Abstract
INTRODUCTION: Arousal to ejaculation latency time interval (AETI) and erection to ejaculation latency time interval (EETI) are new tools used to measure ejaculatory latency time (ET). Unlike intravaginal ejaculation latency time (IELT), they are applicable for sexual activities other than penovaginal intercourse and do not require penetration. We assessed the distribution and relation between AETI, EETI, and IELT in Indian men. METHODS: Voluntary participation was sought to recruit subjects reporting premature ejaculation (PE) and normal ejaculation. Those able to record the ETs correctly were then asked to record their ETs for two subsequent sexual events. RESULTS: A total of 26 subjects (13 - normal and 13 - PE) were able to complete the study. The mean age of the participants was 29.85 ± 4.8 years, with no difference seen between the two groups. The mean AETI, EETI, and IELT were 817 ± 592.016 s, 726 ± 566.346 s, and 582 ± 450.859 s, respectively, in normal subjects. PE subjects had significantly lesser mean ETs, AETI 80.62 ± 24.74 s, EETI 53.46 ± 25.441 s, and IELT 21 ± 14.785 s. Regression analysis found that 131.67 s of AETI and 99.58 s of EETI were equivalent to 60 s of IELT. CONCLUSIONS: AETI and EETI have positively skewed distribution similar to IELT. Premature ejaculators had less difference between AETI and EETI, suggesting that sexual cycle gets completed immediately following arousal in these subjects causing PE.
