The study reveals that while approximately one in two Japanese men may have ED, a significant portion remains in an 'unaware' category, not recognizing their condition.
Only about 20% of men have experience discussing ED with others, highlighting the high psychological hurdles to seeking advice. Notably, 35.4% of men in their 20s reported having been teased about ED, suggesting that the environment in Japan is not conducive to open discussion for those aware of their condition.
Furthermore, Japanese men tend to rely on lifestyle improvements such as 'exercising' or 'drinking energy drinks' rather than medical approaches like consulting healthcare providers or taking prescribed medication, a trend lower than in other countries.
Key Survey Findings:
- 66.9% of Japanese men are aware of ED, but only 60.9% correctly understand its medical definition.
- Approx. 1 in 2 men may have ED (including EHS grade 3 or lower).
- Only about 20% have experience discussing ED.
- 35.4% of men in their 20s reported having been teased about ED.
- Most rely on energy drinks or exercise; medical approaches are less common.
ED is defined as a persistent or recurrent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. While the awareness rate in Japan is 66.9%, the accuracy of that understanding is limited.
Based on the Erection Hardness Score (EHS), only 45.3% of respondents were 'Grade 4 (completely hard),' suggesting that nearly half might be experiencing ED. Many men with lower EHS scores do not consider themselves to have ED, indicating a gap between self-perception and reality.
Psychological barriers, such as the fear of being teased, discourage men from seeking help, with only 20% taking action. Additionally, a lack of dialogue between partners contributes to delays in treatment.
