Long-Term Use of Contraceptives by IUD Acceptors in Taichung, Taiwan

Abstract

Extrapolations from relatively short periods of observation on IUD acceptors suggest that the IUD has a limited antifertility effect, but reports from Taiwan permit more optimistic forecast. The study sample consisted of 5832 urban women in Taichung, Taiwan who accepted an IUD in the period of July 1962 to May 1965. At 60 months since the 1st IUD insertion 31.1% were using the IUD. Termination rates appear to have declined because there is not as much bleeding connected with the IUD, and reinsertion rates are increasing. Sterilization seems to be the most important competitor of the IUD.
