Step-by-step explanation:
Erectile Dysfunction as a Sexual Arousal Disorder in Men
In men, the disorder classified as a sexual arousal disorder is A) Erectile Dysfunction (ED). This condition is characterized by the regular and repeated inability of a sexually mature male to obtain or maintain an erection. The prevalence of ED increases with age, affecting approximately 40 percent of men at age 40 and nearly 70 percent by the age of 70. Erectile Dysfunction is associated with a variety of physiological and psychological causes, including diabetes, vascular disease, psychiatric disorders, prostate disorders, and the use of some drugs, such as certain antidepressants. Additionally, ED can be caused by physical conditions that lead to interruptions in the vasodilation pathway, which is crucial for achieving an erection.
Understanding the underlying causes of this disorder is essential, as they may vary from medical conditions like diabetes or kidney failure to lifestyle factors such as tobacco smoking and poor dietary habits. Psychological causes, though less common, can also play a role and include stress, performance anxiety, or other mental disorders. Identifying the correct cause is necessary for choosing the appropriate treatment, which may range from medication to therapy, lifestyle changes, and treating any underlying health issues.
