Excuse me, how is the urethral orifice black?

The color of the urethral orifice is normal. Under normal circumstances, the color of the male urethral orifice is slightly redder than the penis head, and its red range does not exceed the outer edge of the urethral orifice. It is naturally closed without swelling, secretion and pain. The surface layer of male urethral orifice is mucous membrane, and its capillaries are very rich. There are urethral glands in the anterior urethra, and many glandular ducts open to the urethral mucosa, which can secrete colorless and transparent mucus and keep the urethral orifice moist.

First, local and environmental factors lead to the blackening of urethral orifice.

The dark purple of urethral orifice may be caused by local pigmentation and superficial penile vein embolism. Because the color of urethral orifice is easily influenced by blood circulation, local and environmental factors, such as high temperature weather, sitz bath, strenuous exercise, etc., it can all cause the urethral orifice to be black. Wearing clothes too tightly in winter will also cause blood blockage of local capillaries at the tip of glans penis, so it looks slightly black. As long as you wear loose clothes and pay attention to local hygiene, it will be absorbed slowly.

Second, stimulate the foreskin to be too long or phimosis to cause the urethral orifice to be black.

Because the foreskin is too long or the stimulation of phimosis can lead to black and purple urethral orifice, but patients often have no other discomfort and no secretion at the urethral orifice. Some people often suffer from balanitis prepuce. At this time, you can see that the glans penis has little red dot of different sizes, which is wet and itchy locally. For the above situation, it is suggested to remove the long foreskin or phimosis and keep the exposed penis head dry.

Three, gonorrhea, nongonococcal urethritis and other sexually transmitted diseases caused by urethral orifice blackening.

The main symptoms of gonorrhea, non-gonorrhea and other sexually transmitted diseases are abnormal symptoms of urethral orifice, such as urethral tingling, increased secretion, redness and pus discharge. In severe cases, it will also lead to the blackening of the urethral orifice. For those who have unclean sex, if the urethral orifice is found to be black and purple, they should go to a specialist in a regular hospital for a definite diagnosis and regular treatment.
