Fertility after Insertation of an IUCD in Taiwan's Family-Planning Program

Publication Abstract

Freedman, Ronald, Anrudh K. Jain, Albert Hermalin, and Te-Hsiung Sun. 1971. "Fertility after Insertation of an IUCD in Taiwan's Family-Planning Program." Social Biology, 18(1): 46-54.

In a sample of 4648 women who had an IUCD insertion by July 1, 1966 in Taiwan's family planning program, the postinsertion fertility was low in relation to fecundity potential. For those who used IUCDs for limiting family size, only 8% had borne a child 30 months after insertion. Of those who had wanted anotherchild, 40% had borne at least 1 child within 30 months. The postinsertion fertility decline was 65-80% compared with the expected values without contraception. IUCD acceptors, although a highly fecund group, kept birth rates low for 18 months after insertion, regardless of whether their intention was to limit or space births. Women who had previously used abortion or contraception had lower birth rates than others. Of those dissatisfied with the IUCD, only 12% had a birth.
