The DSM-IV diagnostic criteria for premature ejaculation remain to be investigated by a clinical study. A prospective study was therefore conducted to investigate the DSM-IV definition and to provide an empirical operationalization of premature ejaculation. In this study 140 men suffering from lifelong premature ejaculation were interviewed separately from(More)
