Results
Skin and mucosa sufficient to cover the penile shaft was frequently missing from the circumcised penis. Missing tissue included a band of ridged mucosa located at the junction of true penile skin with smooth preputial mucosa. This ridged band contains more Meissner's corpuscles than does the smooth mucosa and exhibits features of specialized sensory mucosa.
Conclusion
The amount of tissue loss estimated in the present study is more than most parents envisage from pre-operative counselling. Circumcision also ablates junctional mucosa that appears to be an important component of the overall sensory mechanism of the human penis.

Circumcision performed in the newborn period traumatically interrupts the natural separation of the foreskin from the glans that normally occurs somewhere between birth and age 18. The raw, exposed glans penis heals in a process that measurably thickens the surface of the glans and results in desensitization of the head of the penis.
When circumcision is performed after the normal separation of the foreskin from the glans, the damage done by forcible separation of these two parts of the penis is avoided, but the glans must still thicken in order to protect itself from constant chafing and abrasion by clothing.
The thickened, drier tissue covering the glans of the circumcised penis may necessitate the use of synthetic lubricants to facilitate nontraumatic sexual intercourse. Often, it is erroneously considered the woman's lack of lubrication that makes intercourse painful rather than the lack of natural male lubrication, which is more likely the cause. During masturbation, the circumcised male must use his hands for direct stimulation of the glans, and this may require synthetic lubrication as well.
In addition to the predictable physical changes that occur with circumcision, there are inherent risks and potential complications from the surgery. These include, but are not limited to, hemorrhage, infection, surgical damage and, while rare, death. Surgical damage and healing complications can result in extensive scarring, skin bridging, curvature of the penis, and deformities of the glans penis and urethral meatus (urinary opening). Extreme mutilations have resulted from inappropriate electrocautery use in circumcision, causing loss of the entire penis. Sex-change operations have been used as a ``remedy'' for this iatrogenic condition.

Conclusions Circumcision was associated with frequent orgasm difficulties in Danish men and with a range of frequent sexual difficulties in women, notably orgasm difficulties, dyspareunia and a sense of incomplete sexual needs fulfilment. Thorough examination of these matters in areas where male circumcision is more common is warranted.
