Genital itching in men is more common than many people realize, and it can range from mildly uncomfortable to seriously disruptive. It may be caused by something as simple as a skin irritation, or it may point to an infection or another condition that needs medical attention. This article explains the most common causes, how to treat them, and what you can do to prevent the problem from coming back.
What Causes Genital Itching in Men?
There are many possible reasons why a man might experience itching in the genital area. Some causes are non-infectious, while others involve bacteria, fungi, or sexually transmitted infections (STIs). Identifying the right cause is the first step toward the right treatment.
In some cases, the itch has no obvious cause at all. However, a proper assessment by a healthcare provider can usually get to the bottom of it.
Skin Irritants and Allergies
Everyday products can trigger irritation or an allergic reaction in the genital area. These include soaps, body washes, shaving gels, lubricants, perfumes, and laundry detergents. Some men also react to latex condoms in a similar way to a standard allergy.
In these cases, the solution may be straightforward. Switching to fragrance-free, hypoallergenic products and avoiding the irritant is often all that is needed to clear up the itch. Look for products labelled “sensitive skin” at your local pharmacy.
Fungal Infections: Jock Itch and Yeast Infections
Fungal infections are one of the most common causes of genital itching in men. Jock itch (tinea cruris) is a fungal infection that affects the groin, inner thighs, and genitals. It tends to appear as a red, ring-shaped rash and is more common in teenagers and active adults who sweat frequently.
Jock itch is easy to treat with over-the-counter antifungal creams or ointments. Doctors also recommend washing towels and bed linens regularly, wearing loose-fitting clothing, and keeping the genital area dry and clean.
Another common fungal condition is candidiasis, sometimes called a yeast infection or balanitis when it affects the head of the penis. Antifungal creams applied directly to the area are usually effective. In more persistent cases, a doctor may prescribe oral antifungal medication.
Scabies
Scabies is a contagious skin condition caused by tiny mites that burrow into the skin. It spreads through close skin-to-skin contact, including sexual contact. Scabies often affects the whole family, not just one person.
Symptoms include intense itching, especially at night, along with small red bumps or a rash that can spread to other parts of the body. Prescription treatments are available through your family doctor or a walk-in clinic. All household members and close contacts typically need to be treated at the same time to prevent re-infection.
Pubic Lice
Pubic lice, sometimes called crabs, are tiny parasites that attach to coarse body hair. They spread mainly through sexual contact. In fact, approximately 90% of cases result from direct sexual contact with an infected partner.
Symptoms include extreme itching and small skin sores caused by louse bites. Treatment involves topical medications designed to kill the parasites. You should also avoid sharing clothing, towels, or bed linens with anyone who is infected.
Sexually Transmitted Infections That Cause Genital Itching
Several STIs can cause genital itching in men. Two of the most well-known are herpes and trichomoniasis. Both are transmitted through sexual contact and require proper diagnosis and treatment by a healthcare provider.
If you are sexually active and develop genital itching alongside sores, discharge, or pain, it is important to get tested. Many sexual health clinics across Canada offer confidential STI testing, often covered under your provincial health plan. You can also visit a walk-in clinic or speak with your family doctor.

Non-Infectious Skin Conditions That Cause Genital Itching
Not all genital itching comes from an infection. Several chronic skin conditions can affect the genital area as well.
Psoriasis
Psoriasis is an autoimmune condition that causes patches of thick, scaly skin. When it affects the genital area, it can cause significant itching and discomfort. It is not contagious. Treatment usually involves medicated creams prescribed by a dermatologist.
Eczema and Atopic Dermatitis
Eczema, also known as atopic dermatitis, causes the skin to become dry, red, and intensely itchy. It can flare up anywhere on the body, including the genital area. Triggers include stress, certain fabrics, sweat, and harsh soaps.
Managing eczema typically involves moisturising the skin regularly, avoiding known triggers, and using prescription or over-the-counter hydrocortisone cream during flare-ups.
Lichen Simplex Chronicus
This condition develops when repeated scratching causes the skin to thicken over time. The more you scratch, the itchier the skin becomes, creating a difficult cycle to break. A doctor can recommend treatments to interrupt this itch-scratch cycle.
Precancerous Changes and Cancer
In rare cases, persistent genital itching may be linked to precancerous skin changes or cancer. This is uncommon, but it is another reason not to ignore itching that does not improve. A doctor can perform a proper examination to rule out serious causes.
How to Treat Genital Itching in Men
The right treatment for genital itching in men depends entirely on the underlying cause. This is why getting a correct diagnosis is so important before reaching for any remedy.
Common treatments include:
Antifungal creams or oral antifungal medications for fungal infections
Antibiotic creams or oral antibiotics for bacterial infections
Topical hydrocortisone cream to reduce inflammation and itching
Medicated shampoos or washes for lice or scabies
Antihistamines to temporarily relieve itching (these treat the symptom, not the cause)
Calamine lotion to soothe irritated skin and reduce the urge to scratch
A cold compress applied gently to the area to ease swelling and itching
One common mistake men make is assuming the itch is due to poor hygiene. As a result, they wash the area more aggressively and more often. This actually makes things worse, as it strips away the natural oils that protect the skin. Gentle, routine cleaning is enough.
Always speak with a doctor or pharmacist before combining over-the-counter products with prescription medication. Some combinations can reduce the effectiveness of your prescribed treatment.

