Phimosis (Tight Foreskin) – Symptoms of a Tight Foreskin and Treatment Options

Phimosis is a common condition affecting the penis. It is usually congenital, but in rare cases it can also develop later in life.

In this condition, there is a mismatch between the stretchable width of the foreskin and the diameter of the glans. The foreskin is too tight, and because of this mismatch, it cannot be retracted over the glans at all, or can only be done so with pain.

Such pathological phimosis must be distinguished from the natural narrowing of the foreskin. This is perfectly normal in newborn boys as well as in infants and toddlers.

Only if this congenital narrowing of the foreskin persists beyond the age of five is it considered a pathological condition, which can be treated with medication under certain circumstances or, in other cases, with phimosis surgery.

Foreskin constriction can be divided into various forms, such as:

• incomplete relative and complete phimosis, and
• primary (congenital) and secondary (acquired) phimosis.

Relative incomplete phimosis occurs when the foreskin cannot be retracted only when the penis is erect. In complete phimosis, however, it is not possible to retract the foreskin even when the penis is flaccid.

Primary phimosis is congenital. Foreskin narrowing and adhesion between the foreskin and the glans are very common in newborn boys and young children. This type of physiological phimosis usually resolves on its own within the first two years of life. Generally, the doctor does not recommend surgery for phimosis.

If the foreskin cannot be retracted over the glans after the age of five, this indicates primary phimosis. Secondary phimosis develops later in life.

96 percent of all newborn boys are born with phimosis.

By age seven, about 18 percent of all boys are affected by phimosis. In the 16- to 18-year-old age group, the figure drops to just 1 percent.

Phimosis is caused by a congenital or acquired narrowing of the outer ring of the foreskin.

Secondary phimosis is usually caused by recurrent inflammation of the foreskin (posthitis) or inflammation of the glans (balanitis). These conditions lead to scarring and, consequently, shrinkage of the foreskin.

Violent impacts, including

• injuries,
• bleeding, or
• tears in the foreskin,

that heal with scarring can also cause acquired phimosis.

Other possible causes of acquired phimosis include

• certain skin conditions, such as lichen sclerosus, as well as
• a shortening of the frenulum—the band of skin on the underside of the penis.

Under certain circumstances, normal phimosis in early childhood can also develop into secondary phimosis. For example, if parents try to forcefully retract the foreskin of their young son. This can cause tears in the mucous membrane and scarring due to inflammation. As a result, pathological phimosis may develop, which in many cases can only be corrected through surgery.

Those affected cannot retract their foreskin completely over the glans, or can do so only with pain.

For this reason, they are only able to maintain genital hygiene to a very limited extent. As a result,

• sebum,
• secretions such as urine and semen residues, as well as
• cellular components

. These form whitish deposits known as smegma. It can cause inflammation of the glans and foreskin. This leads to chronic inflammation, which also increases the risk of penile cancer.

In some cases, urine cannot flow freely due to the narrowing of the foreskin. This can lead to discomfort during urination (micturition). The result is urinary dysfunction, which usually manifests as a

• thin, weak, or strongly deflected urine stream, as well as
• a balloon-like swelling of the foreskin during urination.

This, in turn, can lead to inflammation in the genital area and recurrent urinary tract infections. Other possible symptoms include pain during erections and sexual intercourse. In some cases, sexual intercourse is only possible to a limited extent or not at all. During an erection, a feeling of tightness or tears in the foreskin may occur.

Phimosis is usually diagnosed through a physical examination and a discussion of the patient’s medical history with a urologist. The specialist may recommend phimosis surgery if necessary.

During the physical examination, the treating physician usually identifies phimosis based on the typical symptoms. Phimosis can be clearly recognized by the fact that

• the foreskin cannot be retracted over the glans, or can only be partially retracted, or
• a constricting ring becomes visible when the foreskin is retracted over the glans.

During the medical history interview, the specialist will ask about other typical findings and symptoms. Previous inflammation of the foreskin or glans is also relevant to the diagnosis.

