With great interest, we read the article by Vakalopoulos et al. (2011), which evaluated the prevalence of ejaculatory disorders in Greek urban men. After reflection, there are several concerns that deserve further discussion and explanation. First, the title is inaccurate. The authors use the term ‘ejaculatory disorders’, but should consider using the term ‘early ejaculation disorders’ (EED), as ejaculatory disorder is too broad in respect to this article. ‘Ejaculatory disorders’ encompasses not only EED, but also anejaculation, delayed ejaculation, retrograde ejaculation and painful ejaculation (Colpi et al., 2004). The authors state that the definition of the prevalence of lifelong PE according to the International Society for Sexual Medicine has not yet been determined. However, in a recent peer-reviewed publication, the prevalence of lifelong PE was noted to be 2.3% (Serefoglu et al., 2011), which also matches the findings of Waldinger (2008) who estimated the prevalence at 2–5%. In the present study, the authors determine the prevalence of lifelong PE to be 17.7%, which is much higher than expected and determined by other recent research. Further clarification is needed to explain this discrepancy. In conclusion, we have a number of questions that the authors should address to help the readers interpret the data. What differentiates lifelong PE from the other PE syndromes? Similarly, what were the criteria for defining EED? What were the ranges of intravaginal ejaculation latency times (IELT) for EED and lifelong PE?
