The primary premature ejaculation (PPE) is a common male sexual disorder. We proposed a novel behavioral therapy for PPE through regular penis-root masturbation (PRM). Nine heterosexual men with PPE completed the self-controlled study. After a 3-month PRM training, the median intravaginal ejaculatory latency time (IELT) increased from 60 s to 180 s (P = 0.018), and the mean Premature Ejaculation Diagnostic Tool (PEDT) score decreased from 14.8 ± 3.7 to 12.8 ± 4.1 (P = 0.074). Five out of eight patients had the prolonged dorsal nerve somatosensory evoked potential (DNSEP). The results suggest that PRM has a short-term therapeutic effect. Randomized controlled trials are needed to validate the efficacy.
