Seven cold knowledge about the lifeblood of men? Inventory of health knowledge about male private parts

The penis is simply the lifeblood of men, and cannot tolerate carelessness. A slight lack of attention may harm the health of the penis and even cause penile necrosis. There is not much knowledge about the penis that even men themselves know, so it's worth taking more time to learn about it.

What is the knowledge about the penis?

1. Regular erection is beneficial for penile health

After research, it has been found that the penis, like other parts of the body, maintains regular exercise. Penile erection is supported by congestion of the penis, and the smooth muscles of the penis maintain regular congestion, allowing the penis to receive sufficient blood and oxygen nourishment. After falling asleep at night, being stimulated by the brain can cause an erection of the penis. When the nerve center that controls the penis is damaged or suffers from "three highs" and diabetes, nerves and blood vessels will be damaged, resulting in difficulty in erecting the penis. Irregular erection of the penis or weakening of the elasticity of the penis tissue, resulting in a reduction of the length of the penis by 1-2 centimeters.

2. The penis is divided into dominant and recessive

There is no correlation between penile weakness and length after erection. Dominant penis refers to the absence of a significant increase in penis length after erection, while recessive penis refers to a significant increase in penis length after erection. After research, it was found that compared to men with longer penises in non erect conditions, men with shorter penises actually doubled their length after erection.

3. The most sensitive area is below the penis

The lower part of the glans and the lower part of the penis are the most sensitive to sexual pleasure, followed by the upper part of the glans and the side of the penis, and finally the upper part of the penis and foreskin.

4. After entering middle age, the sensitivity of the penis will decrease

The greatest decrease in penile sensitivity is observed in males between the ages of 65 and 75, but some males experience difficulty with erections around the age of 50, which is significantly different from when they were young.

5. Oscillator for penile tube use

When it comes to oscillators, people will think of female masturbation products, which are actually useful for men and can stimulate their penis. Especially for non ejaculation caused by spinal cord injury, the appropriate use of an oscillator can help with successful ejaculation. Because oscillators can stimulate the nervous system related to ejaculation below the penis, they are particularly suitable for men who have difficulty or difficulty achieving orgasm during ejaculation.

6. The penis is prone to harboring bacteria

There are too many bacteria hidden in the skin and foreskin of the penis. After research, it was found that there are actually 42 unique bacterial communities in the foreskin of the penis. However, after circumcision, the bacterial population carried by the penis will decrease. In addition, studies have shown that circumcision can reduce the risk of AIDS virus infection. So for the sake of their own and sexual partner's health, men need to pay attention to cleanliness and hygiene in their private areas. If there is foreskin too long or phimosis, they need to go to the hospital for surgery.
