The age at which the circumcision had been done was\u00a0assessed. The patients\u2019 height and weight were measured. Second\u00a0to fourth digit ratio was calculated by measuring the second and\u00a0fourth digit lengths. The flaccid and erectile penile lengths were\u00a0measured from the base of the penis to the tip of the glans in\u00a0standing position.&lt;\/p&gt;&lt;p&gt;&lt;strong&gt;Results:&lt;\/strong&gt; A total of 248 patients were included in our study. In univariate\u00a0analysis, height, second to fourth digit ratio, flaccid penile\u00a0length, and age of circumcision were associated with erectile penile&lt;br \/&gt;length. Among these variables, second to fourth digit ratio, flaccid\u00a0penile length, and age of \u00a0circumcision were significant predictive\u00a0factors for erectile penile length in multivariate analysis. The subjects\u00a0were divided into two groups, including 72 patients in the\u00a0NMC group and 176 patients in the non-NMC group. No significant\u00a0difference was found in height, weight, and second to fourth\u00a0digit ratio between both groups. However, flaccid (p&amp;lt;0.001) and\u00a0erectile (p=0.001) penile lengths were shorter in the NMC group\u00a0than in the non-NMC group.&lt;\/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions:&lt;\/strong&gt; Despite the small number of subjects, this study\u00a0shows that NMC was associated with shorter penile length. Second\u00a0to fourth digit ratio, flaccid penile length, and age of circumcision\u00a0were also significant predictive factors for erectile penile length.\u00a0Further multicentre studies with larger number of subjects and\u00a0biochemical analyses are needed for potential clinical applicability&lt;\/p&gt;<\/jats:p>","DOI":"10.5489\/cuaj.3590","type":"journal-article","created":{"date-parts":[[2016,9,13]],"date-time":"2016-09-13T14:20:09Z","timestamp":1473776409000},"page":"296","source":"Crossref","is-referenced-by-count":11,"title":["Prospective investigation of penile length with newborn male circumcision and second to fourth digit ratio"],"prefix":"10.5489","volume":"10","author":[{"given":"Jong Kwan","family":"Park","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
