The natural foreskin is composed of smooth dartos muscle tissue (called the peripenic muscle [16]), large blood vessels, extensive innervation, outer skin, and inner mucosa. [17] The process of foreskin restoration seeks to regenerate some of the tissue removed by circumcision, as well as provide coverage of the glans.
This condition prevents the full retraction of the foreskin with or without an erection. [1] It is a simple and normally painless procedure that is performed in a urologist's office. First the physician applies a local anesthetic, such as lidocaine/prilocaine cream on the frenulum and surrounding area. If the patient retains any feeling there ...
The function of a foreskin retainer is to keep the glans penis covered by the available foreskin. A foreskin retainer can be used when newly grown foreskin is neither long enough nor tight enough to keep the glans covered itself, but is long enough that it can be stretched past the glans (which is necessary to facilitate the use of a retainer).
Circumcised at birth, the foreskin has been restored over years of foreskin restoration. Foreskin restoration is the partial recreation of the foreskin after its removal by circumcision . Surgical restoration involves grafting skin taken from the scrotum onto a portion of the penile shaft.
This may be a complication of circumcision or a naturally occurring event. When it is a naturally occurring event, a short frenulum can restrict normal retraction of the foreskin during erection (a condition known as frenulum breve). The goal of treatment is to allow normal retraction of the foreskin.
The enlarged and bulbous-shaped end of the corpus spongiosum forms the glans penis with two specific types of sinusoids, which supports the foreskin, a loose fold of skin that in adults can retract to expose the glans. [9] The area on the underside of the glans, where the foreskin is attached, is called the frenulum.
There are three mechanical conditions that prevent foreskin retraction: The tip of the foreskin is too narrow to pass over the glans penis. This is normal in children and adolescents. [26] [27] The inner surface of the foreskin is fused with the glans penis. This is normal in children and adolescents but abnormal in adults. [27]
At birth, the foreskin cannot be retracted due to adhesions between the foreskin and glans, and this is considered normal (physiological phimosis). [59] Over time the foreskin naturally separates from the glans, and a majority of boys are able to retract the foreskin by age three. [59] Less than one percent are still having problems at age 18.
