We will present you with facts from all the scientific studies done on penis size so that once you have finished reading this article, you will feel content that you have the most accurate answer to the question. And perhaps you will be reassured about your own size or that of your partner's penis. Published findings are often introduced with background information on men's widespread anxieties about whether or not their penises are big enough, and if sexual partners are going to be satisfied.

So what is the truth? Given the ubiquity of free, easily accessible internet pornography, and the rise in aggressive marketing by companies promising a bigger penis through the use of extenders and enlargers, it is easy to see why the truth about male genital length and girth might have become obscured. Perhaps it is no surprise, then, that researchers consistently find that men have heightened anxieties about their manhoods. Here are some key points about the average penis size.

More detail and supporting information is in the main article. Perhaps the best gauge of what is considered to be a small penis is given by the threshold used by doctors for when penile augmentation may be considered.

Researchers publishing in the Journal of Urology studied the penis sizes of 80 "physically normal" men, measuring penile dimensions before and after drug-induced erections.

After finding average sizes, they concluded :. In the Journal of Urology study, researchers found the following among the group of 80 men:. The study also found that the size of a man's erect penis was not correlated with the size of his flaccid penis.

This means that men whose penises are different lengths when flaccid may have similarly sized erect penises. There was also no relationship between the men's ages and their penis sizes. The finding on how much the penis length can 'grow' — on whether you are a 'shower' or a 'grower' — was further supported by a study of Turkish men, in which "flaccid length had little importance in determining erect penile length.

The research to determine average penis size includes a study published in January that examined over 1, American men, although it did not take independent physical measurements. Instead, the study relied on the men's own measurements of penis size. The reports may be considered fairly reliable, however, since the men were to be given condoms to match their self-reported measurements, meaning that any inaccuracy would have resulted in ill-fitting prophylactics.

The researchers said the self-reported erect penile dimensions were consistent with findings from other studies. Their study added the finding that the precise dimensions of an erection can be influenced by the mode of getting aroused, such as whether a man uses hand stimulation. To measure penis length, press a ruler into the groin and measure from the base of the penis to the tip.

Male concern about whether penile size lives up to the desires of females seems to be largely misplaced. And unfounded worries about inadequacy are not helped by the fact that a man's own view of his penis automatically makes it look smaller to him than to someone else. Looking down at the penis from above makes it appear smaller, compared with how it looks straight on, or from the side.

Seeing one's own penis from this perspective and perhaps comparing it with other men's appendages from a different perspective, may, therefore, reinforce false ideas of penis size. But do women have a more reliable perception? One study, published in the British Journal of Urology International , suggested that while the majority of women, some 85 percent , were satisfied with the size and proportion of their partner's penis, men were less sure of themselves.

Almost half of men in the study 45 percent believed they had a small penis, yet the researchers reported that small penis size was actually rare. Some women answered questionnaires in another study, which found that while they attached some importance to penis size, it was only of "substantial" importance to a "clear minority" of the women. While most of men's worries about penis size centre on the length, women are more interested in width, according to one study.

The study of 50 sexually active undergraduate women reported that for a large majority — 9 out of 10 of the women — penis width was more important to sexual satisfaction than penis length. A study published in the open-access journal PLOS ONE in November took the novel approach of asking women to show their penis size preferences with the use of 3D printed models of 33 different dimensions. The sizes had been printed across a range from 4 inches to 8.

The 3D-printed shafts were in blue plastic so as not to suggest any particular race that might prejudice the women's ideas of average size. The 75 women indicating size preferences from the 33 blue models chose slightly differently depending on the kind of relationship they were thinking about and in any case showed they desired a size that turned out to be only slightly above the averages found across studies :. A number of different studies have sought to determine an average penis size. One published in took measurements of 3, young Italian men aged between 17 and 19 years.

It found the median average length of flaccid penises was 9 centimeters 3. Another study examined a different population, of physically normal Indian men, and sought to compare its results with size findings in other countries.

The results, the authors of the study said, "will help in counseling the patients worried about the penile size and seeking penis enlargement surgery. The findings, published in Nature, included a table that listed previous findings on penis dimensions around the world.

Click here to see the table. Of the 16 studies they cited, from various countries, the earliest was carried out over a hundred years ago and published in The authors of the study from India wrote that the definition of normal penile size was of "considerable interest" as there was a "steady increase in the number of people complaining of 'short penis' and seeking penile enlargement procedures.

Other research has suggested that most men who seek surgery to lengthen their penis have an overestimated view of what a normal penis size is. In the study of 67 men complaining of a short penis, none was, in fact, found to be severely short. The authors said there was an increasing number of men seeking surgery to lengthen their penis.

In , researchers in Saudi Arabia published the results of a retrospective cohort study of men with an average age of Men were excluded from the study if they were under 18 years old, presented with a complaint of small or short penis, Peyronie's disease , congenital curvature, clinical hypogonadism, previous penile surgery or trauma, or a combination of any of these. After medically inducing an erection the researchers took measurements and established an average:.

