Strength of trans women drops slightly after year of treatment, research claims

  • Loss of lean body mass around 5% after testosterone blockers
  • Study raises questions for sport related to safety and fairness

Men have a greater performance advantage over women in cricket, golf and tennis compared to sports such as running or swimming according to new research, which also finds that testosterone blockers taken by transgender women only minimally reduce the biological advantage underpinning performance.

The study, published in Sports Medicine, found that while elite men are around 10-13% faster than elite women at running and swimming, the gap is between 29% and 52% when it comes to bowling cricket balls, hitting long drives, weightlifting and in sports that generally rely more on muscle mass and explosive strength.
