Researchers from Stanford University found that the average erect penis has increased from 4.8 inches erect to 6 inches over the past 30 years, but that may not be a good thing.
Articles were excluded if they were based on a self-measurement and if they reported measurements done after major pelvic surgery. Abstracts and meeting reports were excluded from the analysis.

yeah :deeper-sadness:
No
What about studies where participants were aware their penis would be measured?
Small pp dudes are less likely to respond to advertisements for such studies.
How would you even get a true representative sample, military physicals or something?
mandatory penis inspection day
For erect lengths, that's probably better.
For flaccid lengths, coroner's reports.
