Penile length of men attending urology outpatient clinic in Southwest Nigeria

Penile length varies worldwide. It is necessary to determine penile length in our region to enable adequate counselling on normal length and reduce avoidable anxiety. Two hundred and seventy-one men were recruited with 97 men in group I and 174 men in group II. Mean ages were 38.4 ± 6.9 (21-50) years and 68 ± 9.1 (51-98) years. In group I, the mean flaccid penile length (FPL)-I and stretched penile length (SPL)-I were 9.8± 2.7 and 10.6± 2.2, mean height 1.7±0.07m and body mass index (BMI) 24.1±3.1 kg/m(2). While in group II, mean FPL-II and SPL-II were 13.0± 2.9 and 14.1 ± 2.1, mean height was 1.69± 0.07m and BMI 24.3± 3.2 kg/m(2). There were positive correlations between the SPL-I and heights in group I; (r=0.305, p<0.002); height and FPL-I (r = 0.218, P<0.032). Similarly, in group II positive correlations of FPL-II and SPL-II with height; r = 0.166 P<0.028 and r = 0.183, P<0.015. There was negative correlation SPL-II and BMI-II r-0.224, p<0.003. FLR-II and BMI-II, -0.157, p<0.039. In conclusion, Flaccid and stretched penile length of men < 50 years was smaller than those > 50 years. In both age groups, flaccid and stretched penile lengths correlated with height. In group II, penile lengths correlated negatively with BMI.
