Abstract

PIP: This statistical evaluation of human fertility following the discontinuance of intrauterine contraception uses as its main source of data the Cooperative Statistical Program. On January 1, 1968, files contained 746 reported women who had IUDs removed because the couple wanted a child. Of these 611 were followed for at least 3 months after removal. 527 or 86% were known to have conceived. Younger women conceived at higher rates than older ones. Longer use of the IUD decreased conception rates. Fertility rates following discontinuation of oral contraceptives is less available and reported statistics are thought to be inadequate. Clinical observations indicate a high percentage of women conceive promptly after discontinuance of oral contraceptives.
