The UCI has announced that it could introduce new guidelines for the eligibility of transgender female athletes competing in cycling events beginning in 2020. The guidelines could stipulate a maximum testosterone threshold of 5 nanomoles per litre (nmol/L), which is half of the current maximum threshold of 10 nmol/L, for transgender females to be eligible to compete in the women's category. The new regulations will be discussed internally and are pending approval from UCI Management Committee.

The decision was reached following the recent International Meeting on Transgender Eligibility in Competitive Sports in Lausanne, Switzerland, on October 19.
