Fina, swimming’s world governing body, has banned transgender athletes from competing in women’s elite races if they have gone through any part of the process of male puberty.

The new policy requires transgender competitors to have completed their transition by the age of 12 in order to be able to compete in women’s competitions.

Fina will also aim to establish an ‘open’ category at competitions for swimmers whose gender identity is different than their birth sex.

The policy was passed with 71% of the vote from 152 Fina members.

The decision was made during an extraordinary general congress at the ongoing World Championships in Budapest.

Fina’s decision follows a move on Thursday by the UCI, cycling’s governing body, to double the period of time before a rider transitioning from male to female can compete in women’s races.
