Question:
What is the average penis length for a guy before his penis begins to grow?
Pretty self explanatory title...
Answers:
Considering that the penis begins to grow at around 12 weeks after conception, it is pretty small, less than 1 mm.
If you mean at birth, it is approximately 4 cm or 1.6 inches and grows to an average of 6 cm (2.4 in) before the onset of puberty.
