Comparative assessment of the reproductive function of adolescent girls
The International Symposium on Age Periodization (1965) recommended the adolescence to be considered the period from 12 to 15 years, and youthful — from 16 to 20 years. During adolescence, not only the anatomical formation is completed, but also the functional maturation of both the genitals and the central regulatory departments. During puberty, there are 2 to 3 phases. The first stage - prepubertal - is characterized by a growth spurt, the development of the pelvic bones, the manifestation of menarche, a decrease in growth hormone, an increase in the level of gonadotropins and estrogens, and activation of the thyroid gland.
