Final answer:
The percentage of men under 59 years of age with erectile dysfunction (ED) is reported to be about 40 percent for those around age 40, with the prevalence increasing with age. Other factors contributing to ED include health conditions, medication use, and smoking. The exact percentage for those under 59 is not provided but can be extrapolated from available age group data.
Step-by-step explanation:
The percentage of men under 59 years of age who experience erectile dysfunction (ED) varies by age group. According to the provided data, the combined prevalence of minimal, moderate, and complete ED is about 40 percent for men at the age of 40. This condition can be associated with various health issues, including diabetes, vascular disease, and psychiatric disorders. It is also known that smoking can significantly increase the risk of ED. Moreover, conditions of the male reproductive system such as prostate disorders, use of certain medications, and low testosterone levels can contribute to the development of ED.
While the table provided does not specify the percentage for men under 59 directly, it does give percentages for age groups that fall within this range, with the percentage for men aged 51-60 being approximately 21.9 percent. However, this does not directly answer the question for men under 59 but gives an indication that ED is not uncommon in this age group.
