Human penises vary in size on a number of measures, including length and circumference when flaccid and erect. Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of arousal , time of day, room temperature, and frequency of sexual activity. Compared to other primates, including large examples such as the gorilla, the human penis is thickest, both in absolute terms and relative to the rest of the body. Measurements vary, with studies that rely on self-measurement reporting a significantly higher average than those with a health professional measuring. As of [update] , a systematic review of 15, men, and the best research to date on the topic, as the subjects were measured by health professionals, rather than self-measured, has concluded that the average length of an erect human penis is
Now, a new study could assuage such worries with what may be the most accurate penis-size measurements to date. So when Veale and his team set out to settle the score on penile proportions, they decided to compile data from clinicians who followed a standardized measuring procedure. Published today in the British Journal of Urology International , their new study synthesizes data from 17 previous academic papers that included measurements from a total of 15, men from around the world. The data enabled the researchers to calculate averages and model the estimated distribution of penile dimensions across humanity. The corresponding girth measurements are 9.
Respondents had to guess the length of the average erect penis and also answer what an ideal penis is, length-wise. Of the 2, respondents , between the ages of 18 and 75, 1, identified as male and identified as female. Almost half of the survey pool was from the United States 1, while the rest lived in nine different countries throughout Europe. The survey did not account for sexual identity or ethnicity of respondents.
The average girth is 3. Girth is the circumference of the penis at its widest section. The BJUI research used data from 17 studies, and the study participants totaled more than 15, men.
