Brother stops girl growing up

研究:家有兄弟女孩'慢熟'

They may pull their sister's pigtails and tease her mercilessly about her spots. But a girl's brothers also have a crucial effect on the woman she becomes, the Daily Mail of London reported. Girls with elder brothers go through puberty later, while those with younger brothers wait longer before having a sexual relationship, research shows.

作為兄弟，他們揪妹妹的小辮，嘲諷姐姐的痘痘。但是，他們更關鍵的作用是：決定自己的姐妹長成怎樣的女人。據英國《每日郵報》報道，研究顯示，有哥哥會使女孩的青春期推遲，而有弟弟會使她的性生活來得更晚。
