I guess it mostly depends on the attitudes and behaviours of the male students, whether they can be respectful of their female classmates, or whether, when entering a co-ed environment for the first time they turn into amoral sex-crazed lunatics.

Sweeping generalisation here, but it's usually the men who treat women in a degrading fashion and not the reverse, so it depends on whether the young men can behave with some semblance of decorum.
