Transgender Athletes in the Olympics

Transgender man Chris Mosier qualified for the men's duathlon world championship and challenged the International Olympic Committee policy, specifically asking for the removal of the requirement for surgery.

At the IOC Consensus Meeting in November 2015, parties agreed the following guidelines to be taken into account by sports organizations when determining eligibility to compete in male and female competition:
1. Those who transition from female to male are eligible to compete in the male category without restriction.
2. Those who transition from male to female are eligible to compete in the female category under the following conditions:

2.1. The athlete has declared that her gender identity is female. The declaration cannot be changed, for sporting purposes, for a minimum of four years.
2.2. The athlete must demonstrate that her total testosterone level in serum has been below 10 nmol/L for at least 12 months prior to her first competition (with the requirement for any longer period to be based on a confidential case-by-case evaluation, considering whether or not 12 months is a sufficient length of time to minimize any advantage in women’s competition).
2.3. The athlete's total testosterone level in serum must remain below 10nmol/L throughout the period of desired eligibility to compete in the female category.
2.4. Compliance with these conditions may be monitored by testing. In the event of non-compliance, the athlete’s eligibility for female competition will be suspended for 12 months.
