Intrauterine devices (IUDs) trigger endometrial inflammation and tissue changes. Progesterone-releasing IUDs, particularly those with levonorgestrel, rapidly suppress the uterine lining.

Area of Science:

  • Reproductive Medicine
  • Gynecology
  • Pathology

Background:

  • Intrauterine devices (IUDs) are widely used contraceptives.
  • Their presence in the uterine cavity elicits a local inflammatory response in the endometrium.
  • Different types of IUDs induce varying degrees of endometrial reaction.

Purpose of the Study:

  • To investigate the endometrial histological changes induced by different types of intrauterine devices.
  • To compare the inflammatory and suppressive effects of inert, copper, and progesterone-releasing IUDs.
  • To characterize the timeline of endometrial suppression with levonorgestrel-releasing IUDs.

Main Methods:

  • Histological examination of endometrial biopsies from IUD users.
  • Microscopic analysis of inflammatory cell infiltration (polymorphonuclear leucocytes, macrophages).

  • Assessment of epithelial changes, vascular alterations, and stromal reactions.

    • Main Results:

    • All IUDs induced foreign body reactions with inflammatory cell infiltration.
    • Copper IUDs showed greater leucocyte migration than inert IUDs.
    • Progesterone-releasing IUDs, especially levonorgestrel-releasing ones, caused rapid and profound endometrial suppression, including epithelial thinning and decidual reaction.

    Conclusions:

    • Intrauterine devices induce significant endometrial alterations, varying by type.
    • Progesterone-releasing IUDs offer rapid and widespread endometrial suppression, contributing to their contraceptive efficacy.
    • Understanding these mechanisms is crucial for optimizing IUD use and managing side effects.
