Penile length and circumference dimensions: A large study in young Italian men

Abstract

The aim of the present study was to evaluate the size of the penis in flaccidity and in erection of Italian men. A total of 4,685 men living in Italy and who have been visited at the Italian urology operating units were involved in the study between January 2019 and January 2020. Each patient was given details on how to measure their penis (erect length and circumference) in flaccidity and in erection, from the lower base to the distal penile tip. Mean (standard deviation [SD]) flaccid penis length was 9.47 (2.69), mean (SD) flaccid penis circumference was 9.59 (3.08), mean (SD) erect penis length was 16.78 (2.55) and mean (SD) erect penis circumference was 12.03 (3.82). At the linear regression analysis, height was associated with flaccid penis length (β = 0.04; p‐value = .01), and erect penis length was (β = 0.05; p‐value < .01) and erect penis circumference was (β = 0.06; p‐value < .01). Height is proportional to the length of the penis in flaccidity and in erection, and to the circumference in erection. The increase in BMI leads to a reduction in the length of the erect penis, as well as weight gain reduces the length of the flaccid penis.

Worldwide Temporal Trends in Penile Length: A Systematic Review and Meta-Analysis

“…The study characteristics of each article including patient description and dimensions recorded are summarized in Table 1 [ 3 12 13 14 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 ]. Of the seventy-five studies included, nineteen were conducted in North America [ 14 21 22 23 24 25 …”

“…The age ranged from 18 to 86 years with articles published between 1942 and 2021. Among the studies included, fourteen [ 21 32 34 37 38 39 40 44 53 60 62 69 79 81 ] and six [ 12 26 41 65 70 78 ] reported measurements obtained with penile injections and spontaneous erections, respectively.…”

“…Penile size has been measured in several studies but no comprehensive study exists to examine geographic variation or temporal trend [ 12 13 14 ]. The aim of this systematic review and meta-analysis is to critically evaluate the literature to report the trend of penile length over time and in different geographic regions.…”

“…We are aware, and it is one of the limitations we discussed in our article (Mauro et al, 2021), that there is inter-observer variability with regard to the measurements performed. Recall that to reduce the measurement error, each patient was given detailed and illustrated instructions on how to measure their penis (length and erect circumference) in flaccidity and erection and that all measurements were performed in similar environmental conditions (air-conditioned environment and temperatures ranging from 23 to 25℃).…”

“…Recent studies suggest that erectile function is to be considered a disease with multifactorial pathogenesis, in fact it appears to be associated with multiple risk factors including age, obesity, smoking, alcohol, diabetes, cardiovascular disease or psychological variables (Gul et al., 2021 ; Mauro et al., 2021 ; Wan et al., 2021 ).…”
