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.
