| Abstract: | The timing of IUD insertion has important implications for those who insert the devices as well as the users. In 1978 the US Food and Drug Administration recommended insertion during menstruation but acknowledged that it is also "necessary and proper" to insert IUDs at other times in the cycle. A 1977 study found that 30% of European and North American obstetricians limited insertion to the time of menstruation. Nearly half those in Africa and the Middle East and 13% of those in Asia followed this practice. Consequently, many women are required to make more than 1 visit to a clinic, meaning inconvenience for both the user and provider and some unintended pregnancies. In developing countries women may depend on mobile clinics or infrequent visits by trained personnel and many seek help without an appointment. 1 reason for insertion at or just after menstruation is to ensure that the woman is not pregnant when the IUD is inserted. 2 recent articles attempt to assess the best time for IUD insertion with regard to IUD performance. White et al. found that women whose Copper T IUDs were inserted on days 1-5 of the menstrual cycle had a lower continuation rate in the 1st few months than did those whose IUDs were inserted at a later time in the cycle. Edelman et al. found that Copper T and Copper 7 IUDs could be inserted at any time during the menstrual cycle without any increased risk of subsequent pregnancy, removal for medical reasons or expulsion during the 1st 12 months after insertion. Pooled International Fertility Research Program (IFRP) data indicate that there is no consistent pattern with regard to the time in the cycle that the IUD is inserted and its later performance. In no case is there a distinct advantage for the 1st 5 days of the menstrual cycle. It is much simpler to offer a woman an IUD when she is first seen, provided she is reasonably sure she is not pregnant. New practices are evolving in relation to recently pregnant women. The postabortal use of IUDs has been extensively researched and is a useful option, using a variety of currently available devices. In regard to the postpartum use of IUDs, some programs have reported a high expulsion rate. Provided proper insertion technique is used, IUDs can be inserted immediately postpartum with a high degree of retention. Another use for copper containing IUDs is insertion within 5 days of unprotected sexual intercourse. In sum, women can be provided with IUDs upon request at any time during the menstrual cycle. |
