In most cases bleeding is minor and not fatal, but some babies can hemorrhage from this procedure.
A common issue with bleeding is it also can result in seizures and organ failure if extensive enough.
An Infant dies every other day in the US during circumcision, that we know of. Due to laws allowing doctors to code these deaths as heart failure, SIDS, or other options, it is possible that there are many more deaths that we are unaware of.
Quoted from Stanford Medical: “The most devestating reports of bleeding (leading to blood transfusion or death) during or after circumcision occur in boys who have underlying blood dyscrasias, so it is critical to inquire specifically about a family history of bleeding disorders before considering the procedure.”
Cysts that occur along the incision line, can lead to infection.
Death of tissue of the penis can be caused by numerous issues.
To name a few: improper cauterization or suturing, or improper placement of a circumcision device.
Formation of large masses of keloid Tissue on the incision have been reported.
Can be difficult to correct due to the fact that scarring causes keloids, and more surgical procedure will lead to more scarring.
Keloids are more easily obtained in people of color.
Due to the fact that an infants penis is so small and hard to correctly operate on, there are many cases of medical staff unintentionally slicing off the tip of the glans (penis head).
This is not easily fixed, and can lead to issues with ejaculation, urination, and a healthy future sex life
Very common circumcision complication.
Skin bridges are areas of skin that extend from the circumcision edge back onto the glans. They are thought to arise from areas of minor injury on the edge of the glans that become abnormally adhered to the circumcision edge. Because the area under the bridge is unattached, debris can collect underneath and create a problem with hygiene. Excision may be required.
