Excluded hormonal contraceptives, there are non hormonal means of contraception. Among them, copper intrauterine devices (IUD) are very efficient. Copper IUD are the most used contraceptives in France and in the world, even then "false ideas", like contraindication to non steroidal anti-inflammatory drugs or higher risk of tubal infertility, have tarnished its reputation. The other non hormonal contraceptives, less effectiveness, include first, the male and female condoms which are the only efficient means to prevent sexually transmitted infections and then the "local" contraceptives like spermicides, diaphragms and cervical caps. The effectiveness of these methods depends primarily on their correct use (which requires a careful training). Then these "local" means are acceptable contraceptive methods only for specific use or for very motivated women.
