A new study has revealed the “ideal” shape and length of the penis.
The researchers asked 1,029 men and women to examine 14 computer-generated images of erect, circumcised penises.
Participants evaluated one aspect of the penis in each image, such as its shaft or cylindrical structure from base to head, or the head of the penis.
The findings allowed researchers at the University of California, Riverside to build the “perfect” penis.

In the survey, participants were shown a pair of images in which an aspect of the penis had been digitally altered, such as the length of the shaft or the shape of the head.
They were asked to indicate which they preferred, and the researchers analyzed the responses to reveal which feature was the “best” and construct the ideal penis.
This was repeated seven times for the participants, who had an average age of 30 to 39 years, to evaluate seven different penile characteristics.
Overall, most participants said they preferred a penis with a longer shaft, a more prominent corona (the rounded ridge at the base of the penis head), and a slightly smaller head.
When viewing the penis from the side, participants also said they preferred a head that sloped downward from the end of the shaft and had a slight angle at its base.
On average, participants said they liked the same width throughout the organ rather than a penis that got larger at the base.
The researchers did not ask participants to rate overall penis length to establish which was “best,” but previous studies concluded that the ideal length was 6.3 inches when erect.
For comparison, a meta-analysis A study involving more than a thousand men (mainly in Europe, America and Asia) suggested that the average erect penis length was 5.1 to 5.5 inches.
The researchers also found variations in penis preferences by age and sexual orientation.
They highlighted that their results suggested that preference for the penis was intensely personal (stock).
Older adults were 25 percent less likely to prefer a larger ridge at the base of the penis, compared to younger individuals, and 18.4 percent less likely to prefer a head with an angle at its base.
Heterosexual adults, who were the majority in the study, were 65 percent more likely to prefer a larger crown.
The results also showed significant differences in penis preferences between medical professionals, who made up half of the participants, and others, which the scientists said could be related to their training experience.
The researchers said they conducted the study to provide guidance to doctors who reconstruct penises after catastrophic injuries.
Summing up the results, Dr. Justin Cordero, a urologist, and others wrote in the study: “Ideal phallic aesthetics vary by individual, and there were statistically significant preferences by age…and sexual orientation.”
“This study can serve as a guide on phalloplasties for gender-affirming patients and surgeons.”

For the study, participants were recruited through surveys distributed on Craigslist, Amazon, and Reddit.
Of the participants, the majority (539 people) were heterosexual, but the remaining 370 were homosexual, bisexual or of another sexuality.
By gender, the majority of participants were men, 440 people, or women, 334 people.
The document also included 92 adults who were transgender men (10 percent of the total) and 25 transgender women (three percent of the total).
