Within 2 years 258 women aged 16 to 42 years were fitted with a copper-7-IUD (Gravigard, Searle). 45% of these patients were nulliparous women. Follow-up studies were provided in 236 cases in a total of 2717 women-months according to an average time of observation of 11.5 women-months per patient. Altogether there occurred 5 unwanted pregnancies …….. Partial or total expulsion occurred in 27 cases (11%)……..Removals for medical reasons were requested in 36 cases-in the majority (26 cases) because of bleeding and pain…….The continuation rate after 2 years was 73%. The highest number of drop-outs occurred within the first year after insertion (60 cases = 23%) whereas only 4% drop-outs occurred in the 2nd year. ………The most important side effects of the copper-7-IUD in situ were irregular bleeding, intermenstrual pain and discharge. Irregular bleeding and pain decreased markedly after the first year, while slightly prolonged periods persisted in 30 to 50% of all patients….
