Hi Steve! Yes that is very true, and I belive this extends to gymnastics too! Also most woman have "some kind" of testosterone level as men have female hormones like eostragon, which is perfectly normal. When my own hormone levels were tested, I too have a Testosterone spike when I get my monthly, but not as high as Caster, I presume. I wish her well, and if her whole family is saying she is a girl then that is good enough for me! :-)) hugzzzz from Vix
