Chronotype (or circadian preference) has previously been shown to be associated with sexual attitudes and behaviors and is an important factor affecting sexual satisfaction. The fact that some neurobiological variables, which are thought to have a role in ejaculation physiology, are also effective in the processes of sleep and the regulation of circadian rhythm, and evidence supporting the relationship between circadian preferences and sexual desire and sexual behavior; suggests that ejaculation disorders may be related to circadian preference. The aim of the present study was to investigate the relationship between intravaginal ejaculatory latency time (IELT), severity of disease and chronotype in lifelong PE.
After being informed about the study, all patients who gave written informed consent were questioned and diagnosed as lifelong PE according to the definition of International Society of sexual medicine (ISSM) by an experienced urologist. Since erctile dysfunction (ED) may accompany PE, the presence of ED symptoms was evaluated by the International Index of Erectile Function (IIEF-5), and those with IIEF-5 score \<22 were excluded from the study. Age- and sex-matched control cases without lifelong PE were selected randomly among cases attending the hospital for a checkup procedure. A total of 114 patients with PE and 103 control subjects with similar sociodemographic characteristics were included in the study. A detailed medical and sexual history was taken, which included self-estimated intravaginal ejaculatory latency time (IELT), by an experienced sexual therapist. Moreover, Arabic Index of Premature Ejaculation (AIPE), Pittsburgh Sleep Quality Index (PSQI) and Morningness-Eveningness Questionnaire (MEQ) were administered to all participants.
106 studies on the registry are indexed under Premature Ejaculation; 17 are open to participants now.
This study's enrollment of 217 is below the median of 600 across 17 observational studies indexed under Premature Ejaculation.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Premature ejaculation group
Diagnostic Test: Intravaginal ejaculatory latency time (IELT), Arabic Index of Premature Ejaculation (AIPE), Morningness-Eveningness Questionnaire (MEQ)
Control group (Healthy subjects)
Diagnostic Test: Intravaginal ejaculatory latency time (IELT), Arabic Index of Premature Ejaculation (AIPE), Morningness-Eveningness Questionnaire (MEQ)
Self-estimated intravaginal ejaculatory latency time IELT is defined as the time between the onset of vaginal intromission and the onset of intravaginal ejaculation. In the present research, self-estimated IELT duration was obtained as a result of interviews with the participants. Moreover, Arabic Index of Premature Ejaculation (AIPE), International Index of Erectile Function (IIEF-5), Pittsburgh Sleep Quality Index (PSQI) and Morningness-Eveningness Questionnaire (MEQ) were administered to all participants.
MEQ scores
MEQ is a measurement tool developed to measure the morning and evening sleep cycle associated with circadian rhythm (Horne \& Östberg, 1976). It consists of 19 self-reported likert-type items and has a rating range from 16 to 86. Higher scores in the MEQ refer to morningness chronotype, and lower scores refer to eveningness chronotype. In the Turkish adaptation study of MEQ, three different categories of circadian rhythm were defined as; 59-86 points "morningness type", 42-58 points "intermediate type", 16-41 points "eveningness type"
