It’s official: Sex is good for the mammalian brain

From a Princeton researcher publishing in PLoS ONE, we hear important news on brain health: “Sexual Experience Promotes Adult Neurogenesis in the Hippocampus Despite an Initial Elevation in Stress Hormones”:

Chronic sexual experience no longer produced an increase in corticosterone levels but continued to promote adult neurogenesis and stimulate the growth of dendritic spines and dendritic architecture. Chronic sexual experience also reduced anxiety-like behavior. These findings suggest that a rewarding experience not only buffers against the deleterious actions of early elevated glucocorticoids but actually promotes neuronal growth and reduces anxiety.

This is in rats, but they’re mammals like us, so this will likely hold true for humans.

This key finding supports my suggestion that we should start a life extension dating service!  —Christine Peterson, Conference Chairman
