Swollen Penis Symptoms

A normally functioning penis is important for urination, sexual activity, and fertility. Swelling of the penis can interfere with these functions and should be addressed. The size of the penis is impacted by drainage of lymphatic fluid and blood. Swelling may be a sign that drainage of one of these substances is not occurring as it should. The skin of the penis can also become swollen.

Characteristics

Symptoms that can be associated with a swollen penis depending on the underlying cause include:

Swollen Penis Causes Overview

Causes of a swollen penis are detailed in order from most to least common below. This swelling is likely due to excess fluid, injury, infection or skin conditions.

Excess fluid

Causes related to excess fluid in the penis may include the following.

  • Prolonged erection: In the conditionpriapism, the penis becomes erect without sexual stimulation and stays that way for hours at a time [1].The erection is typically painful. It is normal for blood to rush into the penis and cause an erection during sexual arousal, but priapism occurs when the extra blood becomes trapped in the penis. This can be a medical emergency.
  • Other local causesof excess fluid: If the foreskin is rolled back and becomes trapped, it forms a tight band preventing normal drainage of blood, resulting in swelling of the tip of the penis. Swelling can also occur when lymphatic fluid is trapped in the penis due to a congenital or acquired abnormality of the local drainage system [2].
  • Whole body fluid overload: Medical conditions that cause excess fluid throughout the entire body (edema), such as heart or kidney failure, can lead to swelling of the penis and scrotum.

Injury

An injury to the penis may lead to swelling, such as those below.

  • Fracture: An injury to an erect penis can rupture one of the chambers that normally fills up with blood to create an erection. A penis fracture leads to pain,bruising, swelling, and loss of the erection [3].
  • Friction: Swelling and discomfort of the penis after penetrative sexual intercourse, without other symptoms, may occur due to friction.

Infection

Swelling of the penis may be a sign of a sexually transmitted infection, such as chlamydia or gonorrhea. Other symptoms will be present, such as sores, redness, itching, or penile discharge. A swollen penis can also occur due to infections that are not transmitted sexually [4].

Skin conditions

Skin disorders can cause inflammation and swelling at the head of the penis. These include psoriasis and contact dermatitis, which can occur after use of latex condoms if you have a latex allergy [5]. Redness and itchiness may also be present.

Swollen Penis Treatments and Relief

Quick medical treatment is necessary for some conditions that cause a swollen penis to prevent permanent damage that could lead to scarring, loss of tissue, and/or erectile dysfunction.

At-home treatments

There are several at-home remedies you can try to alleviate your symptoms.

  • Pause sexual activity: If you notice swelling and discomfort after sexual intercourse, avoid sex until your symptoms resolve and try using lubricant to reduce friction.
  • Avoid latex: Try using non-latex condoms and see whether your symptoms improve.
  • Practice good hygiene: Wash your penis daily with warm water to help prevent inflammation and infections.
  • Stay away from irritants: Avoid using soaps, perfumes, and lotions on the penis, since they may lead to contact dermatitis.
  • Take warm baths: These can help reduce swelling and discomfort.

When to schedule an appointment

In some cases, even if emergency care isn't necessary, you may need evaluation and treatment. Make an appointment with your medical provider if:

  • You are at risk for an STI (had unprotected sex and/or a sexual partner was diagnosed with an STI).
  • You have noticed sores, bumps, or penile discharge.
  • You are having difficulty urinating.
  • You have swelling that is staying the same or getting worse.
  • Your penis is painful.
  • You also notice swelling in other parts of your body, like your legs or scrotum.

Medical treatments

Your medical provider may prescribe one or more of the following treatments, depending on the cause of your swollen penis:

  • Steroid cream: This can soothe contact dermatitis.
  • Antibiotic or antifungal treatment: This is for any infection.
  • Other skin medication: This can treat a skin condition such as psoriasis.
  • A diuretic medication: This will increase urination in order to get rid of extra fluid in the body associated with edema.
  • Circumcision: This canresolve recurrent inflammation and infection of the foreskin [6].
  • Compression and massage: This can help remove trapped lymphatic fluid, or referral for surgical management after other treatments are ineffective.

Seek emergency treatment for the following

You should seek treatment with delay if:

  • You have a painful, persistent erection (priapism).
  • Your foreskin becomes stuck after being retracted.
  • You experience pain, swelling, loss of erection, and/or bruising after an injury to the penis.
  • You have increasing swelling, redness, brown/dark discoloration, and/or fever. These symptoms may be signs of a severe bacterial infection.
  • You are unable to urinate.
