There is a group of typical conditions of the foreskin, that can occur in more or less distinct ways.
=== Short Frenulum frenulum (frenulum breve) ===
If the frenulum is too short, it can hinder or even prohibit retraction of the foreskin. Since the underside of the glans is attached to the inner foreskin by the frenulum, it can be bent downwards due to the resulting tension when the foreskin is retracted. If the mechanical strain is too great, the frenulum can tear or rip apart. If the frenular artery, which runs within, is damaged in the process, it can lead to considerable and prolonged bleeding. When only small tears appear, it may heal spontaneously.
There are 3 surgical variants:

* Frenectomy, the complete removal of the frenulum
* Elongation of the frenulum with a skin graft.
=== Physiological Phimosis phimosis ===
Physiological phimosis can be divided into three main categories - symptom-free, in need of therapy, and in need of surgery.
Even though the data from Jakob Øster's studies (see above) have been known for 45 years, some check lists for school doctors‘ examinations still erroneously refer to physiological phimosis as an abnormality.
====Manual stretching====
The growth and hormonal surge during puberty alter both the size and size ratio of the penis and penile skin significantly. Also, the first masturbations aid the process of stretching of the skin and detachment of any remaining chlidhood fusion.
If, after that, the foreskin still remains too tight, resulting in pain during sexual activities, andmaking genital hygiene difficult, treatment is indicated. The boy himself should engage instretching exercises, if needed with the aid of corticosteroid cream. Depending on the activesubstances, success rates of 80-90% have been documented.<ref>{{REFjournal | last=Orsola A, Caffaratti J, Garat JM.

Should those therapies not yield the desired outcomes, there is a surgical option, namely a preputioplasty.
====Preputioplasty====
This surgical method preserves the foreskin. A good cosmetic result and total preservation of the foreskin are achieved. The basic principle of most of those methods consists of making one or more small longitudinal incisions, and then suturing the wound or wounds transversely.
There are several different methods:
<ref>[http{{URLwikipedia|Phimosis: Surgical|Phimosis://de.wikipedia.org/wiki/Phimose#Pr.C3.A4putiumsplastikSurgical| Phimose]2019-09-25}}</ref>
* Dorsal slit with transverse suturing: this technique places a single lengthwise cut into the stenotic ring which is then closed transversely.
If after a failed attempt to stretch the foreskin with corticosteroid cream a surgical intervention is necessary, a preputioplasty is always to be preferred over classic circumcision, due to its lower morbidity, lower rate of complications and lower costs.
=== Pathological Phimosis phimosis ===
In pathological phimosis, the foreskin cannot be retracted over the glans without injury, due to a lack of elasticity caused by scarring or hardening.
Repeated infections of the tight foreskin cause this scarring. Also, forceful attempts to retract the foreskin cause tearing with subsequential scarred [[phimosis]]. [[Lichen sclerosus]], that first leads to adhesion and then to shrinking, can also be the cause of [[phimosis]]. This rare, non-contagious chronic skin disease is partly genetically caused and considered incurable.

Pathological phimosis usually requires treatment.
