Randomized, experimental, non-inferiority clinical trial to determine the comparative effectiveness and safety of two protocols used in the treatment of Erectile Dysfunction (ED) with Low-Density Shock Waves (Li-ESWT), for patients seen at the Boston Medical Group's Bogota center. Protocol 1: Consists of five sessions, one per week, with 3000 pulses at 0,15 mg/mm2, at a frequency of 4 Hz. The distribution of the shocks will be 2000 pulses to the body of the penis and 1000 pulses at its base. Total duration: 5 weeks. Protocol 2: Consists of six sessions, two per week, with 1500 pulses each one at 0.1 mJ/mm2, at a frequency of 4 Hz. The distribution of the shocks will be 900 pulses to the body of the penis and 600 pulses at its base. Total duration: 3 weeks.
