I would love to see what "evidence" this was based on and what this individual is saying after the Karolinska Institute article came out.
Joanna Harper's study, presumably.
Here's the same Eric Vilain talking about NCAA rules, at least he's honest:

How do the governing bodies handle this conundrum? In 2015 I interviewed Dr. Eric Vilain, a professor of human genetics at UCLA. Vilain helped write the NCAA’s rule for transgender participation. Under those rules, transgender women must undergo one year of testosterone suppression therapy before being allowed to compete. Vilain referenced studies that showed that a year of testosterone suppression significantly dropped the muscle mass in adult males.
Vilain told me that the NCAA’s rules were also aimed at inclusivity and that the governing body aims to give everyone the chance to compete. Creating rules around transgender participation, he admitted, was extremely challenging. He said that the entire concept of anatomical equality for transgender athletes was simply not feasible, and thus, it was not a stated goal of the NCAA’s rules.
“It is not about making everybody biologically equal, and I think that is a common misconception when we start talking about transgender athletes,” he said. “People want transgender [females] to be physiologically identical to [born] females, and if they’re not, it’s unfair. That is not possible.”
Dr. Vilain referenced the structure of the pelvis and the mass of certain muscle groups as anatomical differences between the male and female body that will always be somewhat different. But achieving total equality is not the point, Dr. Vilain said. The purpose of the NCAA’s rules is to, in a sense, shift the transgender female athlete’s muscle mass and physiology away from that of the average male. The goal is to create a pathway to include the transgender athlete, not create total equality.
“Can you turn a man’s body into a woman’s body? The short answer is ‘no,” Vilain said. “I think we need to move past that idea completely.”
He talks about "shifting the transgender female athlete’s muscle mass and physiology away from that of the average male". Like I said, the idea is to create 'non-men' who can be lumped in with women.
