Dark Spots on Genitals: Causes and When to Seek Help

Dark spots in the genital area?

A month ago, while taking a shower, I suddenly noticed that my testicles and penis had developed some spots resembling black moles.
Some of them are slowly getting larger.
Other areas, like small black moles that I had since childhood, are also gradually expanding.
Could this be a sexually transmitted infection? I'm feeling a bit anxious and don't know what to do.
If I need to see a doctor, should I go to a dermatologist or a urologist?

More Info

When it comes to dark spots on the genitals, it is essential to approach the situation with caution and awareness. The appearance of new spots, especially those that resemble moles or dark lesions, can be concerning, and it’s understandable that you feel anxious about it. There are several potential causes for these dark spots, and understanding them can help you determine the next steps.

Firstly, it’s important to note that not all dark spots on the genitals are indicative of a sexually transmitted infection (STI). Some common benign causes include:
1. Seborrheic Keratosis: These are non-cancerous growths that can appear anywhere on the body, including the genital area. They often appear as brown or black spots and can vary in size.

2. Moles (Nevi): If you have had moles in other areas of your body, it’s possible that new moles can develop in the genital region. Moles can change in size and color over time.

3. Hyperpigmentation: This can occur due to friction, hormonal changes, or other factors, leading to darkened areas of skin.

4. Skin Tags: These are small, benign growths that can appear in various areas, including the genital region.

5. Infections: Certain infections, including some STIs, can cause changes in the skin, including the appearance of spots or lesions. For example, herpes can cause sores, while warts caused by the human papillomavirus (HPV) can appear as raised bumps.

Given that you mentioned some spots are expanding, it is crucial to seek medical advice. Changes in the size, shape, or color of any skin lesion can be a sign that it needs further evaluation.

When to Seek Help
You should seek medical attention if:
- The spots are changing in size, shape, or color.

- You experience any discomfort, itching, or pain in the area.

- There are additional symptoms such as discharge, bleeding, or swelling.

- You have any concerns about STIs or other infections.

Which Specialist to See
In terms of which specialist to consult, both dermatologists and urologists can address your concerns. A dermatologist specializes in skin conditions and can evaluate the spots on your genitals, while a urologist focuses on the urinary tract and male reproductive system. If you are unsure, starting with a dermatologist may be a good option, as they can assess the skin lesions and refer you to a urologist if necessary.

Conclusion
In summary, while dark spots on the genitals can be benign, it is essential to monitor any changes and seek medical advice to rule out any serious conditions. Early evaluation and diagnosis can lead to appropriate treatment if needed and provide peace of mind. Remember, it’s always better to err on the side of caution when it comes to your health. Don’t hesitate to make an appointment with a healthcare provider to discuss your symptoms and concerns.
