Objective

Intravaginal ejaculatory latency time (IELT) is an important tool for the assessment of premature ejaculation (PE), not only in diagnosis, but also in clinical trials for PE. The IELT can be measured by stopwatch which it is not practical for patients to provide in clinical practice, or can be measured by self-estimate, which is different from stopwatch-measured IELT (SW-IELT). In the current analysis, we focused Number of Intravaginal thrusts before ejaculation (NITBE), which was mentioned two decades ago but not widely used, to assess the influence of those measures in identifying PE.

Methods

Data were from half a year, single center, observational study of men with (204) and without (106) premature ejaculation (diagnosed using complains from human subjects combined with questionnaire of Chinese Index of Premature Ejaculation (CIPE)), as well as their female partners. Estimated IELT (E-IELT), SW-IELT and NITBE, age, and responses to multiple item of CIPE were evaluated with stepwise logistic regression analysis.
