We aimed to develop percentiles and means (and standard deviations) of stretched penile length (SPL) in Japanese boys. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; A cross-sectional study was performed in 1,628 Japanese boys aged &lt;9 years from 2007 through 2014. The LMS method was used to develop a growth reference and chart for SPL in boys aged 0-7 years. Interobserver variation in SPLs was assessed in 32 boys (aged 0-11 years, median 3 years) using the Bland-Altman plot. The correlation between SPL and stature, weight or body mass index (BMI) was analyzed by the Pearson test. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; SPL increases continuously during the prepubertal period, and most rapidly in the first 4 months of life. No significant fixed or proportional bias was found for interobserver variation (p = 0.5; r&lt;i&gt; = &lt;\/i&gt;0.33, p = 0.06). There was no significant correlation between SPL z-score and stature z-score (r&lt;i&gt; = &lt;\/i&gt;0.14, p &lt; 0.001), weight z-score (r&lt;i&gt; = &lt;\/i&gt;0.09, p &lt; 0.001) or BMI z-score (r = 0.01, p = 0.71). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; These data serve as an updated growth reference for SPL in Japanese boys aged 0-7 years.<\/jats:p>","DOI":"10.1159\/000368965","type":"journal-article","created":{"date-parts":[[2014,12,3]],"date-time":"2014-12-03T07:21:22Z","timestamp":1417591282000},"page":"388-393","source":"Crossref","is-referenced-by-count":21,"title":["A Cross-Sectional Growth Reference and Chart of Stretched Penile Length for Japanese Boys Aged 0-7 Years"],"prefix":"10.1159","volume":"82","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7360-2465","authenticated-orcid":false,"given":"Tomohiro","family":"Ishii","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobutake","family":"Matsuo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikako","family":"Inokuchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomonobu","family":"Hasegawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2014,12,3]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.4780111005"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3109\/03014460.2012.694475"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1080\/03014460600802353"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1159\/000050013"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(86)90837-8"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/uog.122"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1001\/archpediatrics.2010.223"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2007.04.051"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1515\/JPEM.2000.13.1.55"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1530\/eje.1.02066"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/PL00008350"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ijo.0801436"}],"container-title":["Hormone Research in Paediatrics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/368965","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/368965","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:56:52Z","timestamp":1745431012000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000368965"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":12,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2015,1,1]]},"published-print":{"date-parts":[[2015,1,19]]}},"URL":"https:\/\/doi.org\/10.1159\/000368965","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.5127241","asserted-by":"subject"}]},"ISSN":["1663-2818","1663-2826"],"issn-type":[{"value":"1663-2818","type":"print"},{"value":"1663-2826","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014]]}}}
