人们普遍承认，过了一定年龄的女性生育力会下降，但有关自然生殖的支持数据却很少。 （我们使用“生育力”一词的意思是“生育能力”；“生育力”表示实际生育。）在对三项大型研究数据的分析中，莱里登提出，30 岁以上女性的生育力会下降。1然而，这一群体包括各个年龄段的女性。此外，无法从数据中确定生育力的下降是生物学原因还是仅仅是性活动减少的结果。人为的。 。 。
THE decrease in the fecundity of women who have passed a certain age is generally acknowledged, but supporting data on natural reproduction are scarce. (We use the term "fecundity" in the sense of "capacity for procreation"; "fertility" denotes actual procreation.)

Furthermore, it was not possible to determine from the data whether the decrease in fecundity was biologic or simply the consequence of diminished sexual activity.Artificial . . .