The researchers also measured the men's body-mass index BMI , which increases with obesity. There was a weak correlation between greater BMI and shorter erect penile length when this was measured from the skin over the pubic area, but not when the measurement was made from the bone to the tip. This suggests that the penis would appear to be shorter when there is more fat under the skin at the visible base of the penis.

However, the authors noted that slight decreases in size may be of limited concern to "aging men" - they found "the difference between men of 70 and 20 was less than a centimeter. Research findings on penis size from MNT news. A new finding shows evidence of a link between the relative length of a man's index and ring fingers and a way to predict the length of his penis. Want a longer penis?

Traction beats surgery, say researchers. Men who want surgery to increase the length of their penis should try non-invasive methods like penile traction devices or extenders first, and in some cases, even try therapy to make them feel more confident about their bodies, said Italian urologists in a paper published in the April issue of the British Journal of Urology International.

A lot of men worry about their penis size. But researchers hope the results of a new study, which reveals the average penis length, will reassure many men that they are 'normal. Read this article in Spanish. Table of contents When is penis size too small?

While 85 percent of women may be satisfied with the size and proportion of their partner's penis, men are less sure of themselves. As much as 45 percent of men believe they have a small penis. Across studies, flaccid length average from 7 to 10 centimeters 2.

Flaccid circumference or girth average ranges from 9 to 10 centimeters 3. Erect lengths average from 12 to 16 centimeters 4. Erect circumference is around 12 centimeters 4. The penis extends back behind the testes - measured lengths do not include this part.

Conceived and designed the experiments: NP GM. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference.

These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average. Both men and women often have reported discomfort with the appearance of their genitals. While not as common of a concern as body weight, muscularity, amount of head hair and body hair, or height, penis size was a concern for Concerns about genital appearance are unique compared to other concerns about physical appearance.

First, only intimate partners generally know the appearance of genitals. In contrast to the penis, body weight, acne, and other features are easily observed, informing feelings of attraction early in interactions. While indicators of penis size include ethnicity [ 2 ] and finger length and ratio [ 3 , 4 ], most proposed cues of penis size, including male height and foot size [ 5 ], weight [ 6 , 7 ], shoe size [ 8 ], and age [ 9 ], are unreliable.

Second, no diet, pill, or exercise regime affects the size or shape of genitals. However, about half of men in one study believed that they could change their penis size through non-surgical means [ 10 ]. Little can be done to change the appearance of the penis.

Contrary to some public opinion, it also is worth noting that discomfort with the appearance of the penis is not impacted [ 11 ], or is positively impacted [ 12 ], by viewing sex films. These anxieties may be unnecessary. Furthermore, most men seeking surgery to increase their penis size e. Of course, penis size need not affect sexual functions like orgasm, sexual drive, or pain experience.

However, men who are less satisfied with their penis report more sexual health problems [ 17 ]. A smaller penis decreases sexual confidence [ 18 ], which may be why penis size is related to sexual function. The context of the sexual relationship could influence penis size preferences.

For example, the goal of the sexual interaction with a one-night partner tends to be pleasure [ 20 ]. Women recognize that infection risks are higher from a one-night partner [ 21 ].

While women adjust their behaviors for this risk, being less likely to engage in anal sex [ 22 ] and more likely to use condoms [ 23 ] with one-night partners, such risky behaviors themselves are often experienced as pleasurable [ 24 ]. On the other hand, vaginal intercourse always causes tears in the vaginal mucosa [ 25 ] especially in the sensitive posterior fourchette [ 26 ], so women might prefer a smaller penis less likely to stress their physiology for regular, long-term mates.

Thus, women might shift their preferences for penis size depending on the type and duration of sexual relationship. Studies of penis size preference to date have relied on numerical size estimates, vague qualitative descriptions, or 2-D line drawings. For example, some studies have asked participants to specify penis length preferences in centimeters [ 27 ].

Another study asked participants to indicate their preference from reading erotic passages with three qualitative penis size options small, medium, large [ 28 ]. Yet, humans judge sizes most accurately when visual and haptic information are available together [ 29 ].

Both sources of data are usually available in sexual interactions. Thus, in this study, three-dimensional 3D models were used with the hope of increasing accuracy, ecological validity, and external validity. Also, most studies of penis size preference have portrayed or asked about the penis in its flaccid state [ 30 , 31 ].

It is unclear how well flaccid size reflects erect size. Of course, intercourse can occur only with a sufficiently rigid penis [ 36 ]. Thus, it seemed important to characterize preferences for penis size in its erect state. Three-dimensional 3D printing is just beginning to be used to assess shape perception and categorization. On the one hand, visual 2D information as compared to haptic information from 3D result in similar solutions for object similarity [ 37 ].

