However, World Rugby has issued a robust defence of the research on which its recommendations are based, as well as its application of that research, which has concluded there is a minimum of 20% to 30% increase in injury risk factors when typical male-bodied and female-bodied players are involved in tackles – even when trans women suppress their testosterone in line with International Olympic Committee rules.
“From the outset, we have sought to balance inclusion, safety and fairness within the context of a physical sport based on strength, power, speed and contact,” World Rugby said in a statement. “However, the scientific medical evidence position regarding the impact of testosterone suppression for trans women athletes is compelling, the injury risk at the elite level is real, and should be tackled.
“While welcoming all contributions, it is simply false to state that the research is not peer-reviewed and insufficient to warrant the approach as evidenced by the numerous published studies, which consider biological advantages of males over females and the slight reduction of advantages when testosterone is suppressed.
“World Rugby has operated a fully inclusive and extensive transgender guideline consultation process with relevant bodies as evidenced by the ground-breaking workshop in London. Every element was considered and input from trans advocacy groups was sought, and valued for all the reasons raised by the academics.”
