Why do churches in the West have twice as many women in attendance as men?

Every other major religion is roughly 50/50 in their unisex worship services. and outside the West most churches are likewise about 50/50. But Western churches are about 65-35 women to men.

Why are there so few men in Western congregations? What can be done to change this?
