It's the other way around, which is the reason this forced diversity is so controversial.
STEM fields still don't attract enough women, because they largely don't want to work in that field. This is despite expensive recruitment campaigns in multiple Western countries, plus thousands of pounds in bribes and grants to coerce them into the subject. There's no similar push to get men into occupations where they're under represented. In the Nordic countries, where a lot of this originated, they have less female candidates in STEM fields than in the UK and US.
