No, women are not less capable of getting a degree. Instead, the problem is often that they have such a bad time, in those programs, due to the existence of a toxic culture, that they don't want to put up with that crap, and instead leave to get a job in industry that has a less bad culture (because they have other options). Unfortunately, toxicity on all stages of the pipeline tends to drive out people who would be good engineers, but instead decide to do something else, because they have alternative options that don't suck so much, for cultural reasons.
