Why does the glans turn black after circumcision?

Blackening of the glans after circumcision is usually caused by subcutaneous congestion, poor blood circulation, inflammation and infection.

Circumcision surgery usually causes local irritation, which may lead to local blood vessel rupture, local congestion, and local blackening of the skin.

Surgery may also cause local poor blood circulation, which will affect blood circulation. This is generally a normal postoperative symptom and can usually be improved and recovered on its own.

If the local area is infected by bacteria or viruses, it will usually lead to local blackening, pain and swelling. You need to take amoxicillin capsules, cefixime tablets, etc. as directed by your doctor.
