Puberty

Let's talk about adolescence in adolescence. When you say puberty, what do you think first. Well, sex is the most common idea emerging from the hearts of many people. But puberty is more than just sex. Adolescence is a very unique and important evolutionary stage for all men and women. During puberty, men and girls experienced many changes, and we may think that it is funny, scary and strange. During adolescence, the testosterone and estrogen levels of boys and girls are greatly increased.

Early onset adolescence is divided into two types, central precocious puberty (sometimes denoted "true precocious puberty") and peripheral early puberty (sometimes "premature puberty puberty "Is displayed). Central early puberty is caused by early activation of the GnRH pathway and is suitable for medical treatment. Peripheral early puberty is caused by gonadal or adrenal gland secretory hormone, it is irrelevant to pituitary signal and is not suitable for treatment. Early childbirth is rare, especially for boys. In a recent Spanish study on central premature puberty, the prevalence of the overall population is estimated at 19 per 100,000 (37 affected girls, 0.46 boys). Danish studies on early onset adolescence (not limited to central premature puberty) have found that the prevalence of females is between 20 and 23 per 10,000 people and between 5 and 10,000 among boys It was.

Gonadotropic hormone - dependent early puberty. This form of precocious puberty, also known as central precocious puberty, is the most common and affects most girls with this disease and half of the boys with this disease. Puberty is caused by premature secretion of gonadotropic hormone, the hormone responsible for puberty. Researchers believe that the prematurity of the hypothalamus - pituitary - ovarian axis may cause this disease in girls. However, in most cases, no cause of premature secretion of gonadotropin was found.

Pubertal preterm is called precocious puberty, characterized by the early development of sexual characteristics of girls aged 8 and older, and in most boys most children with this disease grow initially very quickly, but complete The inheritance that reaches is also completed before the heredity. High likelihood Early adolescence and sexual development may be caused by the growth of tumor or ovary, adrenal gland, pituitary gland or brain. Other causes include central nervous system abnormalities, family history, or rare hereditary syndromes. In many cases, the cause of the disease was not found. Two types of early onset adolescents are included:

The age at which puberty begins depends on the person; usually, adolescence begins between 10 and 13 years old. The age at which puberty begins is affected by genetic factors such as genetic factors, nutritional status, and social environment. As an example of the social environment, young women who have a Vandenberg effect and show significant interaction with adult men enter early adolescence than young women who are overly related to underage men. The average age at which adolescents begin may also be influenced by race. For example, in the various population surveyed, the average age of menarche is 12 to 18 years old. The earliest onset of adolescence is the latest average incidence of African-American girls and self-sufficiency populations in Asian highlands.
