1) Transgender guidelines
A. Since the 2003 Stockholm Consensus on Sex Reassignment in Sports,
there has been a growing recognition of the importance of autonomy ofgender identity in society, as reflected in the laws of many jurisdictions
worldwide.
B. There are also, however, jurisdictions where autonomy of gender identity is
not recognised in law at all.
C. It is necessary to ensure insofar as possible that trans athletes are notexcluded from the opportunity to participate in sporting competition.
D. The overriding sporting objective is and remains the guarantee of faircompetition. Restrictions on participation are appropriate to the extent thatthey are necessary and proportionate to the achievement of that objective.
E. To require surgical anatomical changes as a pre-condition to participation
is not necessary to preserve fair competition and may be inconsistent withdeveloping legislation and notions of human rights.
F. Nothing in these guidelines is intended to undermine in any way therequirement to comply with the World Anti-Doping Code and the WADA
International Standards.
G. These guidelines are a living document and will be subject to review in lightof any scientific or medical developments.
In this spirit, the IOC Consensus Meeting agreed the following guidelines to betaken into account by sports organisations when determining eligibility to compete
in male and female competition:
1. Those who transition from female to male are eligible to compete in themale category without restriction.
2. Those who transition from male to female are eligible to compete in thefemale 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 minimumof four years.
2.2. The athlete must demonstrate that her total testosterone level in serumhas been below 10 nmol/L for at least 12 months prior to her firstcompetition (with the requirement for any longer period to be based ona confidential case-by-case evaluation, considering whether or not 12
months is a sufficient length of time to minimize any advantage inwomen’s competition).

2.3. The athlete's total testosterone level in serum must remain below 10
nmol/L throughout the period of desired eligibility to compete in thefemale category.
2.4. Compliance with these conditions may be monitored by testing. In theevent of non-compliance, the athlete’s eligibility for female competition
will be suspended for 12 months.

2) Hyperandrogenism in female athletes
In response to the interim award dated 24 July 2015 in Chand v AFI and IAAF
CAS 2014/A/3759, the IOC Consensus Meeting recommended:

Rules should be in place for the protection of women in sport and thepromotion of the principles of fair competition.
The IAAF, with support from other International Federations, National
Olympic Committees and other sports organisations, is encouraged torevert to CAS with arguments and evidence to support the reinstatement of
its hyperandrogenism rules.
To avoid discrimination, if not eligible for female competition the athlete
should be eligible to compete in male competition.
