Complementary, surgical, and experimental modalities for management of premature ejaculation

Research on the prevalence and management of premature ejaculation (PE) has historically been hampered by lack of clarity regarding what constitutes early ejaculation of clinical relevance; thus, inclusion criteria for studies on PE have often been heterogeneous. There has been a recent movement towards subclassification of early ejaculation into four separate conditions: (i) lifelong (or primary) PE, (ii)acquired (or secondary) PE, (iii)PE-like disorder (ejaculation-related distress in a patient whose ejaculatory latency is within the population-based reference range), and (iv) natural variable PE (occasional short ejaculatory latency in men who otherwise have normal ejaculatory function).The majority of clinical research to date has focused on the condition now most clearly understood as lifelong PE.
