Abstract Purpose Normative male genital measurements are clinically useful and temporal changes would have important implications. The aim of the present study is to characterize the trend of worldwide penile length over time. Materials and Methods A systematic review and meta-analysis using papers from PubMed, Embase, and Cochrane Library from inception to April 2022 was performed. PRISMA guidelines were used for abstracting data and assessing data quality and validity. Pooled means and standard deviations for flaccid, stretched, and erect length were obtained. Subgroup analyses were performed by looking at differences in the region of origin, population type, and the decade of publication. Metaregression analyses were to adjusted for potential confounders. Results Seventy-five studies published between 1942 and 2021 were evaluated including data from 55,761 men. The pooled mean length estimates were flaccid length: 8.70 cm (95% CI, 8.16–9.23), stretched length: 12.93 cm (95% CI, 12.48–13.39), and erect length: 13.93 cm (95% CI, 13.20–14.65). All measurements showed variation by geographic region. Erect length increased significantly over time (QM=4.49, df=2, p=0.04) in several regions of the world and across all age groups, while no trends were identified in other penile size measurements. After adjusting for geographic region, subject age, and subject population; erect penile length increased 24% over the past 29 years. Conclusions The average erect penis length has increased over the past three decades across the world. Given the significant implications, attention to potential causes should be investigated.

Stanford study concludes that average penis size has increased 24% in 30 years - Researchers found that the average penis increased in size from 4.8 inches in 1992 to 6 inches in 2021. But in some regions, they shrank. - According to a new analysis, the average length of the erect male penis has risen by 24% between 1992 and 2021, from 12.27 cm (4.8 in) to 15.23 cm (6 in). - The genital gains were not shared equally across the world, however. Asian and European men experienced the greatest increase in penis size, while North American males' phalluses deflated slightly. - Researchers have offered a wide variety of explanations for lengthening penises, from earlier onset of puberty to the prevalence of porn.
