Phimosis is a condition where it is difficult to retract the foreskin over the tip of the penis. This may be caused by the opening of the foreskin of the penis being too small, or the foreskin being too tight or stuck to the head of the penis.

The foreskin is connected to a newborn’s penis at birth. This called physiologic phimosis. As a child grows, the foreskin naturally separates from the head of the penis. In some boys, the foreskin does not separate. The reason why is not known.
In other cases, called pathologic phimosis, it may happen due to:
- Repeated forceful retraction of the foreskin
- Inflammation and swelling
Phimosis is more common in young boys. It may also occur in older boys and men.
Risk factors for phimosis may include:
- Bacterial infections such as balanitis
- Poor hygiene
You will be asked about your symptoms and medical history. A physical exam will be done. It will include a genital exam. The diagnosis is made based on the ability of the foreskin to retract.
Phimosis may improve with time. If treatment is needed it will be chosen depending on the cause of your phimosis. Talk with your doctor about the best treatment plan for you.
Your doctor may advise medication that is applied to the area. Medication can help decrease swelling and loosen the skin.
If medication is not successful, a surgical procedure may be done. The foreskin may need to be partially or totally removed. This can be done with circumcision. Occasionally, small strands connecting the foreskin to the penis, called adhesions, can be removed.
There are ways to reduce your chances of getting phimosis. These may include:
- When able to do so, gently retract the foreskin when urinating and bathing
- Maintain good hygiene of the penis and foreskin
- Circumcision to remove the foreskin
