The governing body for international swimming approved new policies for transgender swimmers that will go into effect starting on June 20.
In a notice (pdf) on June 19, the International Swimming Federation (FINA) said it will only allow biological male swimmers to compete in women’s events if they have not experienced male puberty and have had puberty suppressed before age 12. They would also have to “continuously [maintain] their testosterone levels in serum (or plasma) below 2.5 nmol/L.”
