Timing of puberty[change | change source]

On average, girls begin puberty at ages 10–11; boys at ages 11–12.[1][2] Girls usually complete puberty by ages 15–17,[2][3][4] while boys usually complete puberty by ages 16–17.[2][3] The major landmark of puberty for females is menarche, the onset of menstruation, which occurs on average between ages 12–13;[5][6][7] for males, it is the first ejaculation, which occurs on average at age 15.[8]In the 21st century, the average age at which children, especially girls, reach puberty is lower compared to the 19th century, when it was 15 for girls and 16 for boys.[9] This can be due to improved nutrition resulting in rapid body growth, increased weight and fat deposition,[10] or eating meat from animals which have been dosed up with estrogen.[11][12] Sexual attraction to tweenagers or people going through puberty is called hebephilia.[13]
