Circumcision

Circumcision refers to the removal of the foreskin from the penis. It may be done for many reasons, primarily religious and cosmetic, as well as medical.

Circumcision's impact on sexual health, pleasure, and function has been studied extensively, though often using limited metrics. Broad functional surveys of thousands of men report no significant differences in the basic mechanical ability to achieve arousal, erection, or orgasm. But other research has focused on the anatomical and sensory changes associated with removing the foreskin, which contains specialized mucocutaneous tissue rich in fine-touch nerve endings. Studies have found that its removal may cause difficulty in achieving orgasm and impact sexual satisfaction and function.

Circumcisions may be described as high or low, tight or loose. High and low describe the placement of the scar on the shaft, whereas tight and loose refer to how much foreskin has been left.

Circumcision and Sexual Health

Circumcision has been associated with certain health benefits, including a marginally reduced risk of infant urinary tract infections, rare penile cancers, and some sexually transmitted infections, such as HIV. Adult clinical trials conducted in Sub-Saharan Africa found that Voluntary Medical Male Circumcision (VMMC) significantly reduced the risk of HIV in heterosexual men, providing 50–60% relative protection in those specific, high-prevalence epidemics.

However, peer-reviewed literature has criticized the methodology and conclusions of these trials, citing issues such as lead-time bias and early termination. These criticisms, along with major differences in HIV prevalence and access to preventative measures, have also raised questions about how applicable the findings are to routine infant circumcision in other populations. The Canadian Paediatric Society does not recommend the routine circumcision of every newborn boy, while the Royal Dutch Medical Association (KNMG) takes a stronger position, stating that “there is no convincing evidence that circumcision is useful or necessary in terms of prevention or hygiene.”

Circumcision and Medical Conditions

While circumcision is sometimes recommended to treat specific penile conditions, it is rarely the only option. The most common conditions include:

• Phimosis: A condition where the foreskin is too tight to be retracted (pulled back) over the head of the penis (glans). While this is completely normal in infants and young boys, if it persists into adulthood and causes pain (pathologic phimosis), it may require treatment. First-line treatment is usually non-surgical, involving topical steroid creams and gentle stretching exercises.
• Paraphimosis: This occurs when the foreskin is pulled back behind the head of the penis and becomes stuck, causing swelling that prevents it from returning to its normal position. This is often the result of forcibly retracting the tight foreskin.
• Balanitis: An inflammation (or infection) of the head of the penis and the foreskin. It is most commonly resolved with proper hygiene, antifungal, or antibacterial creams. Balanitis may also be the result of an underlying skin condition.

When conservative treatments like steroid creams do not resolve the issue, several less-invasive surgeries maintain the structure of the foreskin without removing it entirely. Some such surgeries include v-plasty, z-plasty, frenuloplasty, and preputioplasty . It is recommended to seek a second opinion from a specialised urologist to discuss available conservative and reconstructive alternatives before committing to a full circumcision.
