A Single-Center Prospective Interventional Study Comparing Pelvic Floor Muscle Training Alone Versus Combined With Extracorporeal Magnetic Innervation in Men With Premature Ejaculation

This is a single-center, prospective interventional study that prospectively evaluated two nonpharmacological approaches for the management of premature ejaculation (PE): pelvic floor muscle training (PFMT) alone versus PFMT combined with extracorporeal magnetic innervation (ExMI). Adult men with clinically diagnosed PE were enrolled at a university hospital physiotherapy/urology clinic and followed over an 8-week intervention period. The trial was open-label with parallel groups; participants received the treatment used in clinical practice (PFMT only or PFMT+ExMI), and outcomes were collected prospectively according to a predefined protocol.

PE is common and impairs quality of life. PFMT may improve neuromuscular control of the pelvic floor, and ExMI delivers chair-based magnetic stimulation to activate pelvic floor musculature. We hypothesized that adding ExMI to standard PFMT would produce greater improvements in pelvic floor function and patient-reported sexual outcomes than PFMT alone.

All participants received structured education and a progressive, home-based PFMT program supervised during the 8-week period. The PFMT+ExMI group additionally underwent chair-based magnetic stimulation delivered per the clinic's predefined protocol targeting pelvic floor muscles.

Assessments were performed at baseline and post-intervention (week 8), with short-term follow-up where feasible. Primary outcomes were pelvic floor muscle displacement distance and endurance measured with real-time suprapubic ultrasonography under standardized instructions. Secondary outcomes included the Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function (IIEF-5), Male Sexual Function Inventory-Short Form (MSFI-SF), WHOQOL-BREF sexual satisfaction item, Global Perceived Effect, and safety/adverse events.
