Penile venous engorgement


Hello Doctor, about two weeks ago, I engaged in oral sex, and since then, I have noticed two or three prominent veins on my penis (which I found online should be the dorsal superficial veins of the penis).
Occasionally, there is mild pain when I apply slight pressure, and I can see a network of veins beneath the skin of my penis.
Currently, one of the veins has disappeared, another has become slightly less prominent but is still slightly raised, and the last one is mostly visible but sometimes the symptoms diminish or disappear.
Additionally, I have recently noticed that the color of the glans has slightly whitened, and I am concerned that this might be due to poor blood circulation in the penis.
Is this condition likely to resolve on its own, or should I see a doctor?
Furthermore, after the oral sex, I experienced nocturia about two to three times each night, which decreased significantly after four to five days.
However, now I occasionally feel mild pain when I gently press on the urethra.
Could this indicate an infection or inflammation? Thank you for your guidance, Doctor!

Hello: You should seek consultation from the urology department at the hospital.
Currently, avoid oily foods, and maintain cleanliness and dryness.
Additionally, if you experience symptoms after oral sex, a urine test should be performed.
Wishing you good health.

More Info


Understanding penile vein distension can be quite concerning, especially when accompanied by changes in color and discomfort. Based on your description, it seems you are experiencing some vascular changes in the penile area following oral sexual activity. Let’s break down the potential causes, symptoms, and when you should seek medical help.


Causes of Penile Vein Distension
1. Increased Blood Flow: Engaging in sexual activity, including oral sex, can lead to increased blood flow to the penis, which may cause the veins to become more prominent. This is typically a normal physiological response.

2. Trauma or Injury: Sometimes, vigorous sexual activity can lead to minor trauma or injury to the blood vessels, resulting in localized swelling or distension. This could explain the appearance of new veins and any associated discomfort.

3. Inflammation: If there is any irritation or inflammation in the area, it could lead to changes in the appearance of the veins. This might also explain the slight pain you feel when pressing on the area.

4. Vascular Conditions: In rare cases, underlying vascular conditions could cause changes in the veins. However, this is less likely if the changes appeared suddenly after a specific event.


Symptoms to Monitor
- Pain: Mild pain upon pressing is not uncommon, but if it becomes severe or persistent, it warrants further investigation.

- Color Changes: The whitening of the glans (tip of the penis) could indicate reduced blood flow or other issues. If this persists or worsens, it is essential to seek medical advice.

- Urinary Symptoms: The occurrence of nocturia (nighttime urination) and mild pain when pressing on the urethra could suggest a urinary tract infection (UTI) or inflammation.

When to Seek Help
- Persistent Symptoms: If the distension of the veins does not resolve within a few days or worsens, it is advisable to consult a healthcare professional.

- Severe Pain: If you experience significant pain, especially if it interferes with daily activities or sexual function, you should seek medical attention.

- Color Changes: If the glans remains discolored or if you notice any other unusual changes, such as lesions or discharge, it is crucial to get evaluated.

- Urinary Issues: If you experience persistent pain during urination, changes in urine color, or any signs of infection (such as fever or chills), you should see a doctor promptly.


Conclusion
In many cases, penile vein distension following sexual activity can be a temporary condition that resolves on its own. However, given your symptoms, particularly the changes in color and urinary discomfort, it is wise to err on the side of caution. Consulting a healthcare provider, preferably a urologist, can provide you with a thorough evaluation and peace of mind. They may perform a physical examination and possibly recommend imaging studies or lab tests to rule out any underlying conditions.

Remember, sexual health is an important aspect of overall well-being, and seeking help is a proactive step towards maintaining it.
