    Abstract:
    Researchers followed 100 multiparous women who requested an IUD at the family planning clinic at El-Hussin University Hospital in Egypt 1, 3, 6, and 12 months after insertion of either the TCu-380 A or the TCu-200 B. They enrolled these women between September 1986-September 1987. The TCu-380 A had a higher continuation rate (89.7%) than the TCu-200 B (81.9%), but the difference was not significant (p=0.1). The continuation rate for TCu-380 A was higher than that of other studies (range 51.7-69.7%). The high continuation rate for TCu-380 A may have been due to careful selection of IUD candidates. For example, only multiparous women who had not had a pelvic infection after the last pregnancy and whose gynecological exam found no abnormalities were included. No one requested removal of the TCu-380 A because of bleeding and/or pain, but 8.7% of the TCu-200 B users did. Yet expulsion or displacement accounted for the leading reasons for removal of the TCu-380 A. Nevertheless the differences in reasons for removal between the 2 copper releasing IUDs were not statistically significant. No one with a TCu-380 A experienced a pregnancy, but the pregnancy rate for those with a TCu-200 B stood at 4 per 100 women-year. 46% of TCu-380 A users were 30 years old. Since higher pregnancy rates have occurred in women 30 years old at insertion than those 30 years old at insertion made the effectiveness rate of TCu-380 A all the more significant. In conclusion, if health workers properly screen women who wish to have an IUD, the TCu-380 A can be as effective in developing countries as it is in developed countries.
