Two Nambian Sprinters ruled ineligible for Olympics for “naturally high testosterone levels”

Two Nambian sprinters Christine Mboma and Beatrice Masilingi have been ruled ineligible for the Tokyo Olympics over having “naturally high testosterone levels” according to the the Namibia National Olympic Committee and Commonwealth Games Association (NNOC-CGA).

Per CNN:

The global governing body requires that female athletes’ blood testosterone levels be under 5 nmol/L (nanomoles per liter) to compete in select women’s events, including the 400m.

The two 18-year-old athletes were ruled ineligible because of World Athletics’ policy on Athletes with Differences of Sex Development (DSD).

World Athletics banned athletes who have elevated blood testosterone levels from competing in women’s races from 400m to one mile in distance in international competition when it introduced new DSD regulations in 2018.

In order to compete, those athletes must lower their testosterone levels with medication, which World Athletics says ensures fair competition.
