Phimosis: True vs. False and the Need for Circumcision - Urology

Before erection and after erection?


If the foreskin can be retracted before an erection but becomes more difficult to retract during an erection, although it can sometimes still be pulled back, is this considered true phimosis or false phimosis? Is circumcision necessary in this case?

Hello: It is more difficult to retract after an erection, but sometimes it can still be retracted.
If there is a feeling of tightness during sexual intercourse, surgery is recommended, as excessive tightness can cause discomfort (pulling sensation and poor circulation).
Thank you for your inquiry.

Phimosis is a condition where the foreskin cannot be easily retracted over the glans (the head of the penis). It can be classified into two types: true phimosis and false (or physiological) phimosis. Understanding the distinction between these two types is crucial for determining whether circumcision or other interventions are necessary.

True Phimosis: This condition is characterized by a tight foreskin that cannot be retracted at all, even when the penis is not erect. True phimosis is often associated with scarring or other anatomical issues that prevent the foreskin from being pulled back. It can lead to complications such as pain during erections, difficulty with hygiene, and increased risk of infections.

False (Physiological) Phimosis: This is a more common condition, especially in younger males, where the foreskin may be difficult to retract when the penis is erect but can be retracted when it is flaccid. In many cases, this type of phimosis is normal and can resolve on its own as the individual matures. It is important to note that physiological phimosis does not typically cause pain or other complications.

In your case, if you can retract the foreskin before an erection but find it more challenging during an erection, this suggests that you may be experiencing false phimosis. This is not uncommon and may not require surgical intervention. Many healthcare professionals recommend conservative management, such as gentle stretching exercises or topical corticosteroids, to help ease the retraction of the foreskin over time.

Need for Circumcision: Circumcision is not always necessary for individuals with phimosis. The decision to circumcise should be based on several factors, including:
1. Symptoms: If you experience pain, recurrent infections, or significant difficulty with hygiene due to the phimosis, circumcision may be recommended.


2. Age: In younger males, especially infants and children, it is often advisable to wait and see if the condition resolves on its own as they grow older.

3. Personal Preference: Some individuals may choose circumcision for cultural, religious, or personal reasons, even if they do not have significant symptoms.

4. Medical Advice: Consulting with a urologist or healthcare provider is essential. They can provide a thorough examination and discuss the potential benefits and risks of circumcision versus conservative management.

In conclusion, based on your description, it seems you may have false phimosis, which typically does not require circumcision unless it leads to complications or significant discomfort. It is advisable to monitor the situation and consult with a healthcare provider for personalized advice and management options. They may suggest non-invasive treatments before considering any surgical options.
