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 testo
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.
jump in growth is not in vain called just that - at that time a person is growing so fast that the hose is constantly becoming shorter and pants look as if before they were younger brothers or sisters.This continues for two to three years, and at the peak of growth spurt person can grow more than 10 cm per year.After the end growth spurt body will no longer grow - until the end of life will increase as it became in the period of puberty.(It should be noted that there are diseases of which the man continues to grow, even when puberty ends - in these cases, doctors need help, in addition, old growth can be reduced by 3-5 cm).
During puberty, the body not only gets higher - happen to him and other changes.Body weight increases.The young men's shoulders are wider, there are more muscle tissue.The voice becomes lower - after a period of breaking vote, during which he can sound a little too low, but too high.The penis becomes longer and wider, the testicles increase.
Body girls becomes more pronounced curves, it increases the amount of adipose tissue - especially in the hips and chest.Sometimes one breast grows faster than the other, but in most cases, after a while they become the same size.The deposition of subcutaneous fat in some parts of the body is the norm for women and adolescent girls are not recommended to sit on a diet or trying to lose weight in other ways, as long as their bodies have not issued the final.If you suspect that overweight should consult a doctor.
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.
Trouble with skin
With puberty comes something else - acne and acne Acne: facial trouble , or acne.Only about 20% of teens go through puberty with a perfectly clean skin Clean skin: the beauty of the need to fight .
