Whats the difference between the hormone coil and the non-hormonal coil?

Hi @Han,

The IUD (non-hormonal coil)

  • does not contain a hormone, but instead slowly releases copper, which prevents sperm from surviving in your cervix, uterus or fallopian tubes. It may also stop fertilised eggs from implanting in the womb.
  • these can last for 5 or 10 years depending on the type.

The IUS (hormonal coil)

  • works by releasing a progestogen hormone, which thickens the mucus from the cervix (opening of the womb), making it harder for sperm to move through it and reach an egg. It also causes the womb lining to become thinner and less likely to accept a fertilised egg. In some women, the IUS also stops the ovaries from releasing an egg (ovulation), but most women will continue to ovulate.
  • if you have heavy or painful periods, the IUS can make your periods lighter, shorter, and sometimes less painful.
  • these can last for 3-5 years depending on the type.

Simularities

  • both are over 99% effective.
  • you can have a coil removed at any time my a train professional. Removal of a coil is a very quick procedure (about 30 seconds). It may be a little uncomfortable but is much less uncomfortable than the fitting procedure.
  • neither coil protects against STIs so you may want to consider also using condoms.

You can read more about the hormonal coil (IUS) and the non hormonal coil (IUD)) on SH:24.

@Han, if there is anything else you’d like to know, please write back.

Or if anyone else can add something to this conversation - how you made a choice between the two coils, that would be great to hear!

Is the process of getting them fitted the same?

Does it take the same amount of time/ do you experience same levels of pain etc.?
