Gum Chewing Therapy vs. Biofeedback for Lifelong Premature Ejaculation: A Prospective Randomized Comparative Study.

Abstract

This study aimed to compare the effectiveness of gum-chewing therapy (GCT) and biofeedback therapy (BFT) in patients with lifelong premature ejaculation (LPE). Between April and October 2025, 84 patients presenting to the urology outpatient clinic were evaluated. Inclusion criteria were a Premature Ejaculation Diagnostic Tool (PEDT) score >11 and an intravaginal ejaculatory latency time (IELT) <60 seconds. After exclusions, 75 patients were randomly assigned to the GCT (n = 39) or BFT group (n = 36). Patients in the GCT group performed rhythmic gum chewing starting 20 minutes before intercourse and continuing until ejaculation, while patients in the BFT group were evaluated after completing therapy sessions. IELT and PEDT scores were assessed at 1 and 3 months. Data from 61 patients (GCT:33, BFT:28) who completed the study were analyzed. The groups were comparable in age and baseline IELT and PEDT scores. Both groups demonstrated significant improvements in IELT and PEDT outcomes at follow-up (p < 0.001). Although numerical improvements were greater in the GCT group, intergroup differences were not statistically significant. Gum-chewing therapy may represent a simple, discreet, low-cost, non-pharmacological treatment option for LPE.