How to Prevent Genital Itching
Prevention plays a big role in avoiding the discomfort of genital itching. Many cases can be prevented with simple daily habits.
Wash the genital area gently with a mild, fragrance-free, hypoallergenic soap. Rinse thoroughly with water.
Keep the area dry. Moisture encourages fungal and bacterial growth.
Wear underwear made from natural fibres, such as cotton, to allow the skin to breathe.
Change your underwear every 24 hours.
Use fragrance-free laundry detergent when washing underwear and rinse it well.
Dry off thoroughly after swimming or exercising.
Avoid staying in wet or damp clothing for long periods.
Use protection during sexual activity, and avoid sexual contact if you or your partner suspects an infection.
These steps are simple but effective. Consistency matters more than any single action.
When to See a Doctor
Many cases of mild genital itching will clear up on their own or with a basic over-the-counter remedy. However, you should see a doctor if the itching is severe, lasts more than a week, or comes with other symptoms such as a rash, sores, swelling, discharge, or pain.
In Canada, you have several convenient options. You can book an appointment with your family doctor, visit a walk-in clinic, or contact a sexual health clinic in your area. Most provincial health plans cover these visits. If you are unsure where to go, calling 811 (HealthLink in many provinces) connects you with a registered nurse who can advise you.
Do not delay seeking care out of embarrassment. Genital itching can sometimes indicate a condition that, if left untreated, may lead to complications. These include secondary skin infections, the spread of an STI to a partner, or, in rare cases, the progression of a more serious condition.

Frequently Asked Questions
What are the most common causes of genital itching in men?
Genital itching in men is most commonly caused by fungal infections like jock itch or yeast infections, skin irritants such as soaps and detergents, sexually transmitted infections, or chronic skin conditions like eczema or psoriasis. Scabies and pubic lice are also possible causes. A doctor can help identify the exact cause and recommend the right treatment.
Is genital itching in men always a sign of an STI?
No, genital itching in men is not always caused by a sexually transmitted infection. Many cases are linked to non-infectious conditions such as allergies, fungal infections, eczema, or psoriasis. However, if you are sexually active and notice other symptoms like sores or discharge, it is worth getting tested at a clinic or through your family doctor.
Can I treat genital itching at home without seeing a doctor?
Mild cases caused by irritation or a minor fungal infection may respond well to over-the-counter antifungal creams or switching to gentler hygiene products. However, if the itching persists for more than a week, is severe, or comes with other symptoms, you should see a healthcare provider. Treating the wrong cause can make the problem worse.
How do I know if I have jock itch?
Jock itch typically appears as a red, ring-shaped rash in the groin, inner thighs, or genitals, and it is usually accompanied by itching and a burning sensation. It is caused by a fungal infection and is more common in men who sweat heavily or wear tight clothing. A pharmacist or doctor can confirm the diagnosis and recommend an antifungal treatment.
Does poor hygiene cause genital itching in men?
Poor hygiene can be a contributing factor, but it is rarely the main cause of genital itching in men. In fact, washing too frequently or too aggressively can strip the skin of its natural protective oils and make itching worse. Gentle, regular cleaning with a mild, fragrance-free product is the best approach.
Where can I get help for genital itching in Canada?
In Canada, you can speak with your family doctor, visit a walk-in clinic, or contact a sexual health clinic in your area. Most provincial health plans cover these visits. You can also call 811 to speak with a registered nurse who can offer guidance on next steps.
