Patient's question:
NoDoctor's answer:
The contraceptive principle of the intrauterine device (IUD) mainly achieves its purpose by inducing sterile intrauterine inflammation and other effects. The advantages of this method include long-term safety and effectiveness; once inserted, it can be used continuously for more than 5 years. It is highly reversible, as fertility can be restored immediately after the IUD is removed. Additionally, it has no impact on sexual activity or breastfeeding.
