World Athletics bans trans females who experienced male puberty

Transgender women who have experienced male puberty will not be permitted to compete in female world ranking competitions, the World Athletics announced Thursday.

The international council opted to ban the swath of prospective athletes instead of continuing to follow its previous rules that placed parameters on the testosterone levels of transgender female athletes.

Previously, transgender women were required to reduce their amount of blood testosterone to a maximum of 2.5 nanomoles for a period of 24 months to qualify for competition.
