However, self-reported measurements are often unreliable.Ī 2019 study found that many males overestimate the size of their penis when self-reporting, especially if they have experienced sexual activity with another person. The participants submitted their own measurements and received condoms in exchange. In this study, the average dimensions for an erect penis were 14.2 cm (5.6 in) in length and 12.2 cm (4.8 in) in circumference. In 2014, researchers published findings from a study involving over 1,600 males in the United States. flaccid penis length: 9.16 cm (3.6 in) when stretched.The average measurements were as follows:

Ongoing research continues to produce similar findings about penis size.Ī 2014 review looked at measurements taken by healthcare professionals for up to 15,521 males aged 17 and over. People may refer to this as a buried penis, and surgery can resolve it.Įxperts note that these guidelines are still in use. Sometimes, an average-sized penis may appear small due because there is additional skin around it. Hormonal treatment or surgery can increase its size if a person wishes. A micropenis fulfills the same functions as an average-sized penis, but people may feel dissatisfied with its appearance. Some people are born with micropenis, when a penis is unusually small, usually due to hormonal or genetic factors. The researchers concluded: “Only men with a flaccid length of less than 4 cm (1.6 in), or a stretched or erect length of less than 7.5 cm (3 in) should be considered candidates for penile lengthening.” Micropenis and buried penis They also found no link between age and penis size. In other words, a penis may have different lengths when flaccid but similar lengths when erect.

The study also found that the size of a person’s erect penis did not correlate with their flaccid penis size. The researchers concluded that the average penis size was 8.8 cm (3.5 in) when flaccid and 12.9 cm (5.1 in) when erect. The study measured the penile dimensions of 80 males before and after drug-induced erections. In 1996, experts carried out a study that led to a set of guidelines for when a person may need surgery for penis enlargement.
