Step-by-step explanation:
To meet the criteria for an interest/arousal disorder, a male must experience symptoms 75% of the time for at least 6 months. Erectile dysfunction (ED) is a condition related to this where a person has difficulty either initiating or maintaining an erection. Several factors such as aging, diabetes, vascular disease, psychiatric disorders, prostate disorders, use of certain drugs like antidepressants, and low testosterone levels due to testicular problems can affect erectile function. These issues may interfere with the vasodilation pathway essential for achieving an erection.
