== Sensory Input and Local Vascular Response ==
'''''Nervous Component'''''
* Arousal driven
* Must be appropriate sensory stimuli (tactile, visual, olfactory, auditory) in order for the central nervous system to be stimulated for efferent events to cause erection.
** Extrinsic stimuli are called '''erotogenic stimuli'''.
'''''Local Vascular Component'''''
* Pressure compresses the venules through which blood exits the penis.
