Many male friends feel that their testicles are smaller when they are with their friends after they grow up. They worry about whether there will be any problems and whether it will cause their sexual function to be weaker. Boys are very worried about when they will grow and develop. So, how long will it take for boys with impotence to stop growing and developing? Men can understand it. The growth and development of male genitals involves four key stages. The first stage is during the 10th to 12th week of pregnancy, when the male genitals are just divided and are about 3.5 mm long. The hormone that works at this time is testosterone produced under the action of human chorionic gonadotropin (hCG) in the embryo's metabolism. The second stage is in the middle and late six months of pregnancy. The penis grows rapidly and reaches 2.5-3.5 cm at birth. At this time, the pituitary gland of the fetus has just begun to metabolize gonadotropin. The third stage is from birth to puberty. During this period, the penis grows very slowly. This is because the hypothalamus and pituitary gland grow and develop slowly, and the testosterone level is also low. The fourth stage is when men start to enter puberty at the age of 12-13. The pituitary gland and testes produce sufficient growth hormones. Under the stimulation of testosterone, the male genitals closely bind to the androgen kinase in the corpus cavernosum and grow rapidly. In just 5 years, they can reach the adult level. For most men, male maturity is around 18-20 years old. At this time, the male genitals have basically completed their growth and development, and have stopped growing and developing. Many people also ask, will the male genitals continue to grow and develop after the age of 30? As mentioned before, generally speaking, the male genitals stop growing and developing at the age of 20. Therefore, for adult men at the age of 30, it is basically difficult for the male genitals to grow and develop again. |
