Hierarchical clustering dendrogram shows similarity and dissimilarity with the ordering of cluster among the demographics, Clinical and hormonal profile in PE + DM patients. The dotted line represents the automatic truncation, leading to three clusters; Cluster I (Green): (CAG)n repeats, Total testosterone (TT), Intravaginal ejaculatory latency time (IELT), Premature ejaculation diagnostic tool (PEDT), prolactin, Oxytocin and Thyroid stimulating hormone (TSH) Cluster II (Red): Age, Erectile function (EF), International index of Erectile Dysfunction-15 (IIEF-15), Body mass index (BMI), sexual desire (SD) and overall satisfaction (OS) Cluster III (Blue): Beck’s Depression Inventory-II (BDI-II) and(GGC)n repeats
