I’m sick to death of these claims that hormone washes in the womb determine one’s sexuality or determine if one will conform to sex role stereotypes. It is no different to the old homophobic and misogynistic claims that lesbians and gay men have too many opposite sex hormones or not enough same sex hormones, and anyone who does not conform to sex role stereotypes must have too many hormones of the opposite sex. They are regressive and do not prove what the researchers claim they do.
Way back in the 1920’s they tried to claim that taking cross-sex hormones made people attracted to the same sex, they used rat experiments to try to prove it. When they tried the same experiments on gay men by giving them testosterone it just made them engage in more gay sex not seek out female partners.
The hormonal wash nonsense is just a continuation of that same old pseudo science and is used to push a narrative. All of these kinds of ‘experiments’ start from the assumption that homosexuality and non conformity to sex role stereotypes is a sign of someone being somehow like the opposite sex in a biological way. I think that premise needs to be named as the nonsense that it is. The only good thing is it shows just how regressive trans ideology is as it relies heavily on these decades old homophobic and misogynistic assumptions.
