The practice of circumcision represents one of the oldest and most frequently performed surgical procedures in the history of medicine, bridging the divide between cultural tradition, religious observance, and evidence-based clinical practice. Within the context of modern urology at Liv Hospital, circumcision is defined as the surgical removal of the prepuce, commonly referred to as the foreskin, which is the retractable fold of skin and mucous membrane covering the glans penis. While the procedure is conceptually straightforward, the anatomical and physiological implications are profound, involving the permanent alteration of the penile integument and the exposure of the glans to the external environment. The procedure transforms the male genitalia from a state where the glans is protected by a mucosal hood to one where the keratinized epithelium is permanently exposed. This transition has significant implications for hygiene, disease prevention, and urological health.
The prepuce is not merely a superfluous layer of skin; it is a complex anatomical structure composed of an outer keratinized layer, a muscular dartos fascia, and an inner mucosal layer that is rich in specialized nerve endings, including Meissner’s corpuscles. In the uncircumcised state, the inner prepuce creates a moist, warm environment against the glans, known as the preputial sac. This environment, while physiological, can predispose individuals to specific dermatological and infectious conditions if homeostasis is disrupted. The surgical definition of circumcision involves the precise excision of this tissue, ensuring that the remaining shaft skin is approximated to the mucosal collar just proximal to the corona of the glans. The goal is to achieve a cosmetic and functional result where the glans is fully exposed, eliminating the preputial space entirely.
Following the excision of the prepuce, the penis undergoes a process of adaptation. The most immediate change is the loss of the preputial mechanism that allows the skin to glide over the glans. In the uncircumcised male, this gliding mechanism facilitates intercourse and masturbation by reducing friction. Post-circumcision, the mechanics of sexual function are altered but not diminished; the shaft skin remains mobile, but the glans itself becomes the primary point of contact.
Over time, a process known as keratinization occurs. The mucosal surface of the glans, which was previously protected and moist, thickens slightly and becomes drier in response to constant friction with clothing. This keratinization serves as a protective barrier against abrasion and microbial invasion. It is a common subject of debate whether this thickening reduces penile sensitivity. However, extensive clinical studies generally suggest that while the character of sensation may change due to the removal of the fine touch receptors in the foreskin, overall sexual satisfaction and ejaculatory latency time remain largely unaffected or, in some cases of premature ejaculation, may even improve due to slightly reduced hypersensitivity.
At Liv Hospital, circumcision is approached with the same rigor and sterilization protocols as major urological surgery. It is not merely a cosmetic procedure but a surgical intervention that requires precise knowledge of penile vascularity and neuroanatomy. The procedure must account for the frenulum, a highly vascularized strip of tissue on the ventral aspect of the glans. Improper handling of the frenulum can lead to excessive bleeding or future tethering of the penis (chordee). Therefore, the definition of a comprehensive circumcision includes a frenuloplasty or frenulectomy when indicated, to ensure a symmetrical and tension-free result.
The procedure can be performed under local, regional, or general anesthesia, depending on the age of the patient and the specific clinical indication. In neonates and infants, the procedure is often quicker due to the thinness of the tissues, whereas in adults, the robust vascularity and thickness of the dermis require more extensive dissection and hemostasis. The surgical technique must be tailored to the individual anatomy, ensuring that the amount of skin removed is sufficient to prevent phimosis recurrence but conservative enough to prevent penile shortening or painful erections during arousal.
Circumcision is one of the most common surgical procedures performed globally, with an estimated 37 to 39 percent of males worldwide being circumcised. This prevalence varies drastically by geography, culture, and religion. In the medical context, however, the focus remains on the biological outcomes. The elimination of the moist sub-preputial environment removes the breeding ground for anaerobic bacteria and smegma—a combination of exfoliated skin cells and oils. While smegma itself is not pathologic, its accumulation can lead to irritation and inflammation. By removing the anatomical structure that harbors these fluids, circumcision simplifies genital hygiene, requiring only standard washing rather than retraction and cleaning of the preputial sac.
In summary, the overview of circumcision describes a procedure that is technically standardized yet biologically impactful. It represents a permanent modification of the male anatomy that confers specific hygienic and prophylactic advantages, shifting the physiological state of the penis from a mucosal-covered organ to a keratinized, exposed one.

The primary difference lies in the presence of the prepuce or foreskin. In an uncircumcised penis, the glans (head) is covered by a double-layered fold of skin and mucous membrane that retracts during erection or cleaning. In a circumcised penis, this tissue is surgically removed, leaving the glans permanently exposed and connecting the shaft skin directly to the mucosal collar behind the glans.
No, while it has deep roots in religious and cultural traditions, circumcision is also a widely practiced medical procedure. It is performed therapeutically to treat conditions like severe phimosis or chronic inflammation, and prophylactically to reduce the risk of urinary tract infections in infants and sexually transmitted infections, including HIV and HPV, in adults.
Circumcision does not change the physical size of the penis in terms of the erectile bodies (corpora cavernosa). However, removing the foreskin can create an optical illusion where the penis appears slightly larger or more defined because the glans is no longer hidden. Conversely, if too much skin is removed, it can feel tight during erection, but the actual anatomical length remains unchanged.
Keratinization is a physiological process where the skin of the glans thickens slightly and becomes drier after circumcision. In an uncircumcised male, the glans is a mucous membrane similar to the inside of the cheek. After circumcision, constant contact with clothing causes the outer layer of cells to produce more keratin, making the surface tougher and more resistant to abrasion.
Yes, the technique and complexity vary significantly. Infant circumcision is often performed using clamp devices (like Gomco or Plastibell) due to the thinness of the tissue and rapid healing. Adult circumcision is a more formal surgical dissection involving scalpel excision, cauterization of blood vessels, and suturing, as the adult foreskin is vascular, thicker, and fully developed.
