A new report has finally revealed the “definitive” length of an average penis.
Scientists have revealed the normal length of a trouser snake when erect is 5.2inches (13.12cm) and 3.6inches (9.16cm) when flaccid.
The average erect circumference is 4.6 inches (11.66 cm) and 3.7 inches (9.31 cm) when flaccid.
More than 15,521 men had their genitals measured across 17 different studies.
Lead author Dr David Veale from the Institute of Psychiatry, Psychology and Neuroscience (IoPPN), King’s College London and South London and Maudsley NHS Foundation Trust, told MailOnline: ‘Men compare themselves in locker rooms and with pornography on the internet and believe they are inferior.
‘Some men have been teased by sexual partners about their length.
‘There are lots of men who might be worried – and we think reassuring men they are in the normal range will help.
‘We will also use the graphs to examine the discrepancy between what a man believes to be their position on the graph and their actual position, or what they think they should be.
The research also found there was a small correlation between the erect length of a penis and a man’s height.’
Here are the official penis measuring guidelines from the NHS website:
‘At some stage, most boys get out a ruler or a tape measure to find out how long their penis is.
‘Dr Delvin says there’s little point in doing this when the penis is limp because the length of a flaccid penis can vary a lot, for example depending on how cold the room is.
‘To get a precise measurement, do it when you have an erection. Take the measurement from the base of the penis on the side nearer to the tummy, up to the tip, where the hole is.’
