Controversial theories have been put forward, including watching too much television could distort the hormonal balance of adolescents and push many of them into early puberty.
Psychologists have said young girls who have close relationships with their fathers might enter puberty later than girls with distant or non-existent links. Now 12 European teams are carrying out research as part of a three-year project to get to the root of the problem, looking at the most likely culprits.
Professor Olle Söder from the Karolinska Institute is leading one study which will look at whether rising obesity rates are to blame.
His team will study whether animals that are overfed produce more of the male and female sexual hormones that trigger puberty.
