That's the whole premise of insurance: to spread the cost among many, so no one gets wiped out. It's a pretty socialistic kind of deal, really. I [who am very healthy, with no chronic conditions, needing almost zero medical care] am helping to keep the cost 'reasonable' for those who have all kinds of lifelong medical problems: hypertension, diabetes, etc.
Men don't get pregnant [or we'd all be only children, lol], but they do have children, [and mothers!] so the pregnancy and contraceptive coverage is in their best interests as well. And AFAIK, there is no insurance that pays for an elective abortion.
