Thomas started swimming at age 5, eventually competing for three seasons on the men’s swimming team at Penn, The Post reported earlier this month. Toward the end of those three years, in the spring of 2019, she started going through testosterone suppression treatment, which the NCAA then required transgender women to undergo for a full year before competing in women’s sports, according to The Post. She continued to swim for the men’s team in the fall of 2019, when she would have been ineligible to compete against women.
