Validity of the premature ejaculation diagnostic tool and its association with International Index of Erectile Function ‑ 15 in patients with evidence-based-defined premature ejaculation.

The premature ejaculation diagnostic tool (PEDT) assesses premature ejaculation (PE). However, there is insufficient evidence about its validity in evidence-based‑ defined PE. The main aim of this study was to assess the validity of PEDT and its association with an international index of erectile function (IIEF-15) in Acquired premature ejaculation (APE) patients. A total of 50 men complaining of APE from Lahore institute of fertility and endocrinology, Hameed Latif Hospital, and 50 healthy control males without PE from a medical center were enrolled in this study. All individuals were asked to complete questionnaires including demographics, sexual history, and PEDT and IIEF‑ 15. The results of this research indicated men with APE showed higher PEDT scores (13.51 ± 3.04) and lower IIEF‑ 15 (39.45 ± 6.54) than men without PE (PEDT: 4.89 ± 2.14, IIEF‑ 15: 51.36 ± 2.36, P < 0.001 for both). Results also reported that a score of ≥ 8 indicated PE in Acquired premature ejaculation (APE) individuals by sensitivity and specificity analyses (sensitivity: 0.985; Specificity: 0.891). In APE men IIEF was negatively correlated to PEDT (adjust r = -0.311 P < 0.001) after adjusting for age. It was concluded that evidence-based‑ defined PE was diagnosed by PEDT. Moreover, PEDT was negatively related to IIEF-15 in APE men.
