How do men maintain their lower body? Many people think that there is no secretion in the private parts of the male lower body and does not need to be cleaned frequently. This idea is wrong. Men's lower body has many wrinkles and thin skin, and bacteria can easily breed after sweat is secreted. So how do men take care of their lower body?
Women have a lot of vaginal secretions, so scrubbing their private parts seems to be a natural thing. For thousands of years, Chinese women have developed a habit. Men rarely have the habit of washing their private parts. In fact, men should wash their private parts frequently. This habit should be developed in adolescence.
The male reproductive organs are divided into two parts: inner and outer parts. Internal genitals include testicles, vas deferens, and accessory glands; genitalia include the scrotum and penis. These organs develop very slowly before puberty. After puberty, under the influence of follicle-stimulating hormone, luteinizing hormone and androgen, it begins to develop rapidly, and its speed is much faster than other systems. The scrotum, a small wrinkled pocket formed from the skin of the abdominal wall, is darker than the surrounding skin. The scrotum is divided into left and right halves, connected in the middle. There is a testicle and an epididymis on the left and right sides.
The scrotal skin is elastic, with many wrinkles on the surface. It relaxes when the temperature is high, and the sebaceous glands and sweat glands secrete strongly, accelerating heat dissipation. When the temperature is low, it contracts, reduces heat dissipation, and moves closer to the body. This self-regulating function of the scrotum is mainly to protect the spermatogenic function of the testicles. The penis is the male sexual organ. The front end is the penis, which is rich in nerve fibers and is the most sensitive part. One year after the testicles develop, the penis begins to grow larger and thicker, and becomes an adult at the age of 17-18. The thin layer of skin surrounding the penis is called the foreskin.
How do adolescent genitals change?
At the beginning of puberty, as the penis rapidly becomes larger and thicker, the foreskin gradually recedes to expose the penis. If the foreskin is still wrapped around the penis after puberty and needs to be turned over to expose it, it is called foreskin; if it cannot be turned out, it is called phimosis and requires surgery. There is often accumulation of smegma in the foreskin. Smegma occurs more frequently during adolescence. Always turn the foreskin over and wash it to avoid inflammation of the penis and foreskin. The testicles are the most important part of the male genitals and are a pair of oval glands. The testicular volume before puberty is only larger than that of infancy, less than 3ml. After puberty, the testicles develop rapidly, reaching a volume of more than 12 ml. The length and curvature of the inner convoluted tubules increase, and the lumen becomes thicker. The spermatogonia on the basement membrane of the tubule wall continue to divide and reproduce, and spermatogenic cells appear at each stage, eventually developing into sperm. The testicles also secrete male hormones, so the testicles are both reproductive and endocrine organs.
During the fetal period, the testicles are in the abdominal cavity and only descend into the scrotum after birth. Some boys have no testicles in their scrotum or only have testicles on one side. This is because the testicles remain in the abdominal cavity, which is medically called "cryptorchidism". They should go to the hospital for examination and treatment as soon as possible. Accessory glands of male reproductive organs include seminal vesicles, prostate, bulbourethral glands, etc. After puberty begins, the above-mentioned glands develop rapidly and secrete fluid, which mixes with sperm to form thick, milky semen. Nocturnal emission is a physiological phenomenon unique to men and an important sign of pubertal development. It occurs in healthy males after puberty.
The average age of first nocturnal emission is 14 to 16 years old, which is about 2 years later than the average age of menarche for girls. The first nocturnal emission usually occurs in summer. The initial semen may not contain mature sperm. After the first nocturnal emission, body development gradually slows down, while the testicles, epididymis, and penis develop rapidly, approaching adult levels. With the development of reproductive organs during puberty, secondary sexual characteristics such as hair growth, voice change, and Adam's apple appear. Hair appears first, followed by armpit hair. A year after the appearance of armpit hair, beard grows. A protruding Adam's apple is a secondary sexual characteristic unique to men.
Why do boys develop the habit of washing their private parts frequently?
As mentioned before, the scrotum and penis have many wrinkles, sweat glands, and secretions, especially poor ventilation. Wearing synthetic underwear and tight pants will make ventilation poor, so a large amount of sweat, dirt, residual urine, unwashed feces and semen will contaminate the entire penis, scrotum and perineum, and bacteria can easily grow and multiply in this environment. If it is not cleaned in time, it will not only stink, but also be harmful. If you have sexual intercourse when the male lower body is unclean, these unclean dirt, secretions, bacteria, and microorganisms will also be brought into the female vulva and vagina, affecting the cleanliness of the female vulva and vagina, and even causing vulvitis, vaginitis, Cervicitis and other diseases.
Therefore, men should also develop a good habit of washing their private parts with warm water before going to bed. The water for washing the lower body should not be too hot. You should wash your genitals first and then your anus. After washing the anus, do not use the same basin of water to wash the reproductive organs. In the order of drying, wipe the genitals first, then the anus. If you wipe your anus, don't use the same towel to wipe your genitals. In order to save trouble, some people want to wash their private parts by washing their feet. Little do they know that the mold of athlete's foot can be brought to the perineum and can easily cause tinea cruris. Do not use a towel to wipe your lower body to wipe your feet. You should prepare a separate towel for wiping your private parts. After wiping, wash it with clean water and dry it for later use.
