Birth control pills prevent pregnancy, a possible consequence of sex for women. Yet many insurance plans don't cover contraceptives. It's as if contraceptives are a medical frill. They are not. Contraceptives, which prevent pregnancy and some sexually transmitted diseases, should be considered basic health care.
Pregnancy is a medical condition, just as impotence is a medical condition.
But the cost benefit of preventing pregnancy is much greater than the cost of treating impotence. Even when taking Viagra out of the equation, it's clear from an insurance cost standpoint that covering contraceptives makes sense. It's also the right thing to do. Moreover, contraceptives by definition prevent unintended pregnancies. And that means fewer abortions.
