<b><i>Purpose:</i></b> This study aimed to investigate the relationships between intravaginal ejaculatory latency time (IELT), severity of disease, and chronotype in lifelong premature ejaculation (PE). <b><i>Materials and Methods:</i></b> Evaluation was made of 114 males with PE and 103 healthy individuals, and comparisons were made of self-estimated IELT, Arabic Index of Premature Ejaculation (AIPE), Pittsburg Sleep Quality Index (PSQI), and Morningness-Eveningness Questionnaire (MEQ). <b><i>Results:</i></b> The frequency of morningness chronotype (78.1%) was significantly higher, and Morningness-Eveningness Questionnaire (MEQ) scores were negatively correlated with both IELT (<i>r</i> = −0.490, <i>p</i> < 0.001) and Arabic Index of Premature Ejaculation (AIPE) scores (<i>r</i> = −0.639, <i>p</i> < 0.001) in the PE group. MEQ scores significantly predicted IELT (<i>t</i> = −2.465, <i>p</i> = 0.015) and AIPE scores (<i>t</i> = −4.003, <i>p</i> = 0.000) in the PE group but not in the control group. <b><i>Conclusion:</i></b> It can be asserted that morningness chronotype is more common, and ejaculatory latency time and PE severity are associated with chronotype in males with PE.
