伴侣怀孕时，男性真的易出轨吗？

一项新的研究发现，答案可能是睾丸素。尽管高水平的这种雄性类固醇激素与侵略性和竞争性行为有关，低水平时则促进养育性行为，特别是那些与照顾子女相关的行为。

Previous studies show that fathers who are in a relationship and are more involved with children’s care show lower testosterone levels that men who don’t have children. Lower levels of salivary testosterone have also been tied to higher self-reported levels of relationship satisfaction and commitment, a lower interest in sex outside of marriage and a lower chance of divorce. So it would seem that a father’s decrease in testosterone levels during the transition to parenthood leads him from exploring new mating opportunities towards investment into the current relationship and caring for offspring.

之前的研究表明，处在一段亲密关系中且更多地参与照看孩子的父亲，其睾丸素水平低于没有孩子的男性。与低水平的唾液睾酮相关的是较高水平的爱情满意度和忠诚度，男性对婚外性的兴趣较低，离婚的几率也较低。因此，似乎在向人父转变的过程中，父亲的睾丸素水平下降，会使其停止寻求新的交配机会，投身于目前的关系及照顾后代。

Led by Darby Saxbe of the University of Southern California, the study followed 27 couples expecting their first child during pregnancy and first few months after birth. The parents’ testosterone levels were measured during this pregnancy, and participants rated their investment, commitment, and satisfaction with their partner a few months after their child’s birth.
