Reference	Objective	No. of patients	Sex	Stimulation technique	Recording site	Results	Evidence
Ertekin et al., 1987	To determine the diagnostic value of the pSSR in diabetic impotent men with or without peripheral polyneuropathy	32	M	Penile electrical and mechanical	Genital skin	Ab/↑ Lat/↓ Amp: 53%; No differences related to the polyneuropathy	Class 2
Ertekin et al., 1990	To determine the diagnostic value of the pSSR in alcoholic impotent men with or without peripheral polyneuropathy	15	M	Penile electrical and mechanical	Genital skin	N.D.	Class 2
Alves et al., 1997	To determine the diagnostic value of the pSSR in patients with amyloidotic neuropathy and EDs	15	M	Penile electrical stimulation	Palm skin; Plant skin	Ab/↑ Lat: 60% for SSR recorded at the palm and 93% at the sole of the foot	Class 2

Abbreviations: pSSR=perineal sympathetic skin response; EDs=erectile dysfunctions; M=male; Ab=absent response; Lat=latency; Amp=amplitude; N.D.=not significantly different from normal values; SSR=sympathetic skin response.
