Dr. Anne Truong breaks down the four types of erections: morning wood, touch-triggered reflex erections, mentally-induced ones, and mixed arousal erections. Each uses different physiological pathways involving nitric oxide and the parasympathetic nervous system. Mediterranean diet, exercise, sleep, and stress reduction all improve function.
