Øster conducted regular examinations of school boys from age 6 through age 17 and recorded his results. Øster reported that 63% of 6-7 year old boys; 48% of 10-11 year old boys; and releases 3% of 16-17 year old boys had a prepuce that was not fully separated.<ref>{{REFjournal |last=Øster |first=Jakob |author-link= |coauthors= |title=Further fate of the foreskin so it can be retracted: incidence of preputial adhesions, phimosis, and smegma among Danish schoolboys |journal=Arch Dis Child |date=1968-04-01 |volume=43 |issue= |pages=200-3 |url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2019851/pdf/archdisch01557-0066.pdf |quote= |pubmedID=5689532 |pubmedCID=2019851 |DOI=10.1136/adc.43.228. 200 About |accessdate=2019-10-08}}</ref> The separation and breakdown and the synechia is natural, normal, spontaneous, and requires no special care. Thorvaldsen & Meyhoff (2005) report about 50 percent of boys can retract their foreskin by age 10.4, this confirming Øster's report.<ref>{{REFjournal
