>>40115805america has a strangely unique anti-IUD culture due to one of the very first ones going disastrously wrong and killing loads of women via infection, which caused them to not take off here like they did in europe and elsewhere during the same time period
IUDs also aren't 100% failproof; the only truly failproof method for absolute certaintly you will never get pregnant is total removal of the reproductive organs. an IUD is contraception, while a hysterectomy is actual sterilization.
