A group of researchers at the Edinburgh University has been claiming after its recent study that early maturity of girls is a possible outcome of hormone imbalance caused by broken families.

Professor Richard Sharpe from the team says that hormonal imbalance in girls often occurs due to father's absence or separated family. Also, some other reasons may be obesity or even anxiety caused by modern relationships, he added.

It has been found that parents often put pressure on girls to score and perform well at school and the same may be a cause of their long-term stress.

A previous study, including 440 girls from all backgrounds, whose fathers did not live with them, has revealed that these were at 2.4 times more risk of developing breast tissues at a young age. It was noted that some had begun to grow breasts at the age of nine, while some others tended to develop the same at seven only.

The team this time says that early puberty not only risks girls to experience premature sexualization, but also teenage pregnancy. It is being said that the male hormone androgen that are produced naturally during puberty, tend to release earlier and in large quantities.
