Features of adolescence and adolescence
The exact time when the child enters the processpuberty, depends on several factors, such as genetics, sex and diet. During this period, endocrine glands actively produce hormones that determine the characteristics of adolescence: the characteristic physiological changes and the development of secondary sexual characteristics. In the ovaries in girls, the production of estrogen and other female hormones increases, and in boys the production of testosterone increases. Endocrine glands produce substances that cause intense sweating, the appearance of characteristic odors, acne, hair and hair in the armpits - these are all features of development in adolescence. At this time, the child may need to use a deodorant and other personal care products.
Peculiarities of adolescence in girls

- rapid growth;
- a noticeable increase in thigh size;
- the appearance of transparent or whitish vaginal discharge;
- growth of hair in the armpits, on the legs and pubic.
Periodicity of the menstrual cycle
Menstruation occurs about once a month,or rather, after a time interval of 28 to 32 days. However, at first it may be irregular: it may take 2 months or 2 weeks between cycles. Soon their manifestation will become more systematic. Watch the periodicity of the menstrual cycle to be able to detect significant abnormalities, if they occur.
Physiology of the menstrual cycle
After the onset of menstruation, the ovaries beginget rid of the eggs that have been there since the birth of the girl. Each month, a female embryonic cell is isolated, which moves along the fallopian tube that connects to the uterus. When the cell reaches the final path, the walls of the uterus are filled with blood and liquid. Thus, during fertilization, the cell can grow and develop under suitable conditions. If the germ cell does not occur with sperm, it dissolves. The densified layer lags behind the uterus and forms menstrual blood, which is eliminated from the body through the vagina. Vaginal discharge between menstruation is normal.
