New Tools to Measure Ejaculatory Latency-Arousal to Ejaculation Time Interval and Erection to Ejaculation Time Interval: A Pilot Study.

OBJECTIVE: The present study aimed to evaluate the proposed novel tools, namely, arousal to ejaculation time interval (AETI) and erection to ejaculation time interval (EETI), and to measure ejaculatory latency during different types of sexual encounters in a pilot study.

MATERIALS AND METHODS: The study period was from September 2016 to December 2016. After obtaining informed consent and institutional review board approval, the medical practitioners without any comorbidity and who volunteered to participate were asked to report their self-assessed AETI and EETI during a sexual activity. They were also asked to opine as to whether they consider themselves as normal ejaculators, delayed ejaculators, or premature ejaculators. Statistical data including mean, standard deviation, and P value were obtained.

RESULTS: The sample size was 60 with a mean age of 48.9 ± 10.8 years. A total of 48 participants reported themselves as normal. Their mean AETIs were 624.8 ± 83.6 seconds, 700 ± 79.1 seconds, and 420 ± 57.7 seconds, and their mean EETIs were 355 ± 82.6 seconds, 442.5 ± 46.6 seconds, and 240 ± 38.6 seconds during heterosexual vaginal intercourse, masturbation, and oral sex, respectively. Twelve participants reported premature ejaculation, and their mean AETIs were 122 ± 11.6 seconds, 73.33 ± 11.2 seconds, and 74 ± 12.3 seconds, and their mean EETIs were 106.7 ± 21.6 seconds, 70 ± 13.7 seconds, and 60 ± 11.8 seconds during heterosexual vaginal intercourse, masturbation, and oral sex, respectively. None of the participants reported themselves as delayed ejaculators. The differences between the means were statistically significant (P ≤.0001).

CONCLUSION: AETI and EETI can be used to measure ejaculatory latency in different types of sexual encounters.
