The estimation of fecundability from survey data is plagued by methodological problems such as misreporting of dates of birth and marriage and the occurrence of premarital exposure to the risk of conception. Nevertheless, estimates of fecundability from World Fertility Survey data for women married in recent years appear to be plausible for most of the surveys analyzed here and are quite consistent with estimates reported in earlier studies. The estimates presented in this article are all derived from the first interval, the interval between marriage or consensual union and the first live birth conception.
根据调查数据估算受孕能力存在诸多方法学问题，比如出生日期和结婚日期误报，以及婚前受孕风险暴露情况。尽管如此，对于近年来结婚女性，世界生育率调查数据得出的受孕能力估算值在本文分析的大多数调查中似乎是合理的，并且与早期研究报告的估算值相当一致。本文给出的估算值均来自第一个间隔期，即从结婚或双方自愿结合到首次活产受孕之间的间隔期。
