We have a culture of alcohol being involved in most team interactions outside of work. Those mostly take place in the evening, a time when, usually, private socializing, including mate seeking behaviour, happens. That alone would be quite a fertile ground for sexual harassment, if you add a few females to a group mostly consisting of men. Then add companies where people work long hours and have little life outside of work. And now consider conferences, where people are away from their regular social circle for extended periods of time.

I would not want to be a young, attractive female working in this environment.
