In terms of gender, girls start to mature and complete their growth are about 2 years earlier than boys.However, with the improvement of the current nutritional conditions and the improvement of health and living standards, adolescence has become more and more advanced.Adolescent physical development includes reaching adult height and weight, muscle bone growth.Except for the size of the lymphatic organs and the stagnation of the brain, the volume of all other organs has increased. The fastest period of boys is 13 to 16 years old. Children's growth is completed by 99%of the age of 18, but once sexual development is launched, the boyBoth with girls follow a certain order of development.
The boy began to increase the scrotum and testicles, and then the development of pubic hair, storage of semen and prostate.Generally, physical growth accelerates in about one year after the testis starts.About 2 years after pubic hair appear, armpit hair and beards appear, and they see mature sperm at the age of 14 to 16 and have nocturnal emission.But it did not reach the maximum fertility until the age of 20.
Sexual puberty means that the boy appeared in sexual maturity before the age of 10.Increased sex gland and maturity, the development of second sexual characteristics, the concentration of steroids in serum reaches the level of adult, and has sperm production. The phenomenon of nocturnal emission occurs. This precocious phenomenon is called precocious nocturnal emission.It often causes mental tension to patients and parents, and is even overwhelmed.And this precocious nocturnal emission is found in those with precocious puberty. 60%of the causes have primary organic changes, such as the damage of the hypothalamus, intracranial tumors, and a few other rare causes.
For the treatment of precocious nocturnal emission, we must first find out the cause, relax the mental of children, cooperate with parents, and relieve unnecessary spiritual burden.There are two aspects of the treatment of drugs, namely the agonist of the anesthesia to release hormones-the luteal formin to release hormone analogs. These drugs can be used until normal adolescence.In addition, non -promoting adenocyrin dependence is precocious, and the use of androgen antagonists can improve the effect of excessiverogens. For example, you can use the body to relax 1.5mg/kg · day, and take 3 times.However, due to the premature development of this premature child, the bones are closed too early, and the height of the height is often short when mature. It should be treated with appropriate growth of hormone.
