A new study published last week in the Journal of Sexual Medicine says the average American man's penis is 14.2 centimeters long when erect.

The new findings, from a survey of over 1600 men, are relatively consistent with prior research on self-reported penis size. But can we rely on the stats?

"Although many men may wish their penis were larger and may expend significant effort toward penile enlargement, this does not necessarily mean that men overreport their penile size to researchers," the researchers wrote.

Men were asked to measure their penis's length and girth when erect, and to submit their individual data online to researchers.

Dr Herbenick, the Indiana University expert who conducted the study, told Psychology Today that she trusted men to give accurate measurements - as the study was part of broader research into condom sizes. 

"If they reported a bigger-than-reality size to us, they would get a baggier condom.

"If they reported a smaller-than-reality size to us, the condom would be too tight," she added.

Penis size has been the subject of dozens of studies, as well as countless urban legends, myths and spam emails.

Also, men have to deal with images portraying the 'ideal' man just as much as women.

The findings of the research showed that penises come in all shapes and sizes: the smallest erect penis in the study was about 4cm long, and the largest was 26 cm long. The average penile girth was about 12.2cm.

Scientists also found that the size of the erect penis varied depending on how it was achieved: purely mental stimulation proved to provide the least growth. 

Dr Herbenick told the magazine that she would like to see more research conducted into the size of female genitalia to encourage women to think more positively about their bodies.
