(267) Penile Length and Circumference in Vietnamese Men

Abstract

Abstract Introduction Penile size has long been an important fixation in men's lives. Establishing what the normal size of the penis is very important to have a yardstick for men, which is a challenge and depends on the culture, race, and form of measurement applied. Objective To evaluate the size of the penis in flaccidity, erection, and stretch of Vietnamese men. Methods A total of 259 men who visited the Andrology and Fertility Hospital of Hanoi, VietNam were involved in the study between October 2022 and April 2023. Penile measurements (flaccid, erect length/circumference, stretched length) were predominantly taken by 1 investigator using a tape measure and the same measurement technique. All statistical analyses were completed using STATA 17.0. Statistical analysis was performed with the Spearman correlation as tested by the Kolmogorov–Smirnov test (p<0.05). Results The mean age of 259 patients was 29,24 (range: 15–48). The mean penile lengths were: flaccid length 9.21 cm (SD 1.71 cm), flaccid circumference at the middle of the shaft 8.25 cm (SD 0.96 cm), erect length 13.22 (SD 1.46cm), erect circumference at the middle of the shaft 10.42 cm (SD 0.94 cm), and stretched length 12.47 cm (SD 1.61 cm). The mean testicular volume was 12.47 mL (SD 6.37 mL) and 12.65 (SD 4.03 mL) for the left and right testicles, respectively. Stretched length is most closely correlated with erect length with r=0.68. We also observed that the testicular volume, erect length was a significant inverse correlation with age, which ranged from r = -0.14 to -0.21. Conclusions The results of this study help to establish a reference range for male genital size in Vietnam, which should be helpful for urologists and andrologist in counseling patient Disclosure No.
