No.
Puberty starts when the pituitary gland signals the adrenals to produce hormones. The time when this happens is controlled by our genes.. so family history affects the ages at which puberty starts
Heredity plays an important role in puberty. The age and time at which puberty hits depends on the parents. Also the extent to which the child grows depends on the parents.
Zero time.
There are millions of possibilities for combinations of the two parents' genes. They don't combine the same way each time. People carry recessive genes for traits they don't show, so each egg or sperm has its own unique combination of genes.
In girls, there is not usually any underlying problem, some boys inherit the condition, it is only inherited in girls about !% of the time. In about 15% of cases there is an underlying problem.
I would suggest that you seek professional medical help.
Trust me they've known for quite some time. There's a certain attitude change in the mood when someone enters puberty. And they have been through it themselves so they know. If you want you can simply just say "I think I'm in puberty".
it just depends on your genes. If your parents are tall you will most likely be tall as well but it also depends on when you hit puberty - some people are small for a long time and suddenly shoot up and are very tall, yet some people are already tall and don't grow much more.
The answer will depend on whose perspective you want: the student's or his or her parents'.
Nearly everyone will hit Puberty without any help from hormone replacement treatment. But if you have no signs of beginning puberty by the time you are in your late teenage years, then you may need a little help getting started. Speak with your Doctor and ask for treatment. They will know what to do for the best of your health. Most children begin Puberty in the early teens or before, but everyone is different, and it depends on your genes you have inherited from parents and grandparents. It may be that late puberty runs in the family, but if not don't worry as it will happen eventually and you will catch up.
It cannot be measured this way. The penis grows at its own rate throughout puberty in direct proportion to the rest of your body. Everyone is different and growth can be quick or slow depending on the genes you inherit. By the time puberty is over you will catch up with any of the quicker to grow peers.
You will be able to get the genes from both sets of parents. This allows for adaptation and evolution to occur over time.
