The glans and coronal sulcus after masturbation?


Hello doctor, after masturbating yesterday, I noticed a reddish area on the right side of the glans in the morning, specifically around the coronal sulcus.
Upon closer inspection, it appears to be mostly microvessels.
I'm wondering if friction could cause these microvessels to rupture, as it looks like redness from within the skin layers.
Should I go to the hospital for an examination?

Hello: If there is no broken skin, you can keep the area clean and dry and observe if it resolves on its own.
If there is broken skin, it is important to seek medical attention.
Wishing you good health.

More Info


When it comes to experiencing redness in the coronal sulcus after masturbation, it is important to understand the potential causes and when to seek medical help. The coronal sulcus is the groove that separates the glans (head) of the penis from the shaft, and redness in this area can be concerning for several reasons.

Firstly, the redness you are observing could indeed be a result of friction or irritation during masturbation. This is not uncommon, especially if there was vigorous activity or if lubrication was insufficient. The microvascular damage you mentioned, where small blood vessels may break due to excessive friction, can lead to localized redness and swelling. This condition is often self-limiting and may resolve on its own with time and proper care.

However, there are other potential causes for redness in this area that should be considered. These include:
1. Infections: Conditions such as balanitis (inflammation of the glans) or sexually transmitted infections (STIs) can cause redness, swelling, and discomfort. If there are accompanying symptoms such as discharge, pain, or itching, it is crucial to seek medical attention.

2. Allergic Reactions: Sometimes, the use of certain lubricants, soaps, or other products can lead to allergic reactions, resulting in redness and irritation.

3. Dermatological Conditions: Skin conditions such as psoriasis or eczema can also affect the genital area, leading to redness and irritation.

4. Trauma: If there was any trauma during masturbation, such as excessive force or the use of foreign objects, this could lead to localized redness and swelling.

Given these considerations, here are some guidelines on when to seek medical help:
- Persistent Symptoms: If the redness does not improve within a few days or worsens, it is advisable to consult a healthcare professional.

- Accompanying Symptoms: If you experience additional symptoms such as pain, swelling, discharge, or fever, you should seek medical attention promptly.

- Concerns About STIs: If there is any possibility of exposure to STIs, or if you have had unprotected sexual contact, it is important to get tested and evaluated by a healthcare provider.

In the absence of severe symptoms or persistent redness, you may choose to monitor the situation for a few days. Applying a gentle, fragrance-free moisturizer or a barrier cream can help soothe the area. Avoiding further irritation, such as tight clothing or additional friction, is also advisable.

In summary, while mild redness in the coronal sulcus after masturbation may not be a cause for alarm, it is essential to remain vigilant for any changes or worsening of symptoms. If you have any doubts or concerns, it is always best to err on the side of caution and consult a healthcare professional for a thorough evaluation and appropriate management.
