Swelling of the penis after masturbation?


Hello Doctor: I experienced an unusual situation while masturbating last night, as it took me significantly longer than usual to ejaculate (almost an hour).
About an hour after ejaculation, I noticed that my foreskin was swollen around the edge, but the area near the base of the penis appears normal.
What should I do? The swelling is currently not painful, but there is discomfort when I apply pressure to the affected area.

Erection occurs due to vascular engorgement; therefore, if the erection lasts too long, it may lead to edema.
Most cases can resolve on their own after rest, but the condition can vary among different patients.
It is important to note that a simple description cannot determine the medical condition.
A thorough consultation and medical history are necessary.
It is still recommended to seek evaluation and examination from a qualified physician.

More Info


Post-masturbation penile swelling can be a concerning experience, but it is often a benign condition that can be attributed to several factors. Understanding the causes of this swelling and potential solutions can help alleviate your concerns.


Causes of Penile Swelling After Masturbation
1. Increased Blood Flow: During sexual arousal and masturbation, blood flow to the penis increases significantly. This engorgement can lead to temporary swelling, especially if the activity is prolonged, as in your case where it lasted nearly an hour. The swelling is usually a result of the blood vessels expanding to accommodate increased blood flow.

2. Edema: Prolonged stimulation can lead to localized edema, which is the accumulation of fluid in the tissues. This can occur if there is excessive friction or pressure during masturbation, leading to irritation and swelling.

3. Irritation or Allergic Reaction: Sometimes, the materials used during masturbation (such as lubricants or condoms) can cause irritation or an allergic reaction, leading to swelling. If you used a new product, this could be a potential cause.

4. Injury or Trauma: If there was any vigorous or rough handling during masturbation, it could lead to minor trauma to the tissues, resulting in swelling. This is usually accompanied by some discomfort or pain, but not always.

5. Infection: Although less common, infections can cause swelling. If there are any signs of redness, warmth, or discharge, it may indicate an infection that requires medical attention.


Solutions and Recommendations
1. Rest and Recovery: If the swelling is mild and not accompanied by pain, the best course of action is often to allow your body to recover. Avoid further sexual activity until the swelling subsides.

2. Cold Compress: Applying a cold compress to the swollen area can help reduce swelling and provide relief from discomfort. Make sure to wrap ice in a cloth to avoid direct contact with the skin.

3. Hydration: Staying well-hydrated can help your body manage swelling more effectively. Drink plenty of water to support your overall health.

4. Avoid Irritants: If you suspect that a lubricant or other product may have caused the swelling, discontinue its use and consider switching to hypoallergenic options.

5. Monitor Symptoms: Keep an eye on the swelling. If it persists for more than a few days, worsens, or if you develop additional symptoms such as pain, redness, or discharge, it is important to seek medical attention.

6. Consult a Healthcare Provider: If you have ongoing concerns or if the swelling does not resolve, consult a healthcare provider. They can perform a physical examination and may recommend further tests if necessary.


When to Seek Immediate Medical Attention
- If you experience severe pain or discomfort.

- If there is significant redness, warmth, or discharge from the penis.

- If you develop fever or other systemic symptoms.

In conclusion, while post-masturbation swelling can be alarming, it is often a temporary condition resulting from increased blood flow or minor irritation. By following the recommendations above and monitoring your symptoms, you can manage the situation effectively. If in doubt, do not hesitate to reach out to a healthcare professional for personalized advice and reassurance.
