When a person reaches a certain age, his brain begins to produce gonadotropin-releasing hormone, or GnRH.It stimulates the pituitary gland and, in turn, begins to produce two hormone concentration in the blood during puberty significantly increases: luteinizing hormone (LH) and follicle stimulating hormone (FSH).These hormones are present in the bodies of both girls and boys, however, depending on the gender of the person, they influence the development of different parts of the body.
in men LH and FSH triggers the start of testosterone Five myths about testosterone and sperm.Testosterone - a hormone that is responsible for most of the changes occurring in the body of a young man with puberty.
The female body LH and FSH act on the ovaries, which begins to produce the hormone estrogen Estrogen - the key to healthy bones .This hormone, in combination with LH and FSH the body prepares girls for the future motherhood.From the point of view of physiology, puberty hormones are made from adult children - this is due to higher levels of sex hormones to the "adult" level.After this period the person is ready to fertility - at least physically.
Puberty begins between the ages of seven and thirteen girls and nine to fifteen years - the young men.In some cases, puberty may start a little earlier or later.

On average, over 2-2.5 years after girls' breasts begin to grow, they begin the first month.This is one of the most important features by which we can understand that puberty proceeds normally, and hormones are doing their job.
maybe not everywhere, but almost everywhere - at least, so it seems the teenager, who until now had no problems with unwanted hair.Do boys and girls during puberty hair starts growing in the armpits, pubic hair, they become much more upright.By the end of puberty in boys also start to grow hair on the face and chest, sometimes - on the back.The growth of facial hair in women is a sign of hormonal failure - such problem should contact a doctor.
