The intrauterine device (IUD) is an effective method of birth control.
However, IUD-induced uterine bleeding is a major side-effect and always
causes inconvenience, sometimes even anaemia. It has been reported that
oral administration of indomethacin could can reduce IUD-induced uterine
bleeding. In the present study, we investigated whether
indomethacin-releasing copper IUD (IR-Cu-IUD) can prevent insertion-
induced uterine bleeding and its mechanism. Nine healthy volunteers of
reproductive age were selected for the study. Endometrial tissues were
collected at same menstrual stage prior to and 3-6 months after IR-Cu- IUD
insertion. Endometrial morphology, cell proliferation/differentiation,
morphometry and activity of complement Factor VIII were examined. No
significant difference was found in any of the parameters examined in the
same patients, both prior to and after IR-Cu-IUD insertion. By comparison
with data previously obtained from the patients who had Cu-IUD insertions,
it is clear that IR-Cu-IUD markedly reduced IUD-induced uterine bleeding
and this reduction is primarily contributed by the anti-inflammatory action
of indomethacin.
