World Boxing said that an appeal process initiated by the Chinese Taipei Boxing Association (CTBA) on behalf of Lin, and conducted in line with its mandatory sex testing, had been completed.
The test is used to detect a specific gene which World Boxing said “reveals the presence of the Y chromosome that is an indicator of male biological sex”.
World Boxing’s policy includes an appeal process so boxers that screen positive for the SRY gene can lodge an appeal and provide supporting evidence.
The body said following an initial test in 2025, the CTBA began the appeal process and submitted a series of medical documents.
“The World Boxing Medical Committee considered and evaluated the medical documentation presented and determined that the boxer was deemed to be female and eligible to compete in the female category,” it said.
Tom Dielen, secretary general of World Boxing, added: “We recognise that this has been a difficult period for the boxer and the CTBA, and appreciate the way they have approached the appeal process and their acknowledgement of World Boxing’s requirement to ensure that its eligibility policy, which is designed to deliver safety and sporting integrity, has been correctly implemented and followed.”
The CTBA said in a statement: “This is a tremendous relief for Lin Yu-ting.
“We are pleased that World Boxing’s independent medical experts thoroughly reviewed all evidence and confirmed that she has been female since birth, meeting the requirements, with no competitive advantage, and ensuring her rightful place in the women’s category.
“We recognise World Boxing’s responsibility to uphold safety and fairness in competition, and we appreciate the professional and rigorous manner in which this matter was handled.”
Algeria’s Khelif said earlier this year she would also be willing to take World Boxing’s new sex test, if it would allow her to defend her title at the 2028 Olympic Games in Los Angeles.
The CTBA added: “Lin Yu-ting’s return marks a significant moment for both her career and the broader sporting community, reinforcing the principles of fairness, transparency and athlete welfare in international boxing.”
Lin has now been registered to take part in the upcoming Asian Boxing Championships, which take place in Mongolia from 29 March to 10 April.
