There will be 3 weekly therapy sessions for 12 continuous weeks, lasting 30 minutes each. 20 Hertz with a pulse width of 200 µsec will be administered in each session. The intensity will be applied to each patient depending on individual tolerance. TENT therapy will be performed as follows:

1. The active electrode is placed and adhered 3 - 5 cm above the internal malleolus and 1 cm behind the tibia.

The second reference electrode is attached to the calcaneus.

Continuous current, Frequency: 20 Hz Pulse width: 200 µsec, Time: 30 min. Intensity: to the patient's tolerance, gross motor perception to verify correct application, upon reaching it, increase the intensity to clearly sensory activation.

They will also receive dapoxetine placebo (capsules with only excipients without active ingredient) as needed, taken 3 to 4 hours before sexual intercourse during the 12 weeks of the intervention.

Patients in this group will receive dapoxetine 30 mg, taken 3 to 4 hours before sexual intercourse, for the 12 weeks of the study. In addition to the medication, patients will receive three weekly sessions of placebo therapy for twelve continuous weeks, lasting 30 minutes each. For this, the black electrode will be placed on the external malleolus and the red one 4 finger widths towards the head on the lateral edge of the tibia. 20 Hertz with a pulse width of 200 µsec will be administered in each session.

Tens therapy + standard treatment (dapoxetine 30 mg as needed).

Patients in this group will receive electrostimulation therapy of the posterior tibial nerve, 3 weekly therapy sessions for 12 continuous weeks, lasting 30 minutes each. 20 Hertz with a pulse width of 200 µsec will be administered in each session. The intensity will be applied to each patient depending on individual tolerance.

In addition to the therapy, patients in this group will receive dapoxetine as needed, taken 3 to 4 hours before sexual intercourse during the 12 weeks of the intervention.

There will be 3 weekly therapy sessions for 12 continuous weeks, lasting 30 minutes each. 20 Hertz with a pulse width of 200 µsec will be administered in each session. The intensity will be applied to each patient depending on individual tolerance. TENT therapy will be performed as follows:

1. The active electrode (cathode - red) is placed and adhered 3 - 5 cm above the internal malleolus and 1 cm behind the tibia.

The second reference electrode (anode - black) is attached to the calcaneus.

The equipment must previously be programmed under the following parameters:

Continuous current Frequency: 20 Hz. Pulse width: 200 µsec Time: 30 min. Intensity: to the patient's tolerance, gross motor perception to verify correct application, upon reaching it, increase the intensity to clearly sensory activation.

Average change in intravaginal latency time, measured with a stopwatch by the couple.

Average change in intravaginal latency time, measured with a stopwatch by the couple.

Proportion of patients with clinical improvement in premature ejaculation, defined as a three-fold increase in the intravaginal ejaculatory latency time.
