The effects of testosterone in the womb and during puberty have extremely profound effects on the body that do not ever go away throughout your entire life. Bone density and neuromuscular efficiency are vastly different between the sexes and do not regress with the introduction of hormones later on. The level of testosterone on competition day has by comparison almost no effect on anything. National women's teams in many sports regularly compete with and LOSE to normal boys' high school teams. The lie that MtF people have no significant advantage in sports is just a lie agreed upon. You know it's a lie, so don't agree with it. It's a lie for purely political purposes.
