Espiral la se yon kò etranje e konsa lakòz enflamasyon nan pawa a matris, ki se inofansif, sepandan, paske li pa deklannche pa viris oswa bakteri. Selil yo enflamatwa ka dirèkteman kraze espèm; an menm tan an se yon enplantasyon ki anpeche pa chanje matris la pawa. Nan yon ijans, Se poutèt sa, pafwa "espiral a apre sa" (menm jan ak "maten an apre grenn") yo itilize.

The spiral is a foreign body and thus causes inflammation in the uterine lining, which is harmless, however, because it is not triggered by viruses or bacteria. The inflammatory cells can directly break down sperm; at the same time an implantation is prevented by changing the uterine lining. In an emergency, therefore, sometimes "the spiral afterwards" (similar to the "morning after pill") is used.
