^*P<0.05 (comparison between nature and GA state); ^aMann–Whitney U test; ^bStudent’s t-test. The data of abnormal distributions presented as median (IQR) was analyzed by Mann– Whitney U test with a significance level alpha=0.05. The data of normal distributions presented as mean±s.d. was analyzed by Student’s t-test with a significance level alpha=0.05. PE: premature ejaculation; BMI: body mass index; IIEF-5: International Index of Erectile Dysfunction-5; IELT: intravaginal ejaculatory latency time; PEDT: premature ejaculation diagnostic tool; PEP: premature ejaculation profile; PSSR-Lat: latency of penile sympathetic skin response; DNSEP-Lat: latency of dorsal nerve sensory-evoked potential; GA: general anesthesia; GPSEP-Lat: latency of glans penis sensory-evoked potential; s.d.: standard deviation; IQR: interquartile range
