Should You Be Worried About Dark Spots On Your Penis?

Sudden dark spots on your penis freaking you out? They’re no cause for worry. Like any other part of your body, your genitals are also prone to skin changes and dark spots are part of them. Most dark spots – which appear in different sizes, shapes, and shades – are usually harmless unless they change in the way they look over time. Let’s look at the various reasons black spots may appear on your penis and how you can treat them at home.

Causes Of Dark Spots On The Penis

1. Penile Melanosis

The most common cause of dark spots on the penis is penile melanosis. This condition is characterized by a brown to black colored flat patch usually seen on the shaft of the penis. Such a patch is usually harmless and does not require treatment.1 The pigmented area may look irregular and can be confused with a penile tumor. However, a penile tumor is not as common as you think and is said to represent only one percent of the total occurrences of this condition. Your doctor may suggest a biopsy to rule out a tumor if there is any severe abnormality in the discolored region.


2. Post-Inflammatory Hyperpigmentation

You can contract allergic dermatitis (a contact allergy due to an irritant) on the skin of your
penis if you are allergic to something you use around your penis like soap or shampoo. This condition inflames the skin in the affected area and causes hyperpigmentation – harmless skin darkening caused by excess production of the pigment melanin – which usually does not require treatment and fades with time. Hyperpigmentation can also be an inherited genetic condition or can occur due to metabolic disorders or even certain medications.2

3. Pigmented Warts

Sexual contact with an infected partner can lead to pigmented warts on the penis. These warts, caused by the human papillomavirus (HPV), are transmitted through sexual intercourse.3 They are often painless and start out as small pink or red protrusions and then spread rapidly to form clustered protrusions on the skin of the penis. While they may disappear if left untreated, warts are usually contagious so it’s best to get them treated. However, they can recur after treatment. So, always get yourself checked if you notice rapid growth of warts on your penis to rule out any malignancy. Remember to keep your sexual partner informed of your condition.


4. Pigmented Nevus (Moles) Of The Penis

Moles can appear on the penis quite frequently. They form on penile skin folds and are pale brown or black. They are usually harmless and do not require any treatment. However, any genital mole that enlarges or changes in color over time could be a cause for concern.

Home Remedies For Penile Dark Spots

If you’ve identified with any of these issues and want to do something about it, here are a few simple and effective home remedies you can try. Remember to do a patch test before applying any of these to the affected area to avoid allergic reactions.
