World Athletics has announced that starting September 1st, female competitors in elite athletics must undergo a one-time SRY gene test to determine their eligibility to compete as women. The test, conducted through a cheek swab or blood sample, will reveal the presence of the Y chromosome. This decision aims to establish clear standards for eligibility and will impact the upcoming World Athletics Championships in Tokyo from September 13-21. President Sebastian Coe emphasized the importance of ensuring a level playing field for female athletes, particularly in light of debates surrounding transgender athletes and those with differences of sex development.
