Young women has lot more options than your young men.
I can signal a man with Ferrari on the road and he will let me spend my time with him but the chances of man getting the same treatment is next to nothing.
As a woman who worked in stem, stem has very bad payoff for me.
It takes a lot of work/efforts to get anywhere if you want to do real work in stem.
It's much easier for me to give talks and become a influencer as lots of men follow me on social media.
So why should I scarifice opportunity meet powerful men in social setting through my work and spend my young/pretty years at a desk job where no one will notice me?
My grandmother told me, men value young women so don't waste your pretty years.
