Yes, but at such (often but not always religious) schools the policy is nearly already gender-symmetric (except AFAIK schools don't tend to bother to prohibit same sex overnight guests).
Also, the policies are rarely enforced, and frequently have more to do with building security (guests must be registered, etc.) than anything else.
And frankly, I don't understand why we allow college dorms housing what are legally adults, to make any requirements a landlord wouldn't be able to make. Especially when schools have residency requirements or off-campus housing isn't a realistic option.
