Both now require all athletes intending to compete in women’s events to undergo a genetic test. The intent is to exclude some women, including those with certain congenital “differences of sex development”, from women’s sport. This revives an old model – last widely used in 1990s – which was deemed unscientific, unethical, and ultimately unworkable. In today’s legal landscape, this renewed approach faces even more pitfalls.
