Group I (Control), will be operated with the same procedure but without electric current, and using "placebo needles" of the same size (Streitberger Placebo-Needle ® , Asiamed, Pullach, Germany), which will not pierce the surface of the patient's skin, but will cause a prick sensation. This process will be developed by resting the needle on the skin of the patient's perineum and pushing the handle of the needle until it touches the surface of the skin, producing in the patient the impression of penetration, although this is not the case.

Group II will undergo continuous stimulation at a frequency of 20 Hertz, a pulse width of 200 μs and for a total of 20 minutes. The intensity will be set at the maximum tolerated by the patient.

Group III, will be intervened with continuous stimulation at a frequency of 50 Hz,a pulse width of 200 μs (18) and for a total of 20 minutes. The intensity will be set at the maximum tolerable threshold. In case the patient does not tolerate the treatment, due to increased fatigue, the 50 hertz will be alternated with the 20 hertz in bursts.

It is an index that assesses erectile function in a purely subjective way. It is the most widely recognized and used, and consists of six questions in which the frequency and firmness of erection, penetration capacity, capacity and frequency of maintenance and confidence in erection are evaluated. According to the questionnaire, dysfunction is classified as: no ED (26-30 points), mild (22-25 points), mild to moderate (17-21 points), moderate (11-16 points) and very strong (6-10 points). A score equal to or greater than 4 points will be considered a significant change. Measurement pre-, one week after the intervention, one month after the intervention and 3 months after the intervention.

significant changes will be considered to be those men who improved by more than 3 points what in the initial phase was below a score of 2 points. The questionnaire score depends on the rating of erection hardness according to the following parameters: 0 (penis does not enlarge); 1 (penis is larger, but not hard); 2 (penis is hard but not hard enough for penetration); 3 (penis is hard enough to penetrate, but not completely hard); and 4 (penis is completely hard and rigid). Measurement pre-, one week after the intervention, one month after the intervention and 3 months after the intervention.

Time to ejaculation is considered and should be between 3 and 6 minutes. A duration of less than one minute is considered premature ejaculation, and a duration between one minute and one and a half minutes is considered probable premature ejaculation. Measurement pre-, one week after the intervention, one month after the intervention and 3 months after the intervention.

Helps identify patients who may be suffering from premature ejaculation. Measurement pre-, one week after the intervention, one month after the intervention and 3 months after the intervention.
