What is the cause of the black and purple glans?

Under normal circumstances, if there is no disease on the male glans, it should be pink, and the glans is wrapped in the male foreskin all year round, so its surface is very smooth. However, some male glans may also become diseased, for example, some men may find that their glans is black and purple. Let's take a look at what is the black and purple glans?

As long as there is no pain, itching or other discomfort, it is normal. You should know that the color of the glans is originally dark red, especially the edge of the glans. Because of the rich nerve endings and blood supply, coupled with frequent friction, the edge of the glans becomes darker during erection, which is a very normal phenomenon. If the root of the glans is purple as you described, that is, the edge of the glans becomes darker red with a little purple-red, there should be no problem.

Of course, if in addition to color changes there are also symptoms such as mild itching and rashes, then consider inflammatory factors. If you do not pay attention to genital hygiene and have a foreskin that is too long, you can consider that this is a symptom of balanitis.

Suggestions: If the area around the glans penis turns purple or black, it is recommended that you pay attention to hygiene, wash your genitals every day, wear loose, breathable underwear and change it frequently, eat a light diet with less spicy food, have a normal and regular sex life, neither indulge in nor abstain from sex, and urinate in time after sex to flush out the semen remaining in the urethra to prevent urinary tract inflammation.

The glans penis is rich in blood vessels, and most of the surface is veins, which makes the color darker. The glans penis swells after erection, and shrinks in size after returning to normal, resulting in some wrinkles on the surface.

This is a normal physiological phenomenon. As long as there is no abnormal discharge, no pain, and no swelling, it is fine. Pay more attention to cleanliness and clean the smegma.
