The fashion for having children later in life could lead to women becoming more fertile in their 40s and beyond, scientists have suggested.
科學(xué)家指出,現(xiàn)在的晚育趨勢(shì)將讓未來(lái)女性40歲以后的生育能力增強(qiáng)。
As many women wait until they are older to give birth, only those with longer lasting fertility genes will be successful.
許多女性會(huì)等到年齡很大時(shí)才生育,而只有那些帶有更持久的繁殖基因的女性才會(huì)成功晚育。
That means the average length of fertility will grow as their genes will be passed on to their children.
這意味著生育能力持續(xù)的平均時(shí)間會(huì)隨著她們的基因遺傳給下一代而變長(zhǎng)。
