This article has three goals. First, we compare late childbearing in the United States and several European countries. We then discuss the physiological aspects of late fertility and review recent analyses of the extent to which assisted reproductive technologies affect the probabilities of conceiving and having successful pregnancies at advanced childbearing ages. Finally, we present analyses of late and very late fertility in Sweden, a country for which the relevant data are of high quality, cover a long time period, and permit calculation of conventional age-specific fertility rates, as well as occurrence-exposure rates that eliminate the influences of shifts in the parity distribution.

Abstract

This article has three goals. First, we compare late childbearing in the United States and several European countries. We then discuss the physiological aspects of late fertility and review recent analyses of the extent to which assisted reproductive technologies affect the probabilities of conceiving and having successful pregnancies at advanced childbearing ages. Finally, we present analyses of late and very late fertility in Sweden, a country for which the relevant data are of high quality, cover a long time period, and permit calculation of conventional age-specific fertility rates, as well as occurrence-exposure rates that eliminate the influences of shifts in the parity distribution.
