RESUMO
PIP: A group of 600 IUD users aged 26 to 35 were studied. 440 women were married; 434 were pluriparae and 166 nulliparae. 24 (5.5%) had undergone cesarean section, and 266 (44.3%) had had induced abortion. 23% of single women had opted for voluntary termination of pregnancy, while 72% had previous experience with IUDs or oral contraceptives. 273 (45.5%) relied on behavioral methods of contraception, 33 (5.5%) used the diaphragm, 279 (46.5%) used pills, 124 (20.6%) used condoms (50.6%) used ML-250 IUD, 144 (24%) used Progestasert, 87 (14.5%) used Gravigard, 42 (7%) used Minigravigard, 18 (3%) used Nova-T, 4 (0.6%) used Anticon, and 1 (0.1%) relied on No-Gravid. The IUD was removed prematurely in 119 cases, 339 were removed at the end of usefulness, dropout occurred in 51 cases, and expulsions in 14 cases. IUD failure was registered in 103 cases corresponding to 21.8% of the total. Bleeding caused 31 instances, 22 were due to dislocation, there were 15 intra -uterine pregnancies, 14 expulsions, 11 cases of pelvic pain, 4 cases of pelvic inflammatory disease, 3 cases of extrauterine pregnancy, and 3 other failures of IUDs. 31% of failures occurred in the 31-35 age group, and 40% of nulliparous women had IUD experience, but only 22.8% had a positive experience. 83.9% of those who used progesterone-containing pills had success with them, only 16.1% failed. Pluriparae over 30 used Progestasert most successfully. Nulliparous women did not represent the ideal candidates for IUD use, previous positive experience was an important element of success, while less important factors were age and abortion history.^ieng
