A comparison has been made between Lippes loop and T Cu 200 intra-uterine contraceptive device with respect to their acceptability and effectiveness in a developing country. A total of 1054 patients were studied; 697 with Lippes loop and 357 with T Cu 200. The ages of the patients ranged between 14 and 44 years, with a peak age of 21-25 years for T Cu 200 and 26-30 for Lippes loop. The event rates were similar but T Cu 200 displayed lower expulsion rate, lower intermenstrual bleeding rate and a lower incidence of pelvic inflammatory disease. The Lippes loop had lower event rate for the other parameters considered, pregnancy and pelvic pain. The continuation rate was similar for both devices. Both devices are useful for women who wish to space out their children but for those who wish to achieve effective contraception for more than 5 years, Lippes loop should be the IUD of choice.

The relationship between the use of intrauterine contraceptive device (IUD) and pelvic inflammatory disease (PID) was examined in 1054 patients who were seen at the Family Planning Clinic of Jos University Teaching Hospital and were followed up. The overall risk of PID developing in women wearing the IUD was minimal: 62 out of 1054 (5.9%). The rates, however, varied for the 6-month periods studied. The incidence of PID decreased as the period of usage increased. The greater number of patients developed PID less than 3 months from the date of IUD insertion. When PID occurred it was usually of mild or moderate intensity and the response to antibiotic therapy was very encouraging. There was no relationship between the parity of the patients and the development of PID. Even though there is a definite link between the use of IUD and the development of PID it does not obliterate the benefits which the use of IUD provide for the majority of its patrons; and so the use of IUD should continue.
