Penis Size

Human penis size is the measured length and width of the human penis. The most accurate measurement of the human penis comes from several measurements at different times, as there is natural variability in size due to arousal level, time of day, room temperature, frequency of sexual activity, and unreliability of the measurement methods.
Results vary, with studies that rely on self-measurement reporting a significantly higher average than those with staff measuring, but a mean human penis is approximately 12.9–15.0 cm (5.1–5.9 in) in length.
Fear of shrinking of the penis in folklore have led to a type of mass hysteria called penis panic. Marketers of penis enlargement products exploit fears of inadequacy, but there is no consensus in the scientific community of any non-surgical technique that permanently increases either the thickness or length of the erect penis that already falls into the normal range.
Penis girth is the measurement of the circumference of the completely erect penis. It is variously quoted as an average of three measurements: just below the glans penis, in the middle of the shaft, and at the base.
An adult penis with an erect length of less than 7 cm or just over 2 inches but otherwise formed normally is referred to in a medical context as having the micropenis condition. The condition affects 0.6% of men.
