What causes the penis to turn black?

When male friends are young, they are basically taken to the hospital for circumcision in order to allow the penis to develop better. As a normal male, the color of the penis should be flesh-pink, but some people's penises will turn black, which causes these people to suspect that they have some disease. However, there are many reasons for the blackening of the penis. Let's take a look at why the male penis turns black.

First of all, in terms of congenital factors: pigmentation will only appear in the genitals after entering puberty. All these phenomena are due to the long-term stimulation of sex hormones in these areas, which causes a large amount of melanin deposition and makes the skin color become very dark. No wonder some people say that the color of genital skin is a "display" of sex hormones.

Secondly, in terms of acquired factors: frequent and regular sex can make you produce more sex hormones. At the same time, coupled with long-term and frequent congestion and friction of the penis, this will of course make your penis continue to become deeper on the original basis.

As for what you said, "some people's hair is still white even at the age of thirteen (boys with a lot of pubic hair)", he is only 13 years old, just entered puberty, and has not had any sexual stimulation, so of course the color will be very light, which is normal. This will not turn black until there is frequent sexual stimulation in the late development period around the age of 20. In addition, this also has a lot to do with your skin color. People with naturally dark skin will have darker skin.

1. Masturbation for a long time

If you masturbate for a long time or have a lot of sexual experience, the penis will become very dark due to frequent friction and melanin deposition.

2. Prolonged erection and congestion

The blackening of the male glans may be caused by prolonged erection and congestion. In this case, male friends need to arrange their sex life reasonably and have sex in moderation to avoid the occurrence of other male diseases.

3. Disease factors

For example, balanitis may cause the male glans to turn black, which is mainly caused by bacterial infection of the glans and long-term inflammatory stimulation.

4. Drug stimulation

The blackening of the glans may also be caused by medication. The long-term stimulation of the drugs causes the glans to turn black.
