Watch the moment Bev Turner locked horns with her guest over the NHS puberty blocker trial in a fiery clash live on air.
Furious parents of children who identify as trans, as well as a psychotherapist and 28-year-old detransitioner Kiera Bell have launched a legal case against the controversial trial.
Recruitment for the £10.9million puberty blocker trial commences in just weeks.
Back in December, activists, backed by the likes of gender critic and author JK Rowling, delivered a letter to the trial researchers, as well as regulatory bodies and the Government, urging them to stop the NHS trial into puberty blockers for children.
But, now, anti-puberty blocker campaigners have now launched a High Court legal challenge to stop the trial.
Those running the controversial trial on adolescents as young as 10 declared they wanted to recruit around 226 youths up to the age of almost 16.
The researchers' bid to recruit the gaggle of teens could be paused while the legal proceedings are held.
Sitting down to debate the issue, Matthew Hulbert, a former Liberal Democrat councillor, insisted that the trial should be allowed to go ahead because the Cass Review has given it the green light.

He said: "Indeed, Doctor Cass herself has said that she's really pleased that the trials are going ahead. So that's point one.
"Point two is this: so I knew I first knew that I was gay when I was about 12 years old. I wouldn't have known what to have called it then, but I knew who I liked. And I knew who I didn't.
"Are we really saying that children of the same age can't also know, in their minds and in their hearts, that they've been born into the wrong body?"
But his claim ignited a fierce incredulity within Bev, who responded: "We definitely can say that!
LATEST DEVELOPMENTS:
The trial could enrol 226 young people between the ages of 10 and nearly 16 who are questioning their gender identity | GETTY"We definitely can because there will be so many, perhaps confused kids who might think I might be gay and they would have just grown up to be gay, and that's okay.
"Once you give children, who are very suggestive, the idea that perhaps there's something wrong with them...
"And that's what we're actually saying, is being gay. You can't just be gay. There's something wrong with you. You're not in the right body.
"That child cannot consent to that. It's just nonsense."
The GB News host added: "It's too much of a risk to sterilise, but to sterilise a child, to put them on these puberty blockers, which will change the potential, not only their sexual pleasure for the rest of their life, potentially, but also their fertility.
"They can't decide that at that age."
The claimants are suing the Health Research Authority, which oversees research ethics across England, as well as Health Secretary Wes Streeting, who holds accountability for medicines regulation.
They say the trial's approval, back in November, was granted unlawfully and should be overturned.
