A statistical analysis that combines the results of multiple studies to draw more general conclusions.
A clinician‑measured global estimate for (circumference) centers around 11.66 cm (4.59 inches), based on large meta‑analyses and systematic reviews that prioritized measurements taken by health profes...
Three large clinician‑measured meta‑analyses now provide the best aggregated estimates of human penile dimensions: a global nomogram/meta‑analysis of up to 15,521 men that produced clinical reference ...
A penis measuring 6.7 inches in erect length and 5.25 inches in girth is larger than the averages reported in scientific measurement studies: typical erect length is about 5.1–5.5 inches and typical e...
Major scientific efforts to define “average” penile size rely on cross-sectional measurements—erect, flaccid stretched, and flaccid—taken either by clinicians or self-reported; studies that used clini...
Accurate clinical measurement for diagnosing macropenis relies on standardized stretched penile length (SPL) taken from the pubic bone to the distal tip of the glans with attention to technique, obser...
has generally pooled clinic-based and volunteer studies using varied techniques—flaccid, stretched, or erect—often measured with a ruler by clinicians or by participants, and then to produce populatio...
A large 2023 systematic review and meta‑analysis pooled data from 75 studies and roughly 55,000 men and reported in mean erect penile length — an increase of about 24% from 1992 to 2021 after adjustme...
Clinical and self-reported measurements of penile length diverge in predictable ways: self-reports tend to be larger on average due to social desirability and perceptual bias, while clinician-measured...
Clinician‑measured studies of penile length and girth exist across dozens of countries and several large pooled reviews, which typically report means (with SD/SE) rather than medians; a 2025 WHO‑regio...
