As a medical professional with expertise in urology, I can provide you with an informed perspective on the prevalence of phimosis.

Phimosis is a condition where the foreskin of the penis is too tight to be pulled back over the glans. It is a relatively common condition in young boys, affecting approximately 90% of full-term male infants at birth. However, it's important to note that in most cases, this is a physiological phimosis, which means it is a normal part of the developmental process and often resolves on its own as the child grows.

In older boys and adults, the prevalence is significantly lower. It is estimated that around 10% of boys have non-retractable foreskin by the age of 17. In adults, the occurrence is less common, with some studies suggesting a prevalence of less than 1%.

It's crucial to differentiate between physiological phimosis, which is common and typically resolves with age, and pathological phimosis, which may require medical intervention due to complications or lack of spontaneous resolution.

In the United States, about 10% of boys are born with phimosis. A larger percentage of boys are born with a milder form of phimosis, in which the foreskin can only partially retract. Normally, by the time a boy reaches 16 years of age, he should be able to easily retract his foreskin. This is true in 1% to 5% of men.read more >>
