im not sure the athletes would want to do that.they know semenya,niyonsaba and some others might not be really female,but theyre not male,either,and the fact is,they dont have penises.im all likelihood,they were raised as girls.also im pretty sure nobody blames semenya herself.she didnt have any choice as to who,or what she is.whether or not she should be competing against women,im not sure,but she has a vagina,and shes not a man.
