Caster Semenya, the South African athlete whose masculine look and testosterone levels caused a stir back in 2009, when she won an 800-meter world championship, has gotten more feminine looking over the last few years—because she has to. Due to recent rule changes by the International Association of Athletics Federations, women who want to compete must have certain testosterone levels, which do not exceed the male threshold, reports The Toronto Star's Stephanie Findlay. "If it does, she must have surgery or receive hormone therapy prescribed by an expert IAAF medical panel and submit to regular monitoring," explains Findlay. And, per Danie Cornelius, a track and field manager, Semenya is one of those athletes undergoing treatment. "I know she gets treatment. What the treatment entails, I can’t give the details," he told Findlay. As the photo above shows, with Semenya in 2009 on the left and her winning a recent race on the right, whatever the treatment entails, it has had a notable effect on Semenya's appearance.
Even though Semenya was cleared for competition after undergoing testing, when Semenya won the championship in 2009, critics claimed her masculine build gave her an unfair advantage. "These kind of people should not run with us. For me, she's not a woman. She's a man," said Elisa Cusma, who placed sixth in the race said at the time, notes Findlay. Back in 2009, The New Yorker's Ariel Levy called Semenya "breathtakingly butch" in a profile of the runner. "Her torso is like the chest plate on a suit of armor. She has a strong jawline, and a build that slides straight from her ribs to her hips," Levy wrote, which the photo to the right confirms.
