伴侣怀孕时 男性真的易出轨吗(2)
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.
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。
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.
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.
这项研究由南加州大学的Darby Saxbe带领，他们追踪了27对夫妻怀第一胎以及孩子出生后几个月里的情况。他们测量了在怀孕期间家长们的睾丸素水平。
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.
孩子出生后的几个月中，参与调查的夫妻还要对自身的投入度，忠诚度和对伴侣的满意度进行打分。
The team found that fathers showed significant declines in testosterone while the pregnancy progressed, and a significant positive correlation with the mother’s testosterone levels.
该研究小组发现，在伴侣怀孕期间，父亲的睾丸素水平出现明显的下降，并且与母亲的睾丸素水平呈显著的正相关。
A better correlation between the mother’s and father’s testosterone levels during pregnancy was associated with higher levels of father involvement after the child’s birth — the degree of synchrony between the parents predicted the fathers’ investment, commitment, and satisfaction in the couple relationship.
在怀孕期间母亲和父亲的睾丸素水平之间的相关性越好，孩子出生后父亲的参与程度越高——父母之间的同步程度预示着父亲的投入度、忠诚度和对夫妻关系的满意度。
