Table 2 Clinical and sexual parameters of subjects with PE + DM and normal group based on Androgen receptor (CAG)n repeats

From: Longer trinucleotide repeats of androgen receptor are associated with higher testosterone and low oxytocin levels in diabetic premature ejaculatory dysfunction patients

Subjects with PE + DM n = 250 Control subjects n = 150
  CAG Long stretches ( ≥ 26) n = 108 CAG Medium stretches (22–25) n = 88 CAG short stretches ( ≤ 21) n = 54 Kruskal-Wallis = P* CAG Long stretches ( ≥ 26) n = 43 CAG Medium stretches (22–25) n = 85 CAG short stretches ( ≤ 21) n = 22

  1. PE Premature Ejaculatory dysfunction; DM Diabetes mellitus type II BMI Body mass index; TSH Thyroid stimulating hormone; PEDT Premature ejaculation diagnostic tool; IELT Intravaginal ejaculatory latency time; BDI-II Beck’s Depression Inventory II; EF Erectile function; OR Orgasmic function; SD Sexual desire; OS Overall satisfaction; IS Intercourse satisfaction; IIEF-15 International index of Erectile Dysfunction-15. Kruskal-Wallis test was used to assess the distribution of values across the subgroups based on the length of CAG repeats
  2. Data are presented as median (interquartile range). Significant differences among PE + DM subgroups are shown in bold (P < 0.001). # (P < 0.05) shows that a result is significantly different from only one of the other PE + DM subgroups. *p < 0.0167 (Kruskal-Wallis/two tailed test with Bonferroni correction) means differences between PE + DM subgroups and entire control group. No statistical difference was found between 3 subgroups (the short, medium, and long CAG) of controls
