Circumcision surgical procedure in males involves either a conventional "cut and stitch" surgical procedure or use of a circumcision instrument or device. In the newborn period less than 2 months of age , almost all circumcisions are done by generalist physicians using one of three surgical instruments. Complications may also include bleeding , infection , reduction in sensation of the glans penis ,  and too little or too much tissue removal. Currently, most circumcisions in boys and men are performed using one of three open surgical methods. The forceps-guided method, the dorsal slit method, and the sleeve resection method are well described by the World Health Organization in their Manual for Male Circumcision under Local Anaesthesia.

However, new research is suggesting that getting a circumcision as an adult can provide some stunning health benefits for men. A lot of parents have their babies experience a circumcision when they are only a few days old, but men of all ages can have the surgery done — the most common age range for adults is between the ages of 20 and 40 years old. This loose flap of skin, called foreskin, is something that every male is born with, as it covers and protects the rounded, top portion of the penis. Foreskin contains blood vessels, nerves and a small amount of muscle. For those males who were not circumcised at birth, the foreskin that was once stuck to the penis eventually separates as they grow older.
Circumcision can be a simple and safe procedure to remove the foreskin from the penis. Though circumcision is typically associated with infants, boys, teens and men routinely receive the procedure. For many, circumcision is a decision related to faith or culture. New parents often follow family tradition and have their newborn sons circumcised. As boys reach adolescence, circumcision can sometimes be a solution to health issues such as phimosis.
