Whilst one should not fight to achieve this, there are various causes of this to happen.

Some of the causes in the industrialized world have been various hormones used on live stock. Some girls have started their period earlier than normal because of this or similar.

Another cause seen on many adopted children from the "third" world is that the human Biology is made in a "reproductive" sense.

When there is little food around, there is normally problems involved. Girls simply can not become pregnant because the body does not get enough nutrition to sustain a baby.

When there is a lot more food around, after starving for a long time, this can in many cases kick-start periods.

This is believed to be the main cause of making children from the "third" world mature before time. Some can even start having periods at age 3.

Medication is today a sort of fail proof method in order to start off a girls period.

Doctors do not normally do this at all. The periods will start when your body is ready for it.
