The Asian Age - - Science + Health -

The age at which boys be­gin pu­berty is linked to when their moth­ers started hav­ing pe­ri­ods, a study sug­gests.

Moth­ers who started ear­lier than their peers had sons who had: armpit hair two and a half months ear­lier; acne and voices break­ing two months ear­lier.

Their daugh­ters, mean­while, de­vel­oped breasts six months ear­lier. The study, in the Hu­man Re­pro­duc­tion jour­nal, an­a­lysed data from nearly 16,000 Dan­ish moth­ers and chil­dren, BBC re­ported.

The age boys and girls start pu­berty has been grad­u­ally de­creas­ing around the world.