Each mode of information visual or haptic also improves categorization in the other domain [ 38 , 39 ]. Haptic information from 3D objects improved shape identification compared to raised lines alone [ 40 ] and improves later performance in the visual domain [ 41 ], possibly by improving discriminability [ 42 ].

Also, haptic information is robust to differences in perceptual acuity, such as occur with aging [ 43 ], which make such stimuli attractive when the visual acuity of participants may vary. This study extends the existing work using 3D stimuli to assess size preferences. Yet there are relatively few studies of erect penis size. This may reflect cultural taboos against researchers or doctors interacting with men who are in a sexually aroused state.

Two studies of erect penis sizes provided kits for home measurement [ 47 , 48 ]. Pharmacologically-induced, physician-measured erections identified an average length of Women prefer more masculine partners for shorter-term sexual relationships [ 20 ].

Women also value intelligence more, and attractiveness less, for long term, as compared to short term, partners [ 49 ]. Since a larger penis size is perceived as more masculine [ 53 , 54 ], we predict women will prefer a larger penis for shorter-term sexual relationships. Women likely make penis size judgments partly using their recalled experiences.

Yet, it is unclear how accurately women can recall penis size. Exposed to nude male images, women do attend to the genital area [ 55 , 56 ]. Based on previous studies see above about the distributions of penis length and circumference, the average American erect penis length was estimated as 6 inches This resulted in length ranging 4.

This yielded a 10 X 10 matrix of possible sizes. However, such a large choice set could overwhelm participants. Shading indicates the average penis length and girth in the USA. Units are in inches. The penis model shape was a cylinder, representing the shaft, topped by a dome, representing the penis head see Fig 2. Of course, the human penis shaft is comprised of three corpora that could be better represented by a rounded triangle and a more complex glans.

Also, no veins, testicles, or other details of the penis were portrayed. These details were not represented for three reasons. First, there are no mathematical descriptions available to accurately represent normal proportions of more complex penile structure. Second, women generally rate male nudes as less attractive than heterosexual men rate female nudes [ 57 ], so making the penis model more realistic might have provoked negative responses.

Third, the study was focused on overall penis size, not penis shape or surface details. While one motivation behind the current study was to improve the ecological validity of the stimuli, these concerns suggested starting with a more simplistic, erect penis model.

B Examples of 4 of 33 3D models showing length in inches. A and D represent the largest and smallest models in the set, respectively; B and C represent the two models counterbalanced used to test recall for size. Dimensions of commercial penile models do not vary systematically, so they were not appropriate for research purposes. Files were created using object-oriented Tinkercad [ 58 ] and compiled to. Models were light-weight, sturdy plastic with a smooth surface see Fig 1. After printing, models were checked by measuring tape to ensure accuracy of length and circumference.

None required reprinting for accuracy. The models were identified by randomly assigned letters e. Baskets were randomly shuffled between participants to reduce selection bias.

The flyers stated that women were requested to volunteer for a study concerning sexuality. The flyer did not mention penis size preferences. Women volunteered by either phone or an online form requesting a phone call. They completed a phone screening to confirm their eligibility e. Afterwards, they were given a chance to ask questions, then the experimenter asked whether they still wish to participate. If the participant verbally consented, the experimental protocol started.

The Informed Consent document stated that continuing at this stage constituted consent. Participants never provided their names. Next, the participant answered questionnaires described below presented on a computer in a private room, using a secure connection, on private laboratory server space scripted by the first author in php5. This took about 50 minutes and included the penis size preference tasks and questionnaires see below.

Computer presentation of questionnaires has been shown to increase the reporting of socially less desirable behaviors [ 60 ]. After the questionnaires, she completed a minute computer task data to be reported elsewhere assessing attention to sexual images. The self-report questionnaires included demographic information e.

These were used to characterize the sample. Other personality questionnaires were included, such as the Sexual Desire Inventory [ 61 ] and the Sociosexual Orientation Scale [ 62 ] to characterize the sample. After completing the other questionnaires, the experimenter entered with one of the two test models. Two of the original 33 models were randomly selected and reprinted indicated in black cells in Fig 2.

The experimenter informed the participant that she would be handed a model. She was instructed that she would be asked to try to recall the size of the model after inspecting it. During the inspection, she was asked not to measure the model using any objects in the room, but no instruction was provided regarding how she used her own hands. The participant recorded the letter code from the bottom of that model into the computer. The delayed-recall task was similar, except this time, the participant did not immediately search for the model.

Instead, she was given ten minutes to complete the penis size preference questionnaire below. After this, the participant was instructed to attempt to locate the second model from the 33 described above. The test models were counter-balanced, so the recall type immediate or delayed would not be confounded with test model size larger or smaller. After completing the immediate recall task, participants answered 15 questions about their penis size preferences.
