A method for estimating conception rates, using vital statistics data, is developed and applied to data on five-year age groups of California women for 1971. The approach is deterministic and allocates total exposure time to the known pregnancy outcomes of live birth, spontaneous abortion, and induced abortion. The population at risk is defined to exclude women who are known to be sterile or sexually inactive. Early fetal loss, premarital conception, and contraceptive use are taken into account. Estimates are made of the fecundability which would obtain if no contraception were used.
一种利用人口动态统计数据估算受孕率的方法被开发出来，并应用于1971年加利福尼亚州女性的五年年龄组数据。该方法是确定性的，将总暴露时间分配给已知的活产、自然流产和人工流产等妊娠结局。定义的风险人群排除了已知不育或无性活动的女性。考虑了早期胎儿丢失、婚前受孕和避孕措施的使用情况。对在不使用避孕措施的情况下可能获得的生育力进行了估计。
