A look at the relative length of a man's index and ring fingers might be a good predictor of the length of his penis.

Researchers from South Korea compared the digit ratios of 144 Korean men aged 20 and older who were being treated for urological surgery. Researchers measured the index and ring fingers of each man's right hand and compared the ratio to the length of each man's fully stretched, flaccid penis (the latter data obtained under anesthesia).
It was found that the ratio between the second and fourth digits on a man's right hand seemed to correlate to the length of his flaccid and stretched penis, with a lower index-to-ring finger length ratio indicating a longer penis. The key to this relationship may lie in the womb. The researchers noted that penile length and the second-to-fourth digit ratio in males are thought to be fixed early in development. In each case, this involves a common set of genes that regulate prenatal hormones (including testosterone) to influence both limb development and the development of the urogenital system. During the fetal period, high concentrations of testosterone lead to high testicular activity, resulting in a lower digit ratio. In the present study, patients with a lower digit ratio tended to have a longer stretched penile length. The researchers added that the length of the stretched and flaccid penis does show a strong correlation with an erect penile length.
Most men have index fingers that are shorter (low ratio) than their ring fingers, while most women's index fingers are the same size or longer (high ratio) than their ring fingers. Research has shown, however, that lesbians and female-to-male transgendered people are more likely to have more "male" ratios.
The above study results provide convincing support for a relationship between digit ratio and penile length. Digit ratio is non-invasive and easy to measure, yet may provide clues about an individual's prenatal history. Thus, combined with other information, digit ratio offers the potential for clinical usefulness. The findings might have real value for research into clinical conditions linked to developmental issues in men.
