No geographic variation in prevalence has been noted for pearly penile papules.
No racial predilection has been confirmed for pearly penile papules. Reports suggesting an increased incidence in African American males may reflect an increase in uncircumcised men in that population.
Pearly penile papules are noted most commonly in males in their second or third decades of life, with a gradual decrease in frequency with aging.
The incidence of pearly penile papules reportedly ranges from 8-48%. Several reports suggest an increased incidence of pearly penile papules in uncircumcised versus circumcised men (22% vs 12%,respectively). One study found an increase in frequency in black versus white men, in those circumcised (21% vs 7%, respectively) and uncircumcised (44% vs 33%, respectively).
Because of their anatomic distribution, pearly penile papules are noted only in men.
