Where is the male coronal groove located?

The male coronal sulcus is located at the front end of the penis and the back end of the glans. When the foreskin retracts, the front end of the foreskin will wrap around the coronal sulcus. Therefore, if the foreskin is too long, it often causes redness and swelling in the coronal sulcus, causing inflammation, and easily forming smegma, which has a greater impact on the health of men's private parts and can easily lead to balanitis. Let's take a look at this aspect.

What is the coronal sulcus?

Located just behind the glans. The coronal sulcus refers to a circle where the glans and penis are connected. It is prone to inflammation, and smegma is easily accumulated when the foreskin is too long. The coronal sulcus, the common name for the neck of the penis, is a circle of groove-like structure at the lower edge of the glans of the male penis. When the foreskin is turned over, you can see that the ring-shaped contraction behind the glans is called the coronal sulcus. It is formed at the base of the glans when the front end of the urethral corpus cavernosum swells into the glans. It is a very sensitive part of the penis. Orgasm and ejaculation can occur by stimulating this area through sex or masturbation. The normal color is red with a slight purple tint.

What to do if the inflammation caused by foreskin and phimosis occurs?

Inflammation of the glans penis and foreskin often occur at the same time, so they are collectively referred to as glans penis phimitis (foreskin glans inflammation). As the name suggests, glans penis phimitis is a disease caused by the simultaneous infection of the glans penis and foreskin. The main cause of glans penis phimosis is phimosis or excessive foreskin. In addition, unclean sexual intercourse, drug stimulation or allergy are also causes of the disease. Generally, when the infection occurs acutely, there is often moisture, redness, swelling, pain, itching, and even erosion and shallow ulcers in the local area, and yellow purulent or milky white smelly secretions appear, accompanied by a special odor. In severe cases, glans penis necrosis may occur. After an acute attack, the infection will cause the foreskin to adhere to the glans penis, the foreskin cannot be turned up, and even cause urethral stenosis. Some patients develop urethral adhesion and stenosis after the acute phase, causing difficulty in urination. Repeated infection can cause thickening of the glans penis or foreskin, forming white spots.

When taking certain drugs, allergic reactions may sometimes cause fixed edematous erythema to form on the glans penis or foreskin, with blisters in the center that can cause infection after rupture. Symptoms usually occur within 24-36 hours after taking the drug, improve after stopping the drug, and reappear after taking the drug again.

The treatment of acute attacks is to turn the foreskin up or cut the back of the foreskin to facilitate drainage, and use 1:5000 potassium permanganate solution for local washing, or apply antibiotic ointment, such as chlortetracycline ointment. And use antibacterial drugs (antibiotics) for the whole body, such as penicillin injection, 800,000 units each time, 2 to 3 times a day. After the acute attack period, you should go to the hospital for circumcision. If the urethra is narrow, plastic surgery is also required. If it is caused by drug allergy, anti-allergic drugs should also be taken.

It is very common for the foreskin to be too long and foreskin to recur. When taking a bath, the foreskin should be turned over to clean the smegma in the foreskin sac. This is the simplest and most effective way to prevent inflammation. Chronic irritation of smegma and recurrent smegma are also important factors causing penile cancer. Therefore, early circumcision is of certain significance in preventing penile cancer.
