An online survey result reveals that the average length of an American penis is 5.6 inches long when erected. About 1, 1661 male participated in the said survey.
Debby Herbenick, lead author of the study and a human sexuality professional from the Indiana University, and her colleagues initiated the study to identify how men perform self-measurement and their behavior after finding out the result linked to their erected penis measurement. They also wanted to know if men would presumably report the real measurement of their penises.
The researchers used an online site to generate the statistics and responses they need for this study in which 1,661 men willingly participated in the experiment masked in a survey. The respondents were not directly asked about the length of their penis but rather if a regular-sized condom matches the actual size and length of their manhood when erected. They were asked to provide descriptions though to support their responses.
The length of a regular sized condom is between 7 inches and 7.9 inches according to a condom size chart.
After closing the survey, the researchers tallied the responses of the participants. They found out that the average length of an erected penis is 14.15 cm or 5.6 inches. The shortest registered was 2.66 cm or 1.05 inch while the longest was 24 cm or 10.2 inches. The average circumference was 12.23 cm or 4.8 inches. The smallest was 3 cm or 1.2 inch while the largest was 19 cm or 7.5 inches.
The survey also revealed that most men did the measurement on their own using hand stimulation to achieve erection. Others asked help from their partners or friends to reach erection. Those with larger circumference are more likely to be aroused through oral sex while the rest can be aroused by mere fantasy.
The study was published in the July issue of the Journal of Sexual Medicine.
