They don't detail the sources of the studies, but I imagine the vast majority to be self-reported, which is enough to explain this supposed increase: it didn't increase, but having a big dick has become more and more the basic brag as internet developed.
> The initial search yielded 12,531 articles (PubMed: 1,975; Cochrane: 3,435; and Embase: 7,121). Duplicate articles appearing in multiple databases were excluded (n=8,022). After abstract screening, 7,850 papers were excluded. Of the remaining 172 papers, 97 were further excluded as they either did not report penis measurements (n=63), reported measurements after major pelvic surgeries (n=12), or *reported self-measurements (n=22).*
>In a study published Feb. 14 in The World Journal of Men's Health, Eisenberg and his colleagues compiled data from 75 studies, conducted between 1942 and 2021, that reported on the penile length of 55,761 men. The team found that the average erect penis length increased by 24% over 29 years, a trend they saw around the world.
you think that this many men over that period had complexes?
