I mean there's reams of women in tech or academia who talk about this shit. "I left my PhD program because I was constantly belittled and harassed by my advisor and labmates" "I left my position for a different company because I kept getting passed over for promotion after I had kids" "I switched majors from CS in college because most of my classmates were men who made me uncomfortable" "I was bullied in high school by boys because they thought I didn't get accepted into school based on merit". These are all stories I've heard and there are many of them. Go ask some women in your workplace and I'd bet money they've heard stories like this from other women they know or have experienced it themselves. I'm a man and I'm tired of hearing the contrarian denials regarding these problems from my peers in the industry. Maybe every woman I know in the industry experiencing sexism at some point in their education or career is too anecdotal for you I guess.

I'm sure there's studies in labor and education stats to show some quantitative evidence of this stuff but I'm not going to waste my time proving the obvious to you.
