Final answer:
Male erectile dysfunction is one of the best-researched sexual dysfunctions and is increasingly viewed as having strong physical contributors.
Step-by-step explanation:
True
Erectile dysfunction (ED) is a condition in which a person has difficulty either initiating or maintaining an erection. It is one of the best-researched sexual dysfunctions and is increasingly viewed as having strong physical contributors. The prevalence of ED increases with age and is associated with conditions such as diabetes, vascular disease, psychiatric disorders, prostate disorders, and the use of certain drugs. These physical and emotional factors can lead to interruptions in the vasodilation pathway, resulting in an inability to achieve an erection.
