Male concern about whether penile size lives up to the desires of females seems to be largely misplaced.And unfounded worries about inadequacy are not helped by the fact that a man's own view of his penis automatically makes it look smaller to him than to someone else.studied the penis sizes of 80 "physically normal" men, measuring penile dimensions before and after drug-induced erections.After finding average sizes, they concluded: "Only men with a flaccid length of less than 4 centimeters [1.6 inches], or a stretched or erect length of less than 7.5 centimeters [3 inches] should be considered candidates for penile lengthening." In the The study also found that the size of a man's erect penis was not correlated with the size of his flaccid penis, meaning that men whose penises are different lengths when flaccid may have similarly sized erect penises.A number of different studies have sought to determine an average penis size.One published in 2001 took measurements of 3,300 young Italian men aged between 17 and 19 years.
In the study of 67 men complaining of a short penis, none was, in fact, found to be severely short.
It found the median average length of flaccid penises was 9 centimeters (3.5 inches), and the flaccid circumference (at the middle of the shaft) was 10 centimeters (3.9 inches).
Another study examined a different population, of 301 physically normal Indian men, and sought to compare its results with size findings in other countries.
Instead the study relied on the men's own measurements of penis size.
The reports may be considered fairly reliable, however, since the men were to be given condoms to match their self-reported measurements, meaning that any inaccuracy would have resulted in ill-fitting prophylactics.
There was a weak correlation between greater BMI and shorter erect penile length when this was measured from the skin over the pubic area, but not when the measurement was made from the bone to the tip.
