Iszak Henig, a transgender male, joined Yale's men's swimming team after finishing last year as an All-American female swimmer.
Henig has taken hormones for eight months amid his transition, but the senior's times are "about the same as they were at the end of last season," he wrote in an op-ed piece for the New York Times on Thursday.
Henig wrote that during a meet in November among 83 swimmers, he finished in 79th place.

"I wasn’t the slowest guy in any of my events, but I’m not as successful in the sport as I was on the women’s team," Henig wrote.
The four people to finish behind Henig, according to OutKick, were a swimmer born without a left arm and three others who specialize in the breaststroke.
Several days prior, in a meet against Columbia, Henig finished in 10th out of 11 in the 200-yard freestyle and 11th out of 12 in the 100-yard free. His 400-yard freestyle relay finished in last place out of five teams, and his swim time was the slowest of all swimmers in that race.
However, Henig's goal isn't necessarily to win as a man.
"Instead, I’m trying to connect with my teammates in new ways, to cheer loudly, to focus more on the excitement of the sport," Henig wrote. "Competing and being challenged is the best part. It’s a different kind of fulfillment. And it’s pretty great to feel comfortable in the locker room every day.

"I believe that when trans athletes win, we deserve to be celebrated just as cis athletes are. We are not cheating by pursuing our true selves — we have not forsaken our legitimacy. Elite sports are always a combination of natural advantage or talent and commitment to hard work. There is so much more to a great athlete than hormones or height. I swim faster than some cis men ever will."
Lia Thomas, who transitioned from male to female, won the female NCAA Championship last March, putting more fire into the debate of transgender women in sports. She was the first transgender athlete to win a Division I national title in any sport.
