[Survey of Men in their 20s-50s] Approximately 15% of Men Correctly Understand They Have Phimosis. What are the Realities of Phimosis Perception and Concerns?

Realities of Phimosis Perception and Concerns

Although the term "phimosis" is widely known, how many men correctly understand its types and their own condition? Due to its delicate nature, it is not uncommon for men to keep their concerns to themselves without consulting anyone.

What are men's true feelings regarding discomforts experienced in daily life, reasons for hesitating to consult medical institutions, and awareness of health risks if left untreated?

Therefore, in collaboration with MS Clinic, we conducted a survey targeting 300 men nationwide in their 20s to 50s on "Realities of Phimosis Perception and Concerns."

41.7% responded, "I know there are several types of phimosis."

First, we asked about the extent of knowledge regarding "phimosis."

The result showed that 41.7% of respondents answered, "I know there are several types of phimosis," which was the most common response.

This was followed by "I know the term 'phimosis' but don't know the details" at 25.7%, "I don't know at all" at 19.3%, and "I accurately know the differences between physiological phimosis, paraphimosis, and true phimosis" at 13.3%.

Only about one-tenth of all men accurately grasp the differences in types, indicating that for many men, phimosis is a topic they "vaguely know about but don't understand in detail."

15.7% responded, "I correctly understand that I have phimosis."

Next, we asked about their self-perception of whether they have phimosis.

The results were: "I correctly understand that I do not have phimosis" at 26.0%, "I don't know/cannot judge" at 25.7%, "I think I do not have phimosis" at 19.3%, "I correctly understand that I have phimosis" at 15.7%, and "I might have phimosis" at 13.3%.

Combining "I correctly understand that I have phimosis" and "I might have phimosis," approximately 29% of men recognize that they have phimosis or potentially have it.

On the other hand, 25.7% responded, "I don't know/cannot judge," indicating that about one in four men cannot accurately assess their own condition.

74.7% responded that they have "physiological phimosis."

Next, we asked those who responded that they have or might have phimosis about the type of phimosis they have.

The result showed that "physiological phimosis (glans is exposed during erection)" accounted for the majority at 74.7%.

This was followed by "I don't know my type" at 16.1%, "paraphimosis (difficult to return to original state after retraction, causes pain)" at 6.9%, and "true phimosis (glans is not exposed even during erection, difficult to retract)" at 2.3%.

Physiological phimosis is considered a relatively common type among Japanese men, but about one in six responded, "I don't know my type," suggesting that even within phimosis, the degree of symptoms varies, and self-diagnosis is often difficult.

"Have not felt any particular concerns or discomforts" was the most common at 43.7%.
