This is what I found on Wikipedia, so YMMV:
"The presence of a device in the uterus prompts the release of leukocytes and prostaglandins by the endometrium. These substances are hostile to both sperm and eggs; the presence of copper increases this spermicidal effect.[40][41] The current medical consensus is that spermicidal and ovicidal mechanisms are the only way in which IUDs work.[35]"
