How do men maintain their lower body? Many people think that there is no secretion in the private parts of the lower body of men, and they do not need to wash frequently. This idea is wrong. There are many wrinkles in the lower body of men, and the skin is thin. The secretion of sweat is easy to cause bacterial breeding. So how do men maintain their lower body?
There are many vaginal secretions in women. It seems natural to scrub the lower body. For thousands of years, Chinese women have formed a habit. However, men rarely have the habit of washing their bodies. In fact, men should also wash their bodies regularly. This habit should be formed from the time of young men.
Male reproductive organs are divided into internal and external parts. The internal genitalia includes testis, vas deferens and accessory glands; The external genitalia includes the scrotum and penis. These organs develop very slowly before puberty. After puberty, they begin to develop rapidly under the influence of follicle-stimulating hormone, luteinizing hormone and androgen, and their speed is far faster than other systems. The scrotum is a small wrinkled pocket formed by the skin of the abdominal wall, which is darker than the surrounding skin. The scrotum is divided into two halves, which are connected in the middle. There is one testicle and one epididymis in each of the two halves.
The skin of the scrotum is elastic, with many wrinkles on the surface. It relaxes when the temperature is high, and the sebaceous glands and sweat glands secrete vigorously to accelerate heat dissipation; Shrink when the temperature is low, reduce heat dissipation, and close to the body. This automatic regulation function of the scrotum is mainly to protect the spermatogenic function of the testis. The penis is a male sexual organ, and its front end is Ding Ding, rich in nerve fibers, which is the most sensitive part. After one year of testicular development, the penis began to increase and thicken, and the development was as adult level at the age of 17-18 years. A thin layer of skin wrapped around Ding Ding is called foreskin.
How does a teenager's genitals change?
At the beginning of puberty, due to the rapid enlargement and thickening of the penis, the foreskin gradually recedes to reveal Ding Ding. If the foreskin is still covered with Ding Ding after puberty and can only be exposed after turning, it is called the foreskin is too long; If it cannot be turned out, it is called phimosis, and requires surgical treatment. There is often foreskin scale accumulated in the foreskin. During the youth development period, foreskin scale is more frequent. You should often turn over the foreskin and wash it to avoid causing Ding Ding and foreskin inflammation. Testis is the most important part of male genitalia, which is a pair of oval glands. The testicular volume before puberty is only larger than that in infancy, less than 3ml. After puberty, the testicles develop rapidly with a volume of more than 12 ml. The length and tortuosity of the inner convoluted tubules increased, the lumen thickened, the spermatogonia on the basement membrane of the tube wall continued to divide and reproduce, and spermatogenic cells of various stages appeared, and finally developed into sperm. The testis also secretes male hormones, so the testis is both a reproductive organ and an endocrine organ.
In the fetal period, the testicles are in the abdominal cavity. After birth, the testicles fall into the scrotum. Some boys have no testicles in the scrotum or only one side. This is because the testicles still remain in the abdominal cavity without falling down. It is called "cryptorchidism" in medicine, and should go to the hospital for examination and treatment as soon as possible. The accessory glands of male reproductive organs include seminal vesicle, prostate gland, bulbar gland of urethra, etc. After the onset of puberty, the above glands all develop rapidly and secrete liquid, and form thick milky semen after mixing with sperm. Sperm emission is a physiological phenomenon peculiar to men and an important sign of puberty. After puberty, it can occur in healthy men.
The average age of first ejaculation is 14~16 years old, about 2 years later than the average age of menarche of girls. The first spermatorrhea usually occurs in summer. There may be no mature sperm in the initial semen. After the first ejaculation, the physical development gradually slowed down, while the testicle, epididymis and penis developed rapidly, close to the adult level. Adolescent men, with the development of their reproductive organs, have secondary sexual characteristics such as hair growth, voice change and laryngeal nodules. Pubic hair appeared first, followed by axillary hair. One year after the appearance of axillary hair, it grows beard. Protrusion of the larynx node is the second characteristic of men.
Why should young men also form the habit of washing their bodies often?
As mentioned earlier, the skin of the scrotum and penis has many wrinkles, sweat glands and strong secretion, especially the poor ventilation. Wearing chemical fiber underwear and tights will make the ventilation worse. Therefore, a large amount of sweat, dirt, residual urine, unwashed fecal residue, semen, etc. will pollute the whole penis, scrotum and perineum, and bacteria can easily grow and breed in this environment. If not cleaned in time, it will not only emit a bad smell, It is also not conducive to skin health care, and is prone to cause diseases such as butyritis, urethritis, prepuceitis, scrotal eczema, tinea cruris, and even penis cancer. If you have sex with a man whose lower body is dirty, you will also bring these dirty dirt, secretions, bacteria and microorganisms into the female vulva and vagina, which will affect the cleanness of the female vulva and vagina, and even cause vulvitis, vaginitis, cervicitis and other diseases.
So men should also form the good habit of washing their lower body with warm water before going to bed. The water for washing the lower body should not be too hot. First wash the genital organs and then wash the anus. After washing the anus, you can't wash the genital organs again with the same basin of water. The order of drying is to wipe the genital organs first, and then the anus. Don't use the same towel to wipe the genitals after wiping the anus. Some people try to save time and wash their lower body with foot wash, but they do not know that they will bring the mold of tinea pedis to the perineum, which is very easy to cause tinea cruris. You can't wipe your lower body with a towel to wipe your feet. You should prepare a separate towel to wipe your lower body. After wiping, wash with clean water and dry for use.
