If I'm reading Harvard's conclusions correctly, it seems like the next step would be gender neutral dorms--byroom....
However, I will note that I did live in a dorm in Germany as a PSU exchange student where the bathrooms were co-ed. In the late 70s. But the stalls were floor to ceiling (tho the urinals were not enclosed) and there was a separate lockable single room for a shower. Most of the rooms were singles--only one double room on each floor (and I knew a married couple that had the one on my floor). You got used to it--and the dorm was mostly male anyway at the time.
