Itching around the penis

Itching around the penis

If the penis is itchy, it is likely to be caused by fungal infection or allergy. Unhealthy sexual intercourse can lead to penis infection, so you must pay attention to the safety and hygiene of sexual intercourse, and it is best to use condoms during sexual intercourse. It may also be an inflammation caused by the accumulation of dirt due to excessive foreskin. In this case, you should not only pay attention to the cleaning and hygiene of the penis, but also choose to go to the hospital for circumcision.

1. Contact dermatitis: A small number of men with allergic constitutions may develop dermatitis reactions such as erythema and papules on the skin in contact with the underwear, which is made of chemical fiber raw materials. This may cause itching due to the close contact between the underwear and the perineum skin, which is easily soaked by sweat.

2. Balanitis: Men with excessive foreskin or phimosis often have chronic inflammatory reactions due to the accumulation of smegma in the coronal sulcus of the foreskin. They are also prone to condyloma acuminatum, which often causes local itching. The smegma should be cleaned frequently and removed in time, and circumcision should be performed if necessary.

3. Pubic lice: Pubic lice have special hook-shaped claws that grab the skin in the pubic hair area and the hair around the anus. Their bites and saliva toxins can cause local skin itching, folliculitis, and eczema-like changes.

4. Tinea cruris and tinea glutealis: Men with obese and sweaty physiques are prone to fungal growth and proliferation due to their sweaty and moist vulva, which can lead to tinea cruris and tinea glutealis. The symptoms are ring-shaped red papules on the thigh root or buttocks, which often have scaling and itching.

5. Scrotal eczema: The main manifestations are scrotal skin flushing, swelling or exudate desquamation. Due to severe itching, the scrotal skin may thicken and become lichenified after scratching. It is recommended that you go to the hospital for treatment to clarify the cause and receive treatment under the guidance of a doctor.

If the skin around the glans penis itches, there are three reasons to consider:

1. Infection

It is often caused by unclean sexual intercourse, infection with Candida albicans, Trichomonas, Chlamydia, Mycoplasma, Gonorrhea or other bacteria.

2. Non-infectious factors

Most of them are caused by excessive foreskin and insufficient cleaning, which leads to the accumulation of dirt between the foreskin and the glans penis, namely smegma, which irritates the local foreskin and mucous membrane and causes inflammation.

3. Balanitis

It manifests as erythema on the glans penis, and there are usually small pustules or papules on the surface. It also manifests as local edema of the glans penis mucosa, mild desquamation at the edges, and papules and pustules expand to the surrounding area to form glans penis erosion.

Common clinical manifestations include

1. Acute superficial balanitis

Initially, there is local flushing, redness and swelling of the penis skin, and a burning and itching sensation on the glans penis. When the foreskin is turned back, the inner surface of the foreskin and the glans penis can be seen to be congested and eroded, with exudate and even bleeding. After secondary infection, small ulcers can be seen, with a foul-smelling milky white purulent secretion. It is painful when rubbed against underwear, and patients often have difficulty in moving and itching of the glans penis. It may be accompanied by enlargement and tenderness of the inguinal lymph nodes.

2. Circumflex balanoposthitis

On the glans penis and foreskin, erythema can be seen, which gradually expands and becomes ring-shaped, and may form a superficial ulcer surface.

3. Candida albicans balanitis

Erythema can be seen on the foreskin and glans penis. The surface is smooth and there are small blisters. The edges of the erythema are clear. In acute attacks, there are erosions and exudates.

4. Trichomonas balanoposthitis

Papules and erythema appear on the glans penis, gradually expanding with clear edges. Needle-sized blisters can be seen on the erythema, and finally an erosive surface is formed.
