- Finger Length Predicts Penis Length! -

JULY 2011 - KOREAN STUDY REPORTS:
FINGER LENGTH RATIO PREDICTS PENIS LENGTH!

So far 'body height' had been known as one of the few (significant) predictors for penis size. But Korean researchers have now present new evidence: a study among 144 Korean patients waiting for urological surgery has shown that the popular 'digit ratio' is a more reliable predictor for penis size that 'body height'!

Among the patients the ones with longer penises had finger lengths which are characterized by pointer fingers shorter than the ring fingers, according to a South Korean study published in the Asian Journal of Andrology. The researchers report:

"In the present study, patients with a lower digit ratio tended to have a longer stretched penile length. Stretched penile length was negatively associated with digit ratio. Based on this evidence, we suggest that digit ratio can predict adult penile size and that the effects of prenatal testosterone may in part explain the differences in adult penile length."

A REVIEW OF THE RESULTS:

The Korean study confirms a few earlier results (see the table below), e.g.: body height & index finger length correlate positive with penile length - though the result were only significant for body height (likewise result had been reported in a Greece anthropometry study in 2002 which did not include other fingers).

A couple of new results have been reported, e.g. the ring finger now appears to be a more significant predictor for penile length than the index finger. However, the ratio between the index finger vs. the ring finger - a.k.a. the 2D:4D digit ratio - has proven to be a more reliable predictor, even better than body height!

Finger length (& body height) predict penis length.

PROF. JOHN MANNING FORSAW THESE RESULTS!

Manning made in his second book 'The Finger Book' a few comments about the 2002 Greece study:

"... The measurements were used to determine the length of the shaft and the glans and the volume of the penis. All these variables were related to the length of the index finger. My guess is that they would have found the ring finger the strongest predictor, and that long ring fingers in relation to index fingers would be associated with longer penises." Professor John T. Manning.

The new results of the Korean study prove that professor Manning was right about that!

Professor John Manning - an evolutionary psychologist at the University of Central Lancashire, and an expert in the area - described:

"The digit ratio is a living fossil. It is a record of what the foetus was exposed to at a critical time for the development of many other things."

During the past decade multiple international studies have confirmed that a low 2D:4D finger length ratio may point to a rainbow of typically male characteristics, including: fast running speed, endurance running, and visuo-spatial abilities.


CONCLUSION + A FEW RECOMMENDATIONS:

The results so far have confirmed that penis size correlates negative with the 2D:4D finger ratio, and penis size correlates positive with body height.

Interestingly, penis size is also known to vary with ethnicity - and the same is true for digit ratio and body height.

But there are other hand factors that could very well correlate with all these variables: e.g. the fingerprint patterns!
