Although intrauterine devices (IUDs) are a highly cost-effective contr
aceptive method, they have been unfortunately associated with increase
d risk of pelvic inflammatory disease (PID). However, new studies, inc
luding a 1992 World Health Organization (WHO) report, have demonstrate
d that there is little evidence of a causal link between IUD use and P
ID. IUD-related risk of PID is increased only during a short period fo
llowing insertion, and exposure to STDs is probably the major determin
ant of PID risk for IUD users. Furthermore, no increased risk of PID u
se has been demonstrated with long-term IUD use. This paper examines t
he evidence, focusing on the 1992 WHO study, and looks to the future w
ith suggestions for IUD research and programmatic approaches in the ho
pe of vindicating the IUD's reputation and broadening the indications
for its use.
