Average penis size in Iran 🇮🇷
The published average stretched penile length for Iran is 11.58 cm (4.56 in), from Mehraban et al., 2007 (1,500 men). That's 1.35 cm below the worldwide average of 12.93 cm. Stretched length is the flaccid penis extended to full length and measured from the pubic bone to the tip, which is the measure urology studies report.

The study behind it
The figure comes from Mehraban et al., 2007, which measured 1,500 men. Method: measured by clinician.
This study didn't record a bone-pressed measurement, so it reads roughly a centimetre lower than a bone-pressed study of the same men would. Compare this row against a bone-pressed one and part of what you're seeing is the ruler.
A sample of 1,500 men puts this in the mid-range of the studies used here.
How it compares
Iran ranks #21 of the 24 countries in the game. That is 1.19 cm below the median of this list (12.77 cm).
Both of those comparisons are against a list of two dozen countries chosen by which studies exist, not by any sampling of the world. Treat the rank as a fact about this dataset rather than a fact about the planet.

When Iran came up
Iran has been the daily puzzle 3 times so far. Each of those days has its own archive page.
What this figure is not
It doesn't describe any individual man from Iran. The spread between individual men inside a single country runs several times larger than the gap between any two countries on this list, so a national average carries almost no information about a person.
Nor is it medical advice, or a benchmark to measure yourself against. If size is something you've been worrying about, the guide on what the pooled data actually shows is a more useful page than this one, and a doctor is more useful than either.

How to read this figure
- Every study on this subject has to solve one problem: who agreed to be measuredRecruitment decides the answer before anyone picks up a ruler. It is the largest source of disagreement between studies and the least discussed.
- There are five ways to measure, and they give five different numbersMost arguments about this subject are two people quoting different protocols at each other. What each one measures, and how far apart they land.
- A percentile is not a grade, and almost everyone reads it as oneNomograms are the most useful thing urology has produced on this subject and the most reliably misread. What the curve is actually telling you is narrower than that.
- How a number with no source becomes a fact everyone knowsThe country maps on this subject are mostly fiction, and they got there by a repeatable process. Once you can see the process, you cannot unsee it.
