This one is more important for women, because in most cases, women’s bodies process alcohol less efficiently than men’s. 1 Also, women are far more likely to use artificial hormones in the form of birth control pills/patches/rings/IUDs or hormone replacement therapy. The molecular structure of these hormones is not identical to the ones produced naturally by your own body, and studies are showing that this tiny difference, especially in artificial progestin 2 versus (apparently hugely beneficial 3) natural progesterone, may cause a host of side effects 4. What to do? For those in monogamous relationships, the copper IUD contains no hormones. For those not in monogamous relationships, condoms are a great idea anyway (though note that nonoxynol-9 5 spermicide may have harmful effects).
