The clinical performance of the Copper T 380A (TCu 380A) and the Copper T 200 (TCu 200) intrauterine devices (IUDs) was evaluated for 12 months in a group of women who had one of the two IUDs inserted. Results are from a multicenter randomized clinical trial at one site in each of six developing countries. The pregnancy rate with the TCu 380A IUD was significantly lower than the pregnancy rate with the TCu 200 IUD at 12 months (0.5 and 2.6 per 100 women, respectively, p < 0.01). No statistically significant differences between the two study IUDs were found with regards to expulsion or removals due to bleeding/pain, personal, medical, or planned pregnancy. The TCu 380A IUD did not have a disproportionately higher incidence of side effects such as intermenstrual bleeding or pain, inflammations or infections, or insertion-related events compared to the TCu 200 IUD. TCu 380A IUD users, however, were significantly more likely to report increased dysmenorrhea than were TCu 200 IUD users. The performance of the TCu 380A IUD in preventing pregnancy during this trial indicates that this IUD may be a better option than the TCu 200 IUD for women wishing to practice effective, long-term, reversible birth control without having to resort to hormonal methods.
