IUD Questions

IUD’s vs Birth Control Pills

How are hormonal IUDs different to birth control pills (or the patch / vaginal ring)?

Birth control pills (or the patch, or vaginal ring) typically:

  • contain TWO hormones: estrogen and progesterone
  • the hormones have to go through your whole system to work
  • they “shut down” your ovaries and stop you from making an egg

IUDs:

  • contain NO hormones or ONE hormone only
  • work locally inside your uterus
  • do not disrupt your own hormonal cycles
  • your ovaries still function and majority of women still ovulate or make an egg as usual
