Nationally representative estimates of time-to-pregnancy (TTP) and infertility based on a clinical definition of 12 months have been limited within developing countries. The described approach represents a pragmatic advance in our ability to measure and monitor infertility in the developing world, with potentially far-reaching implications for policies and programs intended to address reproductive health. The analysis suggests that a current duration (CD) approach applied to Demographic and Health Survey (DHS) data from Nigeria provides infertility prevalence estimates comparable to other smaller studies in the same region.
