Penile anthropometry in North Indian children
Open accessAbstract
INTRODUCTION: Physicians frequently encounter questions by parents regarding the normal size of a child's penis. We evaluated normal variations of penile dimensions, correlation of penile length with height, weight, and body mass index (BMI) of boys and analyzed the differences in penile dimensions from those reported from other countries. MATERIALS AND METHODS: A cross-sectional study was conducted at our institution during October 2012-December 2012. A total of 250 subjects (birth to 10 years) were evaluated and divided into 10 groups with 1-year interval taking 25 children in each. Penile dimensions measured twice by a single observer with Vernier calipers included the length of flaccid penis fully stretched and diameters at mid-shaft and corona. Diameters were multiplied by pi (π = 3.14) to calculate circumferences. Mean, standard deviation, and range were calculated. Height, weight, and BMI were noted and statistically correlated with the penile length using the Pearson correlation coefficient. Data were compared with similar studies reported on other populations in the past and individually evaluated with every study using Student's t-test. RESULTS: The mean values for the penile length, mid-shaft circumference, and coronal circumference were 3.34, 3.05, 3.29 cm during infancy, 4.28, 3.86, 4.11 cm during 4-5 years, and 5.25, 4.78, 5.05 cm during 9-10 years, respectively. The penile length increased with advancing age in successive age groups, but it did not have a direct correlation with either height, weight, or BMI. Penile dimensions in North Indian children were found to be statistically smaller in comparison with most studies from other countries. CONCLUSION: We provide the normal range and variations of penile dimensions in North Indian children.

In neighboring India, many studies have been conducted to establish local nomograms for pediatric male external genitalia, some representing statewise populations.
“Pakistan lacks the sufficient reference data for this purpose, while on the other hand, in neighboring India, which shares close ethnic proximity, many studies have been conducted only for this sole purpose, some of which represent the statewise population highlighting the importance of locally derived nomograms [8, 15-19].”

The paper is an example of a regional Indian study: its conclusion reports normal penile dimensions in North Indian children. But the Discussion says the authors could find only one other study of Indian children, and the Introduction calls comparable Indian data sparse. That contradicts the attributed claim that many such studies had been conducted in India. (LLM, conf=0.87)
Checked by a reasoning model — may be wrong.
Experimental — accuracy not yet measuredStretched penile length and penile circumference demonstrated gradual progression from infancy through late childhood, supporting similar findings in other studies.
“Stretched penile length and penile circumference demonstrated gradual progression from infancy through late childhood supporting the similar finding in other studies [15, 22].”

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.
