Question

Quizplus · Accepted Answer

The release of hormones from the pituitary and hypothalamus, including dopamine and testosterone, is likely responsible for Pei-Pei's surge of excitement and sexual desire. These hormones are associated with feelings of reward and arousal, and are activated in response to pleasurable social and sexual stimuli like meeting someone new and attractive. Choice A is unlikely because there is no mention of drug use. Choice B is incorrect because oxytocin is actually associated with increased bonding and attachment, and a decrease would likely reduce feelings of sexual desire rather than increase them. Choice D is incorrect because physiological and psychological interdependence refers to a state of emotional connection and mutual influence between individuals, but does not necessarily correlate with sexual desire.
