Penile Nerve Inhibitory Impulse Syndrome (PNIIS) is a type of male erectile dysfunction caused by physiological and/or psychological issues. The primary symptom of Penile Nerve Inhibitory Impulse Syndrome (PNIIS) is a weak or absence of erection. The main causes are injuries to the Central Nervous System (CNS), such as brain and spinal cord injuries, as well as psychological issues. Psychological issues include overuse/addiction to porn, traumatic or stress inducing sexual history, and sexual anxiety. The effect of the physiological/psychological injury is the inhibition of the excitatory nerve impulse transmitted from the CNS to the Penile Nerve (Pudendal Nerve via the Dorsal Nerve of the Penis) creating an impartial erection or the absence of erection, even during events of high sexual stimulation and attraction.
