Current state of intrauterine contraceptive devices

Background: Intrauterine contraceptive device (IUCD) is the most commonly used method of contraception in many countries. Despite the availability of many generations of IUDs with variable shapes and configurations, side effects and complications are frequent. We hypothesize that a modified IUD design with a fundal seeking effect will nullify the side effects and the complications of the currently available IUDs. Such a design will be at least as effective as the traditional copper devices without their well-known disadvantages. This simple modification of the IUD shape will add to the acceptability of this method even in communities with known preferences to other alternatives.
