Hormonal changes in girls in 10 years
So, as for the hormonal changes inGirls in 10 years, then during this period there are noticeable changes in the functioning of the body. Thus, for example, the ovaries of girls on a recruiting period (this period, the first phase of which begins with 10-13 years and is caused by the formation of a daily cycle and increased production of estrogen in the ovaries) under a constant regime are aimed at the release of a small amount of the hormone estrogen, whose products are regulated at Help the hypothalamus (part of the brain). This happens through the "feedback" system and allows you to provide support for the concentration of the hormone at a certain and constant level. But at the time of reorganization of the body and the period of puberty, the "tuning" of the hypothalamus changes and in connection with this there is a significant increase in the synthesis of estrogen by the ovaries, which leads to an increased concentration of this hormone in the blood. In connection with this process, in some girls, the total weight of the body can be significantly increased.
Also during this period, hormonal changesOccur not only at the level of increasing the amount of estrogens that circulate in the bloodstream, but over time, there is a change in the amount of progesterone production that is synthesized by the ovaries at the time after ovulation. All these changes significantly affect the majority of the girl's system and consequently lead to different physiological transformations.
Those girls who in 10 years have a lowBody fat content, often lag behind their peers with respect to the period of onset of puberty. First of all, this is due to the fact that the amount of fat in the girl's body is directly related to the production of hormones.
By the way, hormones, usually associated withMale sex - androgens and small amounts of testosterone, are also characteristic of the girl's organism, but they are present in it in very small concentrations. These hormones perform many meaningful functions. For example, they are responsible for the overall growth of hair on the body.
Hormonal leaps and increase in their level inThe girl's organism at the moment of sexual formation can be caused by various changes in the emotional state of the adolescent, for example, emotional variability, frequent changes in mood, a constant sense of anxiety and anxiety.
Hormonal spike and physical changes
At the first stage of puberty, intensive growth of ovaries and other internal reproductive organs begins. The products are erogenous, at this moment they pick up the peak of their activity.
The influence of body fat on pubertalChanges: in girls of dense physique puberty occurs much earlier, and in thin women with low weight, there are delays in physiological changes in the body.
As a result of the increase in the level of hormones inThe girl starts to get feminine forms: the mammary gland is enlarged, the voice is lowered, the pubic hair begins to appear. This process is called the emergence of secondary sexual characteristics. After that, there is a noticeable acceleration of growth, which is stimulated by an increase in the degree of sex hormones, growth hormone and one more element, which is called insulin-like growth factor I. It is precisely for this reason that in the period from 10 to 12 years, girls have growth much higher for their Peers of boys, and after all to fault an active splash of hormones which accompanies practically all period of puberty of girls.
