* The [[frenulum]] is too short to permit retraction. The medical name for this condition is ''[[frenulum breve]]''.
* The inner surface of the foreskin is fused or adherent by a [[synechia]] to the glans penis.

Physiological phimosis can be divided into three main categories - symptom-free, in need of therapy, and in need of surgery.
From a medical standpoint, an otherwise symptom-free [[phimosis]], even after dissolution of preputial adhesions, does not require any treatment before the child enters puberty. The widespread notion that full retractability has to be achieved by a certain age, derives from obsolete assumptions and studies which only covered children's development until they entered school, but not beyond that point.
Even though the data from Jakob Øster's studies (see above) have been known for 51 years, <ref name="Øster1968">{{REFjournal |last= |first=Jakob |title=Further fate of the foreskin: 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 |accessdate=2019-11-01}}</ref> some check lists for school doctors‘ examinations still erroneously refer to physiological phimosis as an abnormality.
In most cases only watchful waiting is necessary, not surgery or other treatment.

Teen boys with a non-retractable foreskin may benefit by manual stretching.
