What is Phimosis?
Phimosis is the medical word that describes a tight foreskin that cannot be pulled back past the head of the penis (glans).
This is normal in babies and infants (physiologic phimosis), as almost all boys under 2 years of age have a tight foreskin at birth that cannot be pulled back to expose the head. Through repeated erections and developmental changes, the foreskin generally loosens through the ages of 3-16 so that by the age of 16-18, only 1% of boys will still have phimosis (pathologic phimosis).
What causes Phimosis?
One cause of pathologic phimosis is overzealous and forceful pulling back of the foreskin in young children, which can cause adhesions and scarring that leads to the tightness. The foreskin should never be forcibly pulled back as it can also lead to paraphimosis (a medical emergency that occurs when the foreskin has been pulled back, but then cannot be replaced over the head).
How common is phimosis?
It’s very common in young children, but much less common in adults. Nearly every newborn boy has a foreskin that won’t retract- that’s normal anatomy. It loosens through childhood and adolescence, so that by 16 to 17 only about 1% still have a truly tight foreskin.
In adult men, phimosis affects roughly 1 to 2 in 100. It’s common enough that any GP will have treated it many times, and it’s one of those conditions men tend to assume is rarer than it is, because people tend not to talk about it.
What are the symptoms of Phimosis?
Phimosis can lead to symptoms like painful erections, ballooned foreskin while urinating, blood in the urine, cracked and fissured skin around the foreskin and recurrent urinary tract infections. Further, it can lead to psychological harm particularly when it also impedes sexual function and relationships.
One of most common symptoms is difficulty to fully clean under the foreskin where smegma (white secretions) can persist, leading to foul smell and increased likelihood of infection.
Some studies have found an increased incidence of penile cancer in men with phimosis, possibly in relation to difficulty cleaning leading to poorer hygiene and higher rates of HPV (human papilloma virus) infection.
Is a tight foreskin normal for teenage boys?
A tight foreskin is completely normal in childhood and usually sorts itself out on its own. Almost all boys are born unable to pull their foreskin back- it loosens gradually over the years. By around 10, many boys still can’t retract it fully. That is not a problem and does not need fixing.
By 15 or 16, roughly 1 in 100 boys still have a genuinely tight foreskin, but it’s still possible for it to loosen on its own over the next couple of years.
By 18, it is much less likely to resolve by itself, and it is worth speaking to a GP, as there may be some straightforward treatment options such as topical creams.
It’s advisable to see a doctor sooner rather than later if the foreskin balloons when you pee, if it’s sore, splitting or getting infections, or if it’s tight enough to make erections painful. Doctors see this relatively frequently, and it can be a straightforward issue to treat.
One thing not to do: don’t force it back. Forcing a tight foreskin tears the skin, and tearing heals as scar tissue that is tighter than what you started with. If you do pull it back, always slide it forward again straight away.
Can men develop Phimosis later in life?
Quite apart from ongoing phimosis from childhood, phimosis can develop at any age and after many years of a normally retracting foreskin. This can be a sign of an underlying condition such as:
- Lichen sclerosus (an autoimmune condition also known as balanitis xerotica obliterans). This needs to be aggressively treated by high-potency steroid creams for optimal outcomes and to prevent penile cancer.
- Recurrent balanoposthitis (infections of the foreskin and glans). These can be caused by bacteria or yeasts, and are treated by improving genital hygiene and topical or oral antibiotics.
- Penile cancer. This can lead to scarring, ulceration and changes in the pigmentation, and requires urgent medical care.
In phimosis that has persisted from childhood into adulthood, there may not be any of these underlying causes. In adults who develop phimosis for the first time, it is important to get checked by a doctor as treatment depends on the underlying cause.
Phimosis treatment: creams first, surgery rarely
Most adult phimosis is treated with a course of topical steroid cream and gentle stretching, and the majority of men avoid circumcision altogether.
A swab to check for infections may be performed by a doctor, and less commonly a skin biopsy if an autoimmune condition or cancer is suspected.
In those with no underlying cause for their phimosis (i.e. it has just persisted from childhood and there is no recurrent infection or autoimmune condition) treatment involves a trial of steroid cream to loosen the foreskin, good genital hygiene. In those whose foreskins still don’t retract past the glans, surgical treatment (a circumcision) may be offered.
Phimosis is a common condition, and the prognosis is generally excellent for people who don’t delay seeking help from their doctor.
What cream is used for phimosis?
Phimosis is usually treated with a topical steroid cream which works by softening and thinning the tight ring of foreskin so that it will stretch, and for many men it avoids the need for surgery altogether.
The creams used are moderate to potent steroids. A typical course is twice daily for 4-8 weeks, applied alongside gentle daily stretching. Most men notice a change within two to three weeks, but the full course matters: stopping early is one of the commonest reasons treatment appears not to work.
Around two in three cases resolve completely or partially with a steroid course, and a second course is often reasonable if the first one helps but doesn’t finish the job. Because prolonged use of potent steroids can thin the skin, the course is deliberately time-limited and should be supervised by a doctor rather than repeated indefinitely.
How to apply cream for phimosis
- Wash and dry your hands.
- Gently draw the foreskin back only as far as it moves comfortably, to the point of resistance, never past it.
- Apply a small amount of cream to the tight band itself and to the inner surface of the foreskin, then return the foreskin forward over the head of the penis.
Do this twice a day or as per your doctor’s instructions. Once the skin starts to loosen, add gentle stretching: hold the foreskin at the point of mild tension for 30 to 60 seconds, a few times in a row, once a day. It should never be painful.
Two things matter more than the technique. Never force the foreskin back. Forcing causes tearing, scarring and a tighter foreskin than you started with. And always slide it forward again afterwards; a foreskin left retracted behind the head of the penis can swell and become trapped, which is a medical emergency called paraphimosis.
Stop and see a doctor if you get pain, bleeding, splitting of the skin, or if there’s no change at all after eight weeks.
Can I buy phimosis cream at a chemist?
Not the ones that work. Mild steroid creams are available over the counter at any Australian pharmacy but may not be strong enough to loosen the tight band in phimosis.
The moderate and potent steroid creams used to treat phimosis are prescription-only in Australia, so no pharmacy can supply them without a script. You’ll typically need a doctor to examine or assess you first, partly to confirm it’s phimosis, and partly because a tight foreskin that develops in adulthood can be a sign of an underlying condition such as lichen sclerosus, which is treated differently and more urgently.
Don’t use a leftover steroid cream prescribed for somewhere else on your body. Genital skin is thinner and absorbs more, and the wrong strength used for too long may cause its own problems.
Which doctor should I see for phimosis?
Start with your GP. Most phimosis is diagnosed on history and examination and treated with a prescription cream, without needing a specialist. A urologist is involved only if the cream course fails, or if there are signs of an underlying cause such as lichen sclerosus. If it is difficult to raise in person, a telehealth consult is a reasonable place to start, an Australian GP can assess you, provide advice and send a script to your phone if appropriate.
