Puberty in boys linked with mothers’ cycles
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.
