Step in the right direction but let us be real. All of these males will always have an advantage even if they limit the testosterone to say 3nmol/L for the last 3 years or something.
Why? Because their body went through male puberty. They are larger than they would otherwise be, they have different skeletons than they would otherwise have, etc. etc. etc.
To link this purely to muscle mass, strength and power as somehow indicated by one hormone (testosterone) is a complete joke. I understand that this is something measurable, i.e. something you can 'research' while the height, skeletal, lung size, etc. advantage is a counterfactual and you can not measure it, the answer is not to pretend that these don't matter. That all that matters is testosterone that you can measure.
