In this concise monologue, Dr. Anne Truong explains that sexual arousal—and consequently erections—originate in the brain, not the penis. She emphasizes that if a man is not becoming aroused, he should first assess his testosterone levels and eliminate detrimental habits. She also highlights that psychological states such as depression, anxiety, and stress can suppress arousal. Dr. Truong notes that six physiological systems contribute to erection, underscoring the brain as the largest sexual organ that initiates the process.
