The Executive Board of the International Olympic Committee (IOC) have approved the consensus proposed by the IOC Medical Commission stating the conditions to be respected for a person who has changed sex to compete in sports competitions.
These conditions will be applied as of the Games of the XXVIII Olympiad in 2004 in Athens.
The consensus reads as follows:
Statement of the Stockholm consensus
on sex reassignment in sports
On 28 October 2003, an ad-hoc committee convened by the IOC Medical Commission met in Stockholm to discuss and issue recommendations on the participation of individuals who have undergone sex reassignment (male to female and vice versa) in sport.
The group was composed of:
Prof. Arne LJUNGQVIST (SWE)
Prof. Odile COHEN-HAGUENAUER (FRA)
Prof. Myron GENEL (USA)
Prof. Joe Leigh SIMPSON (USA)
Prof. Martin RITZEN (SWE)
Prof. Marc FELLOUS (FRA)
Dr Patrick SCHAMASCH (FRA)
The group confirms the previous recommendation that any "individuals undergoing sex reassignment of male to female before puberty should be regarded as girls and women" (female).
This also applies to individuals undergoing female to male reassignment, who should be regarded as boys and men (male).
The group recommends that individuals undergoing sex reassignment from male to female after puberty (and vice versa) be eligible for participation in female or male competitions, respectively, under the following conditions:
- Surgical anatomical changes have been completed, including external genitalia changes and gonadectomy
- Legal recognition of their assigned sex has been conferred by the appropriate official authorities
- Hormonal therapy appropriate for the assigned sex has been administered in a verifiable manner and for a sufficient length of time to minimise gender-related advantages in sport competitions.
In the opinion of the group, eligibility should begin no sooner than two years after gonadectomy.
It is understood that a confidential case-by-case evaluation will occur.
In the event that the gender of a competing athlete is questioned, the medical delegate (or equivalent) of the relevant sporting body shall have the authority to take all appropriate measures for the determination of the gender of a competitor.
