PPP Risk Factors – Why Some Men Get Pearly Penile Papules?
If you have Pearly Penile Papules, you may wonder why you developed them when other men did not. PPP are a normal anatomical variation, but the exact reasons they develop are not fully understood.
This guide explains what research tells us about their development, associated factors and natural history.
Primary Information Category: Risk Factors & Development. This guide explains the factors associated with PPP, including age, puberty and circumcision, while separating established evidence from theories about hormones, genetics, skin and keratinisation.
Quick Answer:
There is no single proven risk factor that explains why one man develops PPP and another does not. PPP commonly become noticeable during late adolescence or early adulthood and tend to become less apparent with age. Circumcision has been associated with PPP prevalence in some studies, but findings are inconsistent. There is no established evidence that sex, masturbation or poor hygiene causes PPP.
Quick Clinical Information & Reassurance from Dr Josh:
“Men often want a reason for something they have noticed on their penis. With PPP, we can be much more confident about what they are than about exactly why one individual man develops them. That distinction matters. PPP are a recognised normal anatomical variation, and not having a precise individual cause does not mean that you have missed something or done something wrong.”
Why Do Some Men Get Pearly Penile Papules?
The honest medical answer is that we do not yet know exactly why some men develop visible PPP and others do not.
PPP are considered a normal anatomical variation of the penis. They are typically found around the corona or sulcus of the glans and are often arranged in one or more rows.
They are commonly noticed during late adolescence or early adulthood. Research has identified some patterns associated with PPP, particularly age and circumcision status, but these associations do not provide a simple explanation for every individual man.
This distinction is important.
An association means that two things are found together more often than might otherwise be expected. It does not automatically mean that one causes the other.
For a man who has just discovered PPP, that means there is no scientific reason to assume:
“I must have done something that caused this.”
Does Age Affect PPP?
Yes. Age is one of the clearest patterns seen in PPP research.
PPP are commonly reported in adolescents and young adults, and published studies generally find that they become less prevalent or less apparent as men get older.
A UK study found PPP in 38.3% of men under 25 compared with 11.4% of men over 50. More extensive PPP were also less common in the older group.
StatPearls similarly describes PPP as mainly occurring in late adolescence and early adulthood, with prevalence declining in older patients as the lesions become less apparent.

This does not mean that every man’s PPP will disappear with age.
Some men will continue to have visible PPP throughout adulthood.
The evidence tells us about a population pattern, not a guaranteed outcome for one individual.
Why Do PPP Become Noticeable During Puberty?
PPP are rarely observed in children and are commonly reported during or after puberty.
This timing is one reason researchers have considered whether normal developmental changes could be involved.
However, becoming noticeable around puberty does not prove that puberty hormones cause PPP.
Puberty involves many simultaneous changes to the body, including changes in genital development and skin appearance. PPP becoming apparent during this period tells us that they are associated with normal development, but it does not identify a particular biological trigger.
The most accurate conclusion is: PPP commonly become apparent around puberty, but their precise biological cause remains uncertain.
Are Hormones a Risk Factor for PPP?
There is no established evidence that a particular hormone or hormonal imbalance causes PPP.
Because PPP often become noticeable around puberty, it is reasonable to ask whether testosterone or another hormonal change is responsible.
At present, however, there is not enough evidence to identify a particular hormone level or hormonal imbalance as a recognised PPP risk factor.
It would therefore be misleading to tell a man that high testosterone causes PPP or that having PPP means he has a hormonal problem.
The timing around puberty is an observation.
It is not proof of a specific hormonal mechanism.
Does Circumcision Affect PPP?
Circumcision status has been associated with PPP prevalence, but the research is not completely consistent.
A UK study found PPP in 26.5% of circumcised younger men compared with 42.4% of uncircumcised younger men. The same study also found that PPP prevalence was unrelated to frequency of sexual intercourse or time since first intercourse.
Other research has produced different findings. StatPearls notes that although many studies report lower prevalence among circumcised men, at least one study found a higher prevalence in circumcised men.
This means circumcision status is an interesting epidemiological association, but it is not a simple explanation for why an individual man has PPP.
It also does not mean that circumcision should be undertaken to prevent or treat PPP.
Association is not the same as causation.
Does Having a Foreskin Increase the Risk of PPP?
Some studies have found PPP to be more common among uncircumcised men.
However, being uncircumcised does not mean that a man will develop PPP, and being circumcised does not guarantee that he will not.
The research therefore cannot be reduced to:
“A foreskin causes PPP.”
That would overstate what the evidence shows.
The more accurate statement is that some studies have found an association between circumcision status and PPP prevalence, while the overall evidence is mixed.
Does Skin Thickness Affect the Risk of PPP?
There is currently no established evidence that penile skin thickness is a recognised risk factor for typical PPP.
Men naturally differ in skin structure, pigmentation and appearance. These differences can affect how visible small papules are.
But visibility is not the same thing as development.
A man’s PPP may appear more obvious because of their size, colour, distribution, lighting or the way the skin is stretched.
There is currently no reliable clinical rule linking penile skin thickness with whether PPP will develop.
Does Keratinisation Cause PPP?
Keratinisation is a normal biological process involved in the development and maintenance of the skin.
Changes in skin structure or keratinisation may be discussed when considering how papules form, but there is no established evidence that an abnormal keratinisation pattern is a recognised risk factor for typical PPP.
This is an important distinction between a biological theory and a clinically established risk factor.
PPP are currently better understood as a normal anatomical variation than as the result of a known skin abnormality that men can identify or prevent.
Are Pearly Penile Papules Genetic?
