Correctly performed circumcisions are least likely to require revisions.

All conventional newborn circumcision techniques can be done safely with the correct training and experience. No technique is superior for all children under all circumstances. The most common techniques include Plastibell, Gomco, and Mogen Clamp. These techniques all involve removing the foreskin that covers the glans (head) of the penis. Each has pros and cons and, if done correctly, should provide acceptable outcomes.

The goal always is to remove just the foreskin and NOT the normal skin covering the penile shaft. If the shaft skin is removed it can cause a ‘tight’ penis or, in extreme cases, a penis with no shaft skin. If too little is removed then the remaining foreskin still will partially cover the penis and require more care and hygiene in the future.

Care providers should always err on the side of too little foreskin removed than too much removed. With good training and experience, most newborn and infant circumcisions can be done with the correct amount of foreskin removed. See Outcomes for more information.

Like the body, newborn penises come in many shapes and sizes. Fortunately, even with their differences, penises are most commonly ‘normal.’ However, when skin coverage is slightly different, it may require special consideration be given to when, who, and how the circumcision is performed.

In some cases, circumcision should be deferred until a specialist, like a pediatric urologist, can assess to determine if it can be safely done as an infant with the conventional methods or if it should be performed later as a surgical procedure.

Common Penis Abnormalities

The following infant penis shapes may require special circumcision considerations or be performed by a pediatric urologist. (Hover over the images to identify each type.)

#1 Normal Penis: The first image above is of a normal, uncircumcised penis.

#2 Webbed Penis: This mild deformity is more of a “tepee” shape (while the normal uncircumcised penis is more of a “rocket” shape). In this case, a circumcision, if not done very carefully, may result in too much external shaft skin being removed. This may require a surgical circumcision in the operating room, not circumcision by a clamp or plastic ring device. Also, regardless of the technique used, it will probably require the parents to ‘pop out’ the glans (head) often to make sure the shaft skin relaxes and allows easy exposure for future care and exposure.

#3 Concealed/Hidden Penis: This is a significant penile abnormality that should be addressed by a specialist (pediatric urologist) especially if circumcision is desired. An excellent outcome should be expected. The penis is normal, just the external skin is deficient. This also will probably require a formal circumcision in the operating room, and for the parents to regularly ‘pop out’ the penis until all the shaft skin relaxes.

#4 Mild Chordee: This deformity is usually caused by deficient foreskin development under the penis. Instead of having equal foreskin all around the penis, this chordee deformity has all the foreskin on the back side of the penis near the abdomen. Many of these children will have some curvature of the penis, especially with erection. This deformity is also usually mild and easily corrected in the operating room by a pediatric urologist and an excellent outcome is usually obtained. If uncorrected, the penis will have an odd shape since it will never have a normal, uncircumcised appearance and may have curvature.

#5 Naturally Circumcised: Natural circumcision is a term used when a baby is born with less foreskin and appears slightly circumcised. This term is commonly used but not accurate in that foreskin is still present. In this case, the glans and meatus are visible but there is still circumferential and relatively normal foreskin present. Children with a “natural circumcision” can still be circumcised if desired by the parents and an experienced care provider can usually perform this as a newborn procedure—but with care not to remove too much foreskin.

#6 Hypospadias: Newborns and infants with significant bleeding, skin, or other disorders should only undergo circumcision with the correct medical preparation.


Many avoidable complications and suboptimal outcomes arise when boys with mild penile deformities are subjected to a routine newborn circumcision by a practitioner who does not have extensive experience with unusual or different penile anatomy.
