Opponents say trans women have advantages gained in male puberty that are not sufficiently reduced by hormone treatment. “All politics aside, all biases aside, science has to direct it,” said lead author Blair Hamilton, who researches trans athletes at Britain’s Brighton University. “I’ve played women’s sport now for four years,” said Hamilton, whose study backed testosterone limits for trans women in sport. However, concerns about physical safety led World Rugby to ban trans women from international women’s games last year. The muscular advantage enjoyed by trans women falls by about five per cent after a year of testosterone-suppressing treatment, according to their research.
