Black Spots on Glans After Ejaculation: Causes and Concerns - Urology

Share to:

During ejaculation, there is a tight grip on the penis, and dark spots appear on the glans?


Hello doctor, during sexual intercourse with my girlfriend, I held the tip of my penis near the glans tightly to prevent ejaculation for about two to three minutes.
When I went to the bathroom, I noticed black spots on the glans, resembling bruises, and I experienced a stinging sensation while urinating.
I would like to ask if this is normal and if it will go away after a while.
Thank you.

It is recommended to visit a clinic for a physician's examination.
Online consultations cannot replace an in-person assessment and physical examination by a doctor.
If there is a medical condition, it is still advised to seek care at a healthcare facility.

More Info


The appearance of black spots on the glans after ejaculation, especially following a period of intense pressure applied to the penis, can be concerning and may indicate several underlying issues. Based on your description, it seems that the black spots resemble bruises, which could be a result of trauma to the delicate tissues of the glans. When excessive pressure is applied, particularly during sexual activity, it can cause small blood vessels to rupture, leading to localized bleeding and the formation of bruises. This is often referred to as a "petechial" or "purpuric" rash, which can appear as small red or black spots.

In addition to the bruising, the pain you experience during urination could be attributed to irritation or inflammation of the tissues in the area. This could be due to the trauma sustained during the act of holding the penis tightly, which may have caused micro-tears or irritation of the skin and underlying tissues. It is also possible that the pressure applied could have affected the urethra, leading to discomfort during urination.

While it is common for such bruising to resolve on its own over time, it is essential to monitor the situation closely. Here are some considerations and recommendations:
1. Observation: If the black spots do not improve or begin to spread, or if you notice any additional symptoms such as increased pain, swelling, or discharge, it is crucial to seek medical attention. These could be signs of a more serious condition, such as an infection or a more significant injury.

2. Rest and Avoidance: It may be advisable to avoid any further sexual activity or manipulation of the area until the symptoms have resolved. This will help prevent further irritation or injury.

3. Pain Management: Over-the-counter pain relief medications, such as ibuprofen or acetaminophen, can help manage discomfort. However, ensure you follow the recommended dosages and consult with a healthcare provider if you have any underlying health conditions or are taking other medications.

4. Hydration and Hygiene: Ensure you are well-hydrated and maintain good hygiene practices. This can help support healing and prevent any potential infections.

5. Consultation with a Healthcare Provider: If the symptoms persist beyond a few days, or if you have any concerns about the appearance of the spots or the pain during urination, it is advisable to consult a healthcare provider. A urologist or primary care physician can perform a thorough examination and may recommend further testing, such as a urinalysis, to rule out any infections or other underlying conditions.

In summary, while the black spots on the glans may be a result of trauma from the pressure applied during ejaculation, it is essential to monitor the situation closely. If symptoms do not improve or worsen, seeking medical advice is crucial to ensure proper diagnosis and treatment. Remember that sexual health is an important aspect of overall well-being, and addressing any concerns promptly can help maintain both physical and emotional health.
