What is the cause of black mole on penis

Black moles on the penis may be caused by long-term friction, inflammatory stimulation or pigmentation.

1. Long-term friction: If it is black, without any bumps and smooth, or even without any symptoms, generally no special treatment is required. This is a common problem, which is mainly caused by long-term friction and is a physiological phenomenon of the skin. However, you need to pay attention to local hygiene care, wear cotton underwear, and reduce local friction.

2. Inflammatory stimulation: If you do not pay attention to local hygiene care for a long time, inflammatory infection is likely to occur, and inflammatory stimulation can also induce pigmented nevus. It can usually be improved by laser method, mainly by directly acting on the pigmented nevus through pulsed strong light, which can make the melanin particles under the skin explode and decompose as soon as possible, and then be excreted through the body's metabolism.

3. Pigmentation: If there is an obvious increase in melanin particles in the local area, it is likely to induce a melanocytic nevus, which generally does not cause pain or discomfort. Laser or freezing treatments can also be used to improve the appearance of the skin.

It is best to go to the andrology department of a local regular hospital for relevant examinations, and then make targeted adjustments based on your own situation. In addition, you need to pay attention to avoid excessive psychological pressure or excessive tension.
