Medical check-ups will be performed by doctors who are experienced in the treatment of male sexual dysfunction. These will be conducted 1, 3 and 6 months after completing each of the Li-ESWT protocols. EHS and IIEF-5 scores will be determined at these consultations, as well as the presence or absence of adverse events related to the therapy. A second measurement of penile blood flow will be taken with doppler echography one month after completing each of the protocols.
