Answer to Question 1

1, 2, 3, 5
Rationale: Sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra) have been approved by the FDA for the treatment of erectile disorder. These newer impotence agents block the action of phosphodiesterase-5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a compound that is required to produce an erection. Phentolamine has been used in combination with papaverine in an injectable form that increases blood flow to the penis, resulting in an erection. Apomorphine acts directly on the dopamine receptors in the brain. This mode of stimulating dopamine in the brain is thought to enhance the sexual response. Zoladex is a treatment for prostate cancer, not erectile dysfunction.

Answer to Question 2

2, 3, 5
Rationale: Categories of paraphilic disorders include voyeuristic disorder (observing unsuspecting people, who are naked, dressing, or engaged in sexual activity), frotteuristic disorder (touching or rubbing against a non-consenting person), and fetishistic disorder (using nonliving objects in sexual ways). Exhibitionistic disorder is a paraphilic disorder but involves the urge to show one's genitals to unsuspecting strangers. Other categories include sexual masochism disorder, sexual sadism disorder, and transvestic disorder.
