A review of the medical literature published in BJU International by Dr David Veale of King's College London found 17 studies with up to 15,521 males who underwent penis size measurements by health professionals. Veale found that:

  • the average length of a flaccid penis was 9.16 cm;
  • the average length of a flaccid stretched penis was 13.24 cm;
