伴侶懷孕時 男性真的易出軌嗎(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.
與低水平的唾液睾酮相關的是較高水平的愛情滿意度和忠誠度，男性對婚外性的興趣較低，離婚的機率也較低。
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，似乎在向人父轉變的過程中，父親的睾丸素水平下降，會使其停止尋求新的交配機會，投身於目前的關係及照顧後代。
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.
這項研究由南加州大學的Darby Saxbe帶領，他們追蹤了27對夫妻懷第一胎以及孩子出生後幾個月裏的情況。他們測量了在懷孕期間家長們的睾丸素水平。
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.
孩子出生後的幾個月中，參與調查的夫妻還要對自身的投入度，忠誠度和對伴侶的滿意度進行打分。
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.
該研究小組發現，在伴侶懷孕期間，父親的睾丸素水平出現明顯的下降，並且與母親的睾丸素水平呈顯著的正相關。
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.
在懷孕期間母親和父親的睾丸素水平之間的相關性越好，孩子出生後父親的參與程度越高——父母之間的同步程度預示着父親的投入度、忠誠度和對夫妻關係的滿意度。
