我看这张图比较直观，就拿来用了。虽然没有figure legend， 但以我的经验，这类采样数据是选择不同年龄段的健康couple，统计一年内在without using birth control的前提下的结果；至于男性的年龄，可能没有相关进去。

另有报道：

A women younger than 30 years old was 25% less likely to conceive a baby if her male partner was 40 years or older.

That a woman of 35 to 37 years was 50% less likely to conceive if the male partner was over 40 years old.
