Comparison Between Two Types of Copper Bearing Intrauterine Device Cu375 and Cu380Ag Regarding Bleeding Pattern Randomized Controlled Trial

Abstract

C opper intrauterine devices are valuable birth control resources. Because of the duration of high impact in contraception, low failure rate, reversibility and low cost, copper IUD is used by over 130 million women around the world. There are two types of commonly used IUDs including the Multi Load CU 375 IUD and Copper T 380A IUD. The former was originally approved by the U.S. FDA in 1984, and the latter invented by the Dutch in 1974. Several multi-center randomized controlled trials (RCTs) have been performed to compare the effectiveness and safety of TCu380A and MLCu375. Both MLCu375 and TCu380A are generally acknowledged as safe and effective, and are strongly recommended by the WHO on that basis.
