What is this black stuff on my penis?

Generally speaking, the epidermis of a man's penis is very smooth, which may be related to the pigment in the body. Therefore, some men's penises are the same color as their skin, while others are much darker than their skin. In daily life, some male friends find black spots on their penises, just like spots on their faces. So, what are the black things on the penis?

Black spots on the glans penis are local pigmentation. If there is masturbation or sexual intercourse before the onset of the disease, the black spots on the glans penis should be considered as the possibility of superficial venous embolism of the penis. Superficial venous embolism of the penis refers to the small veins visible under the skin of the penis, which become tortuous and dilated due to thrombosis, and the symptoms and signs appear.

Generally speaking, if you have a long-term masturbation habit or do not pay attention to hygiene, and never wash for a long time, it may cause black to appear. If accompanied by pain, you can go to the hospital to check whether there are other complications. If everything is normal, no treatment is needed.

The cause of pigmentation is usually the stimulation of sunlight, ultraviolet radiation or cosmetics, drugs and other substances, which form black skin pigmentation. Part of it falls off with the stratum corneum, while part of it settles in the basal layer and is discharged from the body through blood circulation. Once the above functions are out of balance, pigmentation will be formed.

Internal factors

1. Endocrine disorders. Often, customers have serious facial problems such as spots and acne, and beauticians often attribute them to endocrine disorders.

2. Genetic factors. Generally speaking, facial pigmentation that appears before the age of 18 may be related to genetics.

External factors

1. Due to environmental and air pollution, holes in the ozone layer generate a large amount of ultraviolet rays that directly radiate our skin. In order to prevent skin cells from being oxidized, the human body secretes a large amount of melanin for protection, which leads to pigmentation and the formation of dark spots.

2. Food. The nutrition of our skin mainly comes from the blood. Whether the nutrients in the blood are sufficient and suitable for the survival of cells depends on the quality of food. Alkaline substances can neutralize the acidity of meat and grain foods, keep the body fluids in an alkaline environment, dissolve toxic substances precipitated in the cells, and excrete them with urine. It can also accelerate metabolism. Alkaline foods include: fresh fruits and vegetables, raw garlic, black fungus, kelp, etc.

3. The cleanliness of cosmetics and skin. Since cosmetics contain chemicals and heavy metals such as lead, improper cleaning can easily cause pigmentation.

4. Photosensitivity: Long-term sun exposure and strong radiation light sources will accelerate the synthesis of melanin, causing the skin to darken.

5. Special physiological and emotional factors: During menstruation and pregnancy (especially during pregnancy), due to the stimulation of progesterone, the secretion of the corpus luteum in women's body will increase, thus causing pigmentation or worsening of pigmentation.
