Abstract

A review of published reports showed that the sex ratio (proportion of boys) was low among infants conceived after ovulation had been induced. The difference between the observed sex ratio and an expected one of 0 . 514 was highly significant. These findings suggest that maternal gonadotrophin concentrations at the time of conception directly affect the sex of the zygote.

摘要

对已发表报告的回顾显示,在诱导排卵后受孕的婴儿中,性别比(男孩比例)较低。观察到的性别比与预期的0.514之间的差异非常显著。这些发现表明,受孕时母体促性腺激素浓度直接影响受精卵的性别。
