并绘制了不同年龄段的受精率曲线（相对于20-24岁的水平）。曲线的上升部分是根据调和平均法从台湾第一次受孕延迟的数据估计的;下降部分是根据婚姻生育率的拟议模型从Hutterite数据估计的。假设各年龄组妇女的生育能力不同，年龄效应相同。估计的生育力下降路径与生育率下降路径不同。
A curve of age-specific fecundability ratio (to the level at age 20-24) was estimated. The rising part of the curve was estimated from Taiwanese data of the 1st conception delay according to the harmonic mean method; the declining part, from Hutterite data according to a proposed model of marital fertility rate. Heterogenous fecundabilities and homogenous aging effect among women in each age group were assumed. The estimated declining path of fecundability was different from that of the fertility rate.
