hypothermia before she then sadly passed away.
"We had suspected poisoning was the cause of Sox' condition and now the results of the post-mortem confirm it was antifreeze.
"It is essential that everyone stores antifreeze out of reach of cats and other animals as it can have devastating effects, as can be seen by the sad outcome of this incident."

The 18-year-old from Birmingham was detained after arriving back in the UK on Saturday morning.
It follows the arrest of a 24-year-old man and 20-year-old woman, both from Birmingham, on 4 April, who are on bail, West Midlands police said.
It is not in connected with five terror arrests on Friday linked to attacks in Europe, the force confirmed.
Double Olympic champion Nicola Adams will contest three-minute rounds in her next fight, a contrast to the standard two minutes in women's boxing.
