Involuntary unwanted erections are extremely rare after spinal cord injury (SCI). A sudden loss of sympathetic tone to the pelvic vasculature following SCI causes an increase in the parasympathetic tone and uncontrolled arterial blood flow into the penile sinusoidal spaces. When occurring immediately after an acute SCI, it is generally self-limiting and settles within a few hours. In contrast, recurrent, unwanted erections in patients with chronic SCI are more unpredictable in frequency and duration and may require treatment. We present a case of recurrent involuntary unwanted erections in a patient with chronic SCI after a stab wound to his neck and review the pathophysiology and available management options.

Effect of Propofol Versus Sevoflurane on Erections during Narcosis in Transurethral Surgery: The PENIS Trial.

Penile erection is unwanted during transurethral interventions as it may be associated with adverse events such as impaired access, prolonged operation time, abortion of the procedure, or a need for ancillary measures to reach penis flaccidity, such as intracorporeal injection of vasoactive drugs. In recent years, anesthesia with propofol has been favored over sevoflurane for environmental reasons. To the best of our knowledge, there have been no prospective randomized clinical trials evaluating the impact of general narcosis medications on the risk of such unwanted penile erections during transurethral surgery.

Priapism, an unwanted, painful, prolonged erection that is unrelated to sexual stimulation, is a common complication of sickle cell disease (SCD). Priapic events in SCD are stuttering, meaning they occur repeatedly with intervening periods of detumescence. Without health care intervention, repeated episodes can lead to erectile dysfunction.