A simple genetic cause of PPP has not been established.
It is possible that individual biological differences influence whether a man develops visible PPP, just as people naturally differ in many aspects of anatomy.
However, there is no established genetic test that predicts PPP and no recognised inheritance pattern that allows doctors to calculate an individual’s risk.
Having a father or brother with PPP does not mean that you will definitely develop them.
Equally, having no family history does not protect you from them.
The most accurate position is that a genetic contribution remains uncertain.
Does Sexual Activity Increase the Risk of PPP?
There is no established evidence that sexual activity causes PPP or increases an individual’s risk of developing them.
This is particularly important because PPP are often noticed during the same broad stage of life when many men become sexually active.
The two events can therefore appear connected even when there is no causal relationship.
A UK study found that PPP prevalence was unrelated to either frequency of sexual intercourse or time since first sexual intercourse.
DermNet also states that PPP are not due to sexual activity.
PPP are not acquired from a sexual partner.
Why Can PPP Look More Noticeable After Sex?
PPP can sometimes appear more prominent after sexual activity without the sexual activity having caused them.
An erection stretches the skin around the glans, which can make small papules easier to see. Changes in blood flow, moisture, skin tension and lighting may also alter their appearance.
This can create the impression that:
- more papules have appeared;
- existing papules have grown;
- sex has caused them; or
- PPP are becoming worse.
A change in visibility is not necessarily a change in the underlying condition.
If the papules remain typical in appearance and distribution, becoming easier to see under certain circumstances does not mean that sexual activity has created them.
Does Masturbation Increase the Risk of PPP?
There is no established evidence that masturbation causes PPP.
As with sex, masturbation may make existing papules easier to see because of erection and stretching of the skin.
That should not be confused with creating new PPP.
There is therefore no recognised medical recommendation for men with PPP to stop masturbating in an attempt to prevent them.
Does Poor Hygiene Increase the Risk of PPP?
No.
PPP are not caused by poor hygiene.
DermNet specifically states that PPP are not due to lack of hygiene.
A man may notice papules and immediately start washing more frequently because he assumes that something has accumulated on the skin.
But PPP are not dirt and are not a sign that the penis has not been cleaned properly.
Normal genital hygiene is appropriate.
Excessive washing or scrubbing is not a recognised way of preventing PPP and may instead irritate sensitive genital skin.
Why Do Some Men Have PPP and Others Don’t?
This is ultimately where the limits of current medical knowledge become important.
We can describe several patterns:
- PPP are common.
- They are often noticed during or after puberty.
- They are particularly common in younger adult men.
- Their prevalence tends to decline with age.
- Some studies find differences according to circumcision status.
But these observations do not produce a simple formula for predicting which individual man will develop PPP.
Two men can have similar ages, lifestyles, hygiene, sexual histories and circumcision status, yet only one may have visible PPP.
That is not unusual in medicine.
Normal anatomical variation does not always have a single identifiable cause.
Are There Other Proven PPP Risk Factors?
At present, there is no established list of lifestyle or behavioural risk factors that allows doctors to predict who will develop PPP.
There is no proven association with:
- frequency of masturbation;
- frequency of sex;
- number of sexual partners;
- poor hygiene;
- a particular diet;
- exercise;
- supplements;
- shaving.
Some biological explanations have been considered, but the evidence is not sufficient to turn theories about hormones, genetics, skin structure or keratinisation into established individual risk factors.
This distinction matters because an unsupported “risk factor” can easily become a source of unnecessary self-blame.
Can You Tell Beforehand Whether You Will Develop PPP?
No.
There is currently no clinical test that can tell a healthy man whether he will develop PPP in the future.
There is also no recognised screening programme for PPP.
For most men, PPP are discovered because they become visible rather than because something has gone wrong.
If unfamiliar penile bumps appear, the useful question is therefore not:
“What did I do to cause these?”
It is:
“Do these actually look like PPP, and do I need a medical assessment?”
That change in perspective can prevent a great deal of unnecessary anxiety.
Assurances on the PPP Risk Factors
If you have PPP, it is understandable to want to know why you have them.
But the absence of a precise individual explanation does not mean that something has gone wrong.
Research gives us useful clues. PPP commonly become noticeable around puberty and early adulthood, and they tend to become less apparent with age. Circumcision status has also been associated with PPP prevalence in some studies, although the evidence is mixed.
What medicine doesn’t currently have is a simple explanation such as:
“You developed PPP because you did X.”
PPP are not known to result from poor hygiene or sexual activity.
You do not need to search your past behaviour for a cause.
The most useful step is to establish whether the bumps are typical PPP and then understand what that diagnosis means.
Knowledge gained from 18 years of clinically helping Men with Penile Papules
Dr Josh’s Direct Answer on PPP Risk Factors: “One of the difficult things for men with PPP is accepting that we can be very confident about what the papules are while being less certain about exactly why that particular man developed them.
Patients understandably want a cause. They may ask about hormones, hygiene, sex, masturbation, circumcision or genetics.
I think it is important to distinguish what we know from what we are merely able to theorise.
PPP commonly become noticeable around puberty and early adulthood, and many become less apparent with age. There are also interesting associations with circumcision status. But these observations do not allow us to explain every individual patient.
That is not a reason for concern. It is simply where the evidence currently stands.
My priority is to make sure the man understands what he has, knows what it means medically, and does not turn uncertainty about its origin into unnecessary anxiety.”
Frequently Asked Questions
PPP are common and usually become noticeable around puberty or early adulthood. Age and circumcision status show associations in research, but no single cause explains why an individual man develops them. You did not do anything to cause them.
