A perineal probe (1) comprising a substantially cylindrical support rod (2) in an insulating material is provided, defining an axial direction (1 a) and a circumferential direction (1b), an end portion (3), constituting the inner end of said support rod (2), a grip (4) for said perineal probe (1) positioned on the support rod (2) at the opposite end of said end portion (3), 2n electrodes (5) positioned on the outer surface (2a) of the support rod (2), with n being a whole number greater than one, in which each electrode (5) extends for a circumferential portion ranging from 60° to 180°, in which the electrodes (5) are two by two aligned in an axial direction (1a) and reciprocally distanced in a circumferential direction (1b), are in addition n by n aligned in a circumferential direction (1b) and distanced in an axial direction (1a), and in which each electrode (5) is connected to a different electric output (5a).
