Hormone-based contraception feels like something from the middle ages. It has serious side effects, it has "harmless" side effects that aren't even related to the pill anymore after years of intake, but still an annoyance (migraine, headaches, yeast infections, high blood pressure, ...)
Non-hormonal contraception has its own negative aspects:
- Copper IUDs can cause a lot of pain, inserting them isn't that easy, they are ethically troublesome (eggs can be fertilized after ovulation, but the copper IUD prevents nidation)
- Natural family planning methods are way safer than many people believe (the sympto-thermal method), but don't allow unprotected sex during fertile days
- Condoms are way safer than many people believe as well (as long as you use the correct size) and won't go away because of STDs, but are a bit annoying in relationships
And there really aren't any other alternatives right now. The state of contraception in 2017 is incredibly sad and RISUG is the first attempt, which truly can disrupt (and I don't use this word lightly) the entire industry.
It will require some social shift. Men must be willing to take responsibility for contraception, but it's already happening: Recently, the pill for men was stopped because of side effects, but the men were disappointed. They WANT to have alternatives to condoms.
