What is Penis Infections?
Written by Medicover Team and Medically Reviewed by Dr Ravi Shankar Karupothula , Urologist
Penis infections are fairly common and can cause pain, swelling, itching, or discharge. These infections may result from bacteria, viruses, or fungi and are often linked to poor hygiene, unprotected sex, or other health conditions like diabetes.
What are the Types of Penis Infections?
Penis infections come in different forms, each caused by bacteria, viruses, or fungi. The type of infection affects the symptoms, treatment, and whether it's sexually transmitted or not. Identifying the specific cause helps guide the right care.
Balanitis
Balanitis is inflammation of the penis head, usually in uncircumcised men. It's often caused by poor hygiene, yeast, or bacteria.
- Symptoms: Redness, swelling, pain, and discharge under the foreskin
- Treatment: Cleaning, antifungal or antibiotic creams, managing diabetes
Urethritis
Urethritis is an infection of the urethra, commonly caused by STIs like chlamydia or gonorrhea.
- Symptoms: Pain when urinating, discharge, itching
- Treatment: Antibiotics and partner treatment
Yeast Infections
Caused by Candida yeast, often in men with diabetes or after antibiotics.
- Symptoms: Itching, redness, white discharge, rash
- Treatment: Antifungal cream, hygiene, keeping the area dry
Herpes and HPV (Viral Infections)
Herpes causes painful blisters; HPV causes genital warts.
- Symptoms: Sores, bumps, or warts on the penis
- Treatment: Antiviral or wart removal treatment, no permanent cure
Bacterial Infections
Result from cuts, sweat, or poor hygiene, not always sexually transmitted.
- Symptoms: Redness, pus, swelling, pain
- Treatment: Antibiotics, good hygiene, wound care
What Are the Symptoms and Warning Signs of a Penis Infection?
Symptoms may start mild but can quickly get worse if untreated. While some infections cause irritation or discharge, others may lead to sores, pain, or even fever. Knowing the warning signs can help you act early.
Common Symptoms
- Redness or swelling of the penis
- Pain, burning, or discomfort (especially when urinating or during sex)
- White, yellow, or foul-smelling discharge
- Itching or irritation on or under the foreskin

If you experience any of these symptoms, especially with fever or pain, see a doctor right away.
What Are the Main Causes and Risk Factors for Penis Infections?
Poor hygiene, unprotected sex, and excess moisture are some of the most common causes. Underlying health conditions like diabetes and immune suppression can also raise your risk. Understanding these causes can help you prevent recurring infections and protect your intimate health.
Common Causes
- Poor genital hygiene, especially under the foreskin
- Unprotected sex, which spreads bacterial and viral infections
- Excess moisture from sweating or tight underwear
- Minor skin injuries, like cuts or chafing
- Reactions to soaps or chemicals, like perfumed products
- Antibiotic use, which disrupts natural skin balance
- Friction or rough sexual activity
Risk Factors
- Being uncircumcised without proper cleaning
- Multiple sexual partners
- Diabetes, which weakens the immune defence
- Weakened immune system from HIV or medications
- Poorly ventilated underwear (tight, synthetic fabrics)
Avoiding these risks can lower the chance of infection and irritation.

Get Second OpinionHow is a Penis Infection Diagnosed?
Diagnosis is based on a physical exam along with lab tests like swabs, urine samples, or blood work. Doctors may look for bacterial, fungal, or viral signs depending on your symptoms. Accurate diagnosis ensures faster relief and avoids the wrong treatments.
Common Diagnostic Steps
- Physical exam to check skin changes, redness, or sores
- Swab test to check for bacteria, viruses, or yeast
- Urine test if urethritis is suspected
- Blood tests to check for STIs or related infections
- Skin scraping for fungal infections like Candida
Early diagnosis helps treat the infection quickly and prevent long-term damage.
What Are the Treatment Options for Penis Infections?
Most penis infections are treatable with medications like antibiotics, antifungal creams, or antivirals. Proper hygiene and lifestyle changes also play a key role in recovery. The treatment plan depends on the infection type and whether it's sexually transmitted.
Medical Treatments
- Antibiotics: For bacterial infections and some STIs
- Antifungal creams or tablets: For yeast infections (like balanitis or candidiasis)
- Antiviral drugs: For herpes or HPV symptoms
- Topical steroids: For irritation or allergic reactions
- Circumcision: Rarely needed, but may help with repeated infections
Self-Care and Hygiene Tips
- Clean the penis daily with mild soap and warm water
- Gently dry the area, especially under the foreskin
- Wear breathable cotton underwear
- Avoid harsh soaps, powders, or strong deodorants
- Drink plenty of fluids to flush the urinary tract
- Partner treatment may also be needed for STIs to prevent reinfection.
When Should You See a Doctor?
Sometimes, what looks like a simple rash can be something more serious. It's best to see a doctor if symptoms don't go away or get worse.
Seek Medical Help If You
- Have pain, itching, or swelling that lasts more than 2 to 3 days
- Notice discharge or sores on the penis
- Have trouble urinating or feel a burning sensation
- Had unprotected sex with a new or multiple partners
- Have a fever or swollen groin lymph nodes
- Keep getting infections repeatedly
Getting early care can stop complications like scarring or long-term discomfort.

What is the Recovery Process of Penis Infections?
With the right treatment, most penis infections heal within a few days to a week. Good hygiene and avoiding sexual activity until recovery are important for healing. Follow-up care helps ensure the infection is fully cleared and doesn't return.
Post-Treatment Care
- Finish all prescribed medication
- Keep the penis clean and dry
- Avoid sex until the infection is fully healed
- Return for follow-up if symptoms continue
- Watch for signs of reinfection, especially if you have an underlying condition like diabetes
With good care, most people recover fully and have no long-term problems.
Can Penis Infections Be Prevented?
Yes, most penis infections can be prevented with simple steps. Prevention is easier than treatment and helps avoid future complications.
Prevention Tips
- Wash the penis daily, especially if uncircumcised
- Avoid using strong soaps, powders, or sprays
- Dry the area completely after bathing
- Use condoms during sex
- Change out of wet or sweaty underwear promptly
- Manage diabetes and other health issues
- Avoid sharing towels or underwear
- Get regular STI screenings if sexually active
If you notice early signs of infection, act quickly before it gets worse.
What are the Possible Complications If Penis Infection Left Untreated?
Untreated penis infections can lead to serious problems like urinary issues, sexual dysfunction, or scarring. In some cases, infections may spread to the bladder or reproductive organs. Timely treatment is key to avoiding these complications.
Risks of Untreated Penis Infections
- Chronic pain or sensitivity
- Spread of infection to the urinary tract or other organs
- Scarring of the foreskin or urethra
- Sexual dysfunction
- Infertility (in rare, severe cases)
- Higher chance of spreading STIs to partners
