On average, today's teenage boys reach puberty one year earlier than their fathers, according to a study by American researchers in Bulgaria.The study, published in the journal Archives of Pediatrics and Adolescent Medicine, compared some of the body data of 6,200 healthy Bulgarian boys with a similar study conducted in the 1970s by Cedars Sinai Medical Center in Los Angeles.
Today's boys ripen earlier than before
Both studies measure the height, body weight, testis volume and penis length and necropsy of the boys. As research leader Fnu Deepinder said in the previous study, between the ages of 13 and 16 years, the sexual development stage, according to the same study has steadily increased from birth, from about 5 centimeters to about 9.5 centimeters. The volume of testes did not increase significantly until puberty, but then it changed dramatically. Both variations were greatest between the ages of 12 and 16, and the height and weight of the males increased most between the ages of 12 and 14.
Researchers have found that at a given age, boys' penis size is now larger than it was in the 1970s, but its final size, which is reached by the age of 17, has not changed.
