Proposals or findings for a new approach about how to define and diagnose premature ejaculation.

PURPOSE

To review and present the proposals or findings for a new approach about how to define and diagnose premature ejaculation (PE).

MATERIALS AND METHODS

Using Medline to search for international peer reviewed manuscripts published from 1996 to 2004 about the definition and diagnosis of PE.

RESULTS

PE, to date, has not a universally agreed definition and diagnostic criterion. Many definitions are partial, subjective and nonspecific. An ideal definition or diagnostic criterion should consist of intravaginal ejaculatory latency time (IELT), the ability to control over ejaculation, the extent of male sexual satisfaction, the extent of female sexual satisfaction, the frequency of female sexual partner reaching orgasm and the extent of psychological and pathological factors. Therefore, the Chinese Index of Premature Ejaculation (CIPE) seems an ideal tool and criterion used to diagnose PE due to including all the elements above. In the majority of cases, PE is the result of a mix of psychogenic, physiological and organic factors. So, besides some routine tests such as urine routine test, endocrine hormone assay, psychosexual counseling, couple evaluation and physical examination, prostate examination, serum leptin assay, semen magnesium assessment and glans hypersensitivity measurement, are suggested to be performed in the diagnosis of PE. Although elucidated by two clinical trials and further confirmed, serum leptin assay seems a promising and objective marker to diagnose PE because it is related to the serotonergic system whose disorder has been confirmed to contribute to the etiology of PE.

CONCLUSION

None of these definitions and diagnoses has been accepted as a universal agreement of PE. CIPE seems an ideal tool and criterion used to diagnose PE and leptin maybe become a promising and objective marker for PE.
