Primiparous American women (N = 140) were questioned during their third trimester concerning their choice of sex of offspring and their willingness to use sex preselection techniques (if available). Eighty-two women expressed no preference for sex of offspring; of the remaining 58, 33 chose girls and 25 chose boys. Of the 26 women who indicated they would have used preselection technology, 13 chose boys and 13 chose girls. Fifty-three percent of the sample indicated they would not have used preselection techniques; 29% were undecided. These results were at variance with earlier studies that indicated a consistent choice of male firstborns, especially in nonpregnant samples. The discrepancy is discussed in terms of a move from boy preference to no preference and a gradual weakening of societal bias against women.
对140名初产美国女性在孕晚期进行了询问，了解她们对子女性别选择的情况以及使用性别选择技术（如果有）的意愿。82名女性表示对子女性别没有偏好；在其余58名女性中，33人选择女孩，25人选择男孩。在表示会使用性别选择技术的26名女性中，13人选择男孩，13人选择女孩。53%的样本表示不会使用性别选择技术；29%的人未做决定。这些结果与早期研究不同，早期研究表明一直以来都倾向于头胎生男孩，尤其是在未怀孕的样本中。从男孩偏好到无偏好的转变以及社会对女性偏见的逐渐减弱对这种差异进行了讨论。
