Penile size in adult men—recommendations for clinical and research measurements
Abstract
Data regarding the size of the adult penis is of great importance to both clinicians and researchers. Currently, there is no consensus regarding the preferred method for the evaluation of penile size. Various and conflicting methods are reported in the literature. We review the data on measurement methods of the flaccid, stretched, and erected penis with the aim of constructing a recommendation for best practice. A systematic search for articles on penile length and girth measurement techniques was performed using PubMed, Google Scholar, and Cochran Library. Only peer-reviewed articles published in English before August 2018 were reviewed. All authors evaluated the methods and results sections presented in each publication. Relevant, demonstrative publications are reported in this review. We did not find definitive evidence favoring one measuring method over the other. Therefore, we advocate the use of our recommendations for penile size measurement in future publications.

The lack of standardization for measuring penis size in different situations may have led to a systematic bias.
“A serious limitation to our findings is the lack of standardization for measuring penis size in different situations,4 which may have led to a systematic bias.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
