Final answer:
Hypoactive sexual desire disorder or sexual interest/arousal disorder can be influenced by hormonal imbalances, medical conditions like hypogonadism, and psychological factors. Erectile dysfunction in men is an example of such disorders, with associations to physical and emotional conditions that affect sexual function.
Step-by-step explanation:
The individual with the greatest likelihood of hypoactive sexual desire disorder or sexual interest/arousal disorder may be influenced by various factors including hormonal imbalances, certain medical conditions, and psychological factors. For example, disorders that involve abnormal hypothalamic function are often associated with hypogonadism and reduced sexual function such as in Prader-Willi syndrome. Because the hypothalamus plays a role in endocrine function, hormones like testosterone are significant in influencing sexual motivation and behavior. Moreover, in both males and females, sexual motivation varies with circulating testosterone levels. Disorders like erectile dysfunction (ED) in men can also contribute to sexual dysfunction and are associated with several physical and emotional conditions that can hamper sexual performance and desire. These can include diabetes, vascular disease, psychiatric disorders, and prostate disorders, among others.
Both males and females show arousal, but the intensity and duration of the sexual response can vary greatly between the genders.