To treat phimosis, the constricted foreskin is either widened or removed. This can be done surgically, such as through circumcision, or conservatively using cortisone ointments.

Conservative therapy is only possible in cases of mild phimosis. Therefore, surgery is necessary in most cases.

Procedure for cortisone therapy

The cortisone ointments must be applied to the constricted foreskin twice daily over a period of four to eight weeks.

About two weeks after starting this conservative treatment, you can begin to gently pull back the foreskin as far as possible. This allows the foreskin to gradually stretch and widen. It is absolutely essential to avoid tearing the foreskin during this process. In about 50 to 75 percent of cases, treatment with the ointment is successful.

However, if the foreskin becomes trapped behind the glans and constricts it, this is known as paraphimosis. This constitutes a urological emergency that must be treated immediately; otherwise, in the worst-case scenario, it can lead to necrosis of the glans. 

In the case of paraphimosis, the specialist first attempts to carefully retract the foreskin by hand under local anesthesia. If this is unsuccessful, phimosis surgery is also necessary.

The standard procedure is circumcision, which involves the complete surgical removal of the foreskin.

Circumcision

In adults, circumcision is performed under local anesthesia and usually takes only about 30 minutes. In children, the procedure is performed under general anesthesia.

During phimosis surgery, the urologist surgically removes the entire foreskin. In rare cases, only the anterior constriction (partial circumcision) can be removed. 

Afterward, the incision is sutured in both methods. In the first few days following the procedure, pain medication prescribed by the doctor alleviates any discomfort. Careful wound care is required after the operation to prevent infection.

The sutures dissolve on their own within about two weeks. The treating physician will conduct follow-up examinations.

Circumcision has been a routine procedure for many years and is performed on an outpatient basis in most cases; under certain conditions, it may also be performed on an inpatient basis. Many years of experience with phimosis surgery have shown that complications and serious side effects, such as postoperative bleeding, are rare.

Circumcision Without a Medical Indication

If surgery is performed as part of phimosis treatment, health insurance companies cover the costs. However, if you decide to have yourself or your child circumcised for religious or aesthetic reasons and without a medical indication, you must cover the costs privately.

Frenulotomy

In addition to circumcision, other surgical methods are also available. If the phimosis is caused by a shortened frenulum (frenulum breve), a frenulotomy may be an option. This procedure involves cutting the frenulum.

In this case, the entire foreskin is not removed; instead, a simple incision is made to cut the too-short frenulum, which is then sutured lengthwise. Afterward, the typical pain associated with an erection should no longer occur.

What is phimosis?

Phimosis is a narrowing of the foreskin in which the foreskin cannot be retracted over the glans. This natural or physiological phimosis is particularly common in infants and young children. The adhesion between the foreskin and the glans usually resolves completely by the end of puberty.

What symptoms does a tight foreskin cause?

Typical symptoms of phimosis include pain during urination, a constricted foreskin, or discomfort during an erection. Some affected individuals have a sensitive glans or inflammation of the glans. In cases of paraphimosis, the foreskin remains pulled back behind the glans and constricts the penis like a “Spanish collar.”

How is phimosis treated?

Treatment for phimosis depends on the type of foreskin constriction and may be conservative or surgical. A cortisone-based ointment combined with careful retraction of the foreskin often helps. If the foreskin cannot be retracted over the glans or if scarring is present, surgical treatment involving circumcision may be necessary.

When is surgery necessary for phimosis?

Phimosis requires treatment if it causes severe discomfort, inflammation, or problems with urination. Acquired phimosis caused by lichen sclerosus or repeated scarring may also necessitate surgical intervention. The goal of the surgery is to permanently widen the foreskin of the penis or to partially remove it.

What should be avoided in cases of phimosis?

The foreskin should never be forcibly retracted. Forcibly retracting the foreskin can lead to injury, adhesions, or paraphimosis. Instead, the foreskin should be handled with care, and if symptoms occur, a medical examination should be sought.
