The Northeast Calgary Women’s Clinic and The IUD Clinic have joined together!

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


  • 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

Still have questions? You can get in touch with us today to book an appointment.
