Teenage mental health aside (probably not caused by lack of desirable marriage partners), loneliness and desperation, and the drug abuse and suicide that follows, seem to be primarily male problems.
Maybe enough women don't want to get married, or they have another way of dealing with that not happening, but I'm not sure there's a crisis there. Granted, I don't follow surveys closely, but generally if women are affected, it will be a widely known story and the news will pick it up. It's not, so I assume they aren't.
