Study concludes that average penis size increased by 24% over 30 years



Scientists note that from 1992 to 2021 the average penis length increased by about 3 cm. But this whole shift in development is disturbing, they note.

New Findings from an International Research Team Led by a Urologist Stanford University refers to the average size of erect male penis A 24% increase between 1992 and 2021.

Their analysis was published in the journal World Journal of Men’s Healthreviewed, tallied, and tabulated the results of 75 studies conducted worldwide over the past decades in which erect penis size in men was measured in the laboratory.

Data from 55,761 men aged 18 years and older were included. Adjusting for geographic region, age, and population of participants, the authors found that the average erect penis length in adults increased from 5 inches in 1992 to 6 inches in 2021.

However, these increases are not evenly spread across the globe. Asian and European men had the greatest increase in penis size, while North American men experienced a slight decrease.

What’s behind this disturbing statistic?

The lead author of the study, Dr. Michael Eisenberg, professor of urology at Stanford University, expressed concern about the global trend in question.

“Global changes in development are concerning because our reproductive system is one of the most important parts of human biology. It means that something important is happening in

he added that “Several factors may be involved, including exposure to chemicals such as pesticides and hygiene products that interact with our hormonal system.

As they wrote in their article, Eisenberg and his co-authors also speculate that the trend toward early onset of puberty in boys also influences penis enlargement.

There is another, simpler and gentler explanation. Nutrition has improved in much of Europe and Asia in recent decades, and people are growing taller and taller.

On the other hand, North American men “suffer” from overeating.

more research is needed

For Eisenberg, the next big step in research is to look at other groups of patients (such as children and adolescents) to see if similar changes occur.

“Additionally, with detailed data on lifestyle factors and environmental exposures, we can try to understand why this is happening,” he says.
