Transgender female athletes have a physical advantage over their biological female opponents despite taking testosterone suppressants, doctors confirmed.
A Mayo Clinic doctor, an international physiologist, and a Harvard University evolutionary biologist told the New York Times that University of Pennsylvania swimmer Lia Thomas’s performance this past season showed there “are dramatic differences in performances” between transgender females and biological females.
"There are social aspects to sport, but physiology and biology underpin it,” Dr. Michael J. Joyner of the Mayo Clinic said. “Testosterone is the 800-pound gorilla.”
