That's fine if they don't want to compete with men, but the statements were because "it's unfair". I was curious if there had been any studies on this.
Well, (and I hesitate to say this because of HN guidelines, but) it was in the article, which I assumed you read. It was this assumption that made me think you wanted evidence that it is women who are complaining about competing against men.

> Late last year Dr. Jane Thornton, the I.O.C.’s medical and scientific director and a Canadian former Olympic rower, presented the initial findings of a review of athletes who are transgender or have differences of sexual development, known as DSD, and are competing in women’s sports. That analysis, which has not been made public, stated athletes born with male sexual markers retained physical advantages, including among those that had received treatment to reduce testosterone.
Does it have a link to any of the findings?

The findings I posted where from the linked article, to the nytimes. The findings were exactly as I posted them; in brief, athletes born with male markers retain their physical advantages.
It’s not evidence until published because it can’t be disputed.
