The relationship between the location of the lesion and sexual dysfunctions.

Brain Lesions	Sexual Dysfunction
Medial frontal cortex	Erectile dysfunction, hyposexuality
Temporal cortex	Hypersexuality
Parietal lobe Right Left inferior lobule	Altered cognitive arousal (neglect) Altered cognitive arousal (reduced sensory awareness)
Anterior cingulate cortex	Erectile dysfunction
Insula and claustrum	Altered motivational arousal Erectile dysfunction
Amygdala	Anhedonia, altered autonomic arousal Bilateral damage could lead to hypersexuality (e.g., Kluver–Bucy syndrome)
Hypothalamus	Erectile dysfunction Ejaculatory disorders (sometimes)
Thalamus	Erectile dysfunction
Nucleus accumbens	Altered motivational arousal
Left basal ganglia	Decreased libido
Mesodiencephalic tegmentum	Anhedonia
Cerebellum	Altered autonomic arousal Ejaculatory disorders Anhedonia Altered emotional arousal Ejaculatory disorders (left lesion)
