What can go wrong
Under-recognition leads to inappropriate psychiatric labeling. Evidence is limited to small case series; there is no controlled treatment data. Any neuromodulatory or pharmacologic intervention requires neurological evaluation.
This is something to take to a clinician. The Atlas can tell you what is known about restless genital syndrome in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
Restless genital syndrome combines the diagnostic criteria of PGAD with restless legs syndrome and/or overactive bladder. Waldinger and colleagues reported the first male cases and provided evidence that ReGS reflects small fiber sensory neuropathy (SFSN) of the pudendal nerve and its genital end branches. Sensory testing typically reveals static mechanical hyperesthesia in the dorsal nerve distribution.
The genital analogue of restless legs - and a small-fiber neuropathy signature.
What people take it for
These are the reasons people give for taking it. They are not effects it has been shown to have.
How it is supposed to work
Typical sensory abnormalities of the genital end branches of the pudendal nerve, demonstrable in both sexes, point to small fiber sensory neuropathy as a common cause. The overlap with restless legs syndrome suggests a shared dopaminergic and small-fiber substrate rather than a purely psychogenic origin.
What people get wrong
Often saidRestless genital syndrome is purely psychological
ActuallyCase-series evidence links it to small fiber sensory neuropathy of the pudendal nerve, arguing for an organic peripheral-nerve basis in many patients.
Who profits, and who pushes back
Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.
