"The twist here is that female contraceptives prevent unintended pregnancies in the person actually taking the contraceptive. Since a pregnancy can cause some women significant health problems, the risk of contraceptive side effects can be offset by the benefit of avoiding an unintended pregnancy. However, men do not directly experience any of the health risks of pregnancy — their female partners do. Thus it becomes more difficult, ethically, to justify the side effects of hormonal contraceptives in men."
I find it interesting that mainstream science does not think this way about vaccines.
Rubella, for example is an extremely mild disease in childhood - but can have serious consequences for a fetus. So why is it ethical for eveyone to assume the risks of vaccinating for a typically benign disease? Teenage girls should be offered a rubella vaccine if they have not had rubella.
Similar arguements can be made for Hep. B, mumps, and HPV.
