As a victim of it, I disagree. Since women have the unique burden of getting pregnant, these clauses are discriminatory against us merely on the basis of our biological status. I'm not planning on getting pregnant, but I am a straight sexually active woman (like most of us), so it could happen. My husband doesn't have to pay more for insurance for this, but I do. Somehow I doubt that if men had anything as medically unique that anybody would ever consider excluding it from a plan. Also, those states that don't allow the maternity exclusion have marginally higher insurance rates than states that allow it. However, if you add maternity on to your coverage in a state that allows the maternity exclusion, you wind up paying significantly more.
