Penile Skin Rashes

The most common cause for itch and rash over the penis is fungal infection of the penile skin. Other possible causes include STDs like trichosomonas, which is a parasite. Redness or itchiness that do not heal must be assessed more seriously to rule out skin cancers of the penis.

Types Of Penile Skin Rashes

The swelling and irritation of the glans (head) of the penis is known as balanitis. In men who are not circumcised, this area is covered by a flap of skin, which we call the foreskin.

Fungal Balanitis

The most common cause of penile skin rashes is a yeast infection, known as fungal balanitis. During sexual intercourse, you may be exposed to fungus that can then trigger an infection of the penis.

Symptoms include:

• itching and redness on the penis
• thick white substance collecting in skin folds
• shiny, white skin
• painful penis and foreskin
• burning sensation while urinating
• discomfort during sex
• disagreeable smell

Inflammation Balanitis

If your condition is persistent, recurrent and causes semi-permanent changes to your penis, there is a chance the rash is more than a simple infection. It could be an inflammatory skin condition such as Lichen Sclerosus.

Symptoms include:

• painful, tight foreskin
• skin discolouration
• small tears

Fungal Balanitis Can Be Easily Treated

Here are some of the treatment options:


Topical antifungal creams applied a couple of times a day.

Oral Anti-Fungal Tablets

Taken daily or once a week if creams alone are not working.

Drying Agents

Potassium permanganate solution can be used with your doctor’s advice to reduce excessive moisture over the penis head and foreskin that encourages fungal growth.

Are there factors that may put me at greater risk of developing fungal balanitis?

Yes. You are at greater risk if you:

• are uncircumcised
• have poor hygiene
• are taking antibiotics for a long time
• have diabetes
• are overweight

Is fungal balanitis an early sign of diabetes?

Yes, balanitis can often be one of the first ways diabetes presents itself. Ask your doctor for a diabetes check, especially if your fungal infections are recurrent and if you have existing risk factors like a strong family history of diabetes.

Are there other penile skin rashes that can look like fungal balanitis?

Yes! If your condition is persistent, recurrent and the symptoms are never resolved completely, you could have an inflammatory skin condition known as Lichen Sclerosus.

Can an inflammation balanitis become more complicated?

Yes, it can cause chronic skin changes that do not allow the foreskin to function normally. The foreskin becomes no longer smooth and retractable, and it may also harden, thicken, become discoloured and have cuts.

When I first saw Dr Jess for my issue, I was afraid and apprehensive. Moreover, I wasn't exactly keen in talking to a female doctor as I wasn't sure if she would judge me or be empathetic towards my case. I soon realised that I could not be more wrong. What made the difference was that she was extremely patient and took the time to listen to me, and would sort out every single one of my concerns. She conducts her clinical sessions with extreme professionalism and I always feel comfortable around her. The best part was that she was never judgemental, and never made me incur any unnecessary costs. There are many doctors out there, but most do not take the time to really hear their patients out. I would highly recommend her if you are on the fence about seeing a doctor for your condition, because Dr Jess is a medical practitioner who truly cares about her patients' well being!

Dr. Jess is that excellent (and very rare) combination of big-hearted warmth and extreme clinical competency. She's interested and curious, has a deep desire to help, and always remembers what we discussed and done in the past. Also, her new space is comfortable and beautiful! I can't overrecommend this experience... check it out!

I'd spent a while trying to find a general practitioner in Singapore with some very, very mixed results (although I will admit to being a difficult patient sometimes). Dr. Jess was recommended to me when I suffered an acute condition and I can't believe how lucky I am to have found her when I did. She has that fantastic ability to be both amazingly friendly and approachable whilst still being incredibly knowledgeable, professional and focused on getting the best outcome possible for your health needs at the same time. As someone who has a background history in medical research and teaching medical students, I'm constantly impressed with the way Dr. Jess has always used both trusted, conservative methods whilst also being up to date with new techniques and the latest knowledge, and will research for answers and present it in a manageable, down-to-earth and tailored way - or recommend excellent specialists when required. I cannot recommend her highly enough, and she would be my doctor of choice no matter where I lived in Singapore. Also worth mentioning is that her staff are always very polite, friendly, competent and go out of their way to be helpful. I don't write reviews very often, but five incredibly well deserved stars.
