New eligibility policy introduces mandatory sex testing for all World Boxing competitions
World Boxing has introduced mandatory sex testing, to determine the eligibility of male and female athletes that want to participate in its competitions as part of a new eligibility policy published HERE today.
The policy is designed to ensure the safety of all participants and deliver a competitive level playing field for men and women and means that all athletes over the age of 18 that want to participate in a World Boxing owned or sanctioned competition will need to undergo a once-in-a-lifetime PCR (polymerase chain reaction) of functional medical equivalent genetic screening test to determine their sex at birth and their eligibility to compete.
The new policy comes into effect from 20 August 2025 and will be applied in the female category at the forthcoming World Boxing Championships in Liverpool, 4-14 September 2025.
It means that all athletes who wish to take part in the 10 female weight categories at the World Boxing Championships in Liverpool will need to undergo a PCR or functional medical equivalent genetic screening test to certify their eligibility to box.
World Boxing’s policy on ‘Sex Eligibility’ has been crafted by a Working Group of its Medical and Anti-Doping Committee which examined medical evidence from a range of sources and spent nearly 12 months consulting with experts and studying legal, societal and sporting developments relating to the issue of eligibility by sex.
Under the policy, World Boxing will operate two categories as determined by sex: a men’s category and a women’s category. To be eligible for the men’s category, a competitor must be male at birth. To be eligible for the women’s category, a competitor must be female at birth.
Participation in either category will be determined by a PCR or functional medical equivalent genetic screening test to determine sex at birth. The PCR test is a laboratory technique used to detect specific genetic material, in this case the SRY gene, which reveals the presence of the Y chromosome, that is an indicator of biological sex. The test can be conducted by nasal/mouth swab, saliva or blood.
Athletes deemed to be male at birth, as evidenced by the presence of Y chromosome genetic material (the SRY gene) or with a difference of sexual development (DSD) where male androgenization occurs, will be eligible to compete in the male category.
Athletes deemed to be female at birth, as evidenced by the presence of XX chromosomes or the absence of Y chromosome genetic material (the SRY gene) or with a DSD where male androgenization does not occur, will be eligible to compete in the female category.
National Federations will be responsible for testing and will be required to confirm the sex of their athletes when entering them into World Boxing competitions by providing a certification of their chromosomal sex, as determined by a PCR or functional medical equivalent genetic screening test.
A failure to provide certification of the chromosomal sex of an athlete or the provision of a false certification, will render the athlete ineligible to compete and may lead to sanctions against the athlete and/or its National Federation.
Where test results for boxers that want to compete in the female category reveal Y chromosome genetic material and a potential Difference of Sexual Development (DSD), the initial screenings will be referred to World Boxing’s expert medical panel for genetic screening, hormonal profiles, anatomical examination or other valuation of endocrine profiles by medical specialists. The policy includes an appeals process, and support will be offered to any boxers that provide an adverse test result.
The President of World Boxing, Boris van der Vorst, said: “World Boxing respects the dignity of all individuals and is keen to ensure it is as inclusive as possible, yet in a combat sport like boxing, we have a duty of care to deliver safety and competitiveness fairness which are the key principles that have guided the development and creation of this policy.
“It has been a long and detailed process, but it was vital that we examined all of the medical, legal and sporting issues raised by this issue and I am confident that in introducing testing to certify the eligibility of an athlete to compete as a male or female, the new policy on ‘Sex Age and Weight’ will deliver sporting integrity and protect the safety of all participants.
“We recognise that the issues relating to eligibility in boxing are more pronounced in the women’s events which is why we have made the decision to implement the policy in the female category first, where it will apply for the forthcoming World Boxing Championships and this was communicated to all of our member National Federations some time ago, to enable them to begin the process of testing.
“I would like to thank the members of the Working Group for their hard work in developing and creating this policy over the last year and am grateful for the ongoing support of our member National Federations for their commitment and assistance in implementing it.”
World Boxing’s decision to prioritise testing in the female category is based on a recognition that the issues of safety and sporting integrity in relation to eligibility are most pronounced in women’s boxing. Testing will be applied for boxers in the male category at all World Boxing competitions from 1 January 2026.
This will mean that from 1 January 2026, all athletes over the age of 18 that want to participate in a World Boxing owned or sanctioned competition will need to undergo a, once-in-a-lifetime, PCR (polymerase chain reaction) or a functional medical equivalent genetic test to determine their sex at birth and their eligibility to compete.
World Boxing was launched in April 2023 with a mission to ensure that boxing remains at the heart of the Olympic movement. It held its first formal meeting with the IOC in May 2024 and on 25 February 2025, it was granted provisional recognition by the IOC as the International Federation (IF) within the Olympic Movement governing the sport of boxing at world level.
