The primary endpoint of our study was to evaluate the effectiveness of PFM rehabilitation by measuring the change, from baseline, in IELT and the self-administered Premature Ejaculation Diagnostic Tool (PEDT) over a follow-up period of 36 months. The secondary endpoint was to investigate the long-term effectiveness of PFM rehabilitation in training patients to recognize when and how to control the muscles involved in the ejaculatory reflex.
