But not all researchers have interpreted the existing studies in the same way, or agree that trans women have unfair advantages. Human Rights researcher Jack Byrne said studies about testosterone were red herrings because the majority of trans women reduced their testosterone to very low levels. The Otago University research was welcomed by the Olympic Weightlifting New Zealand's high performance director Simon Kent. Those rules allow trans women to compete in the women's division if their testosterone is below 10nmol/L. She said even with trans women taking estrogen, it would not lower the testosterone levels to the equivalent of a cis-female.
