We provide guidelines of penile length and circumference to assist in counseling patients considering penile augmentation.
We prospectively measured flaccid and erect penile dimensions in 80 physically normal men before and after pharmacological erection.
Mean flaccid length was 8.8 cm., stretched length 12.4 cm. and erect length 12.9 cm. Neither patient age nor size of the flaccid penis accurately predicted erectile length. Stretched length most closely correlated with erect length.
Only men with a flaccid length of less than 4 cm., or a stretched or erect length of less than 7.5 cm. should be considered candidates for penile lengthening.
我们提供阴茎长度和周长的指导方针，以协助为考虑阴茎增大的患者提供咨询。
我们前瞻性地测量了80名身体正常男性在药物勃起前后的疲软和勃起阴茎尺寸。
疲软平均长度为8.8厘米，拉伸长度为12.4厘米，勃起长度为12.9厘米。患者年龄和疲软阴茎大小均不能准确预测勃起长度。拉伸长度与勃起长度最密切相关。
只有疲软长度小于4厘米、或拉伸或勃起长度小于7.5厘米的男性才应被视为阴茎延长的候选者。
