伴侶懷孕時 男性真的易出軌嗎(1)
A new study found that men show shifts in behavior from mating-oriented to parent-oriented while their partners’ pregnancy develops.
一項新的研究發現，在伴侶懷孕時，男性的行爲會從交配導向型轉變爲家長導向型。
These changes are determined by changes in testosterone levels across pregnancy and hormonal linkage with their partner。
決定這一轉變的是伴侶懷孕期間男性睾丸素水平的變化，以及他們與伴侶之間的荷爾蒙聯動。
It’s almost hard to imagine that every caring dad was once a skirt-chasing ball of hormones — but it’s true. Somewhere along their transition to parenthood, biology puts a stop to men’s carefree days of sowing wild oats and turns their attention towards nurturing children.
難以想象每個慈愛的爸爸都曾是一團追逐女性的荷爾蒙——但這是真的。在轉變爲人父的過程中，生物機制使男性結束了逍遙自在、四處播種的日子，並將注意力轉到養育孩子上。
This is a very solid strategy from an evolutionary point of view, but we didn’t know exactly how it happened.
從進化的角度來看，這是一個非常可靠的戰略，但我們並不確切知道它是如何發生的。
A new study found that the answer may be testosterone.
一項新的研究發現，答案可能是睾丸素。
While high levels of this androgenic steroid hormone have been associated with aggression and competitive behavior, lower levels promote nurturing behaviors, particularly those related to caring for offspring.
儘管高水平的這種雄性類固醇激素與侵略性和競爭性行爲有關，低水平時則促進養育性行爲，特別是那些與照顧子女相關的行爲。
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.
之前的研究表明，處在一段親密關係中且更多地參與照看孩子的父親，其睾丸素水平低於沒有孩子的男性。
