Oh, wow, do you come off as uninformed! Birth control for women has tons and tons of side effects, and it's in no way easier to prevent successful ovulation than it is to prevent fertile sperm production. In fact, birth control drugs for men have been repeatedly blocked by regulators for having too many side effects, while those side effects pretty closely mirror those of the pill for women. So, interfering with everything from blood pressure to appetite is acceptable when women are affected, but can't be burdened upon men?
Interrupting the ovulation cycle comes at great cost for the body. All the “non-hormonal” ways of birth control we have (except the condom) require either poisonous metals and foreign objects to be pushed inside the uterus, increasing the risk for cysts, causing pain, and regular checkups and painful procedures to be applied or fitted (diaphragm). Or toxins to be applied straight into a woman's private parts (spermicides). Calendar-based methods and “pulling out” have large margins of error, as have condoms.
Yep.
Firstly: Disregarding the discomfort of having to see the doctor and having something shoved inside your body is a weird mistake, especially men tend to make regularly when talking about those things. Having your genitals exposed to and then painfully tampered with by what is ultimately a stranger isn't a thing most people would describe as a pleasant afternoon activity.
The side effects aren't just from hormones. Imagine having to do a prostate exam every 6 months and a metal plug shoved close to your prostate through your urethra every few years (not the same, of course, just an attempt at an analogy, since men are one hole short down there). Wouldn't you dislike that? Many women are really sensitive around their cervix and implanting the IUD can therefore be really painful.
Secondly: Period cramps increase in severity, bleeding increases for most people, and there are hints that those IUDs can increase the risk for cysts, which in turn cause issues, pain and sometimes need surgical removal.
