Itching in the groin is caused by a wide variety of reasons. However, in most cases, it’s due to benign causes and can be solved with simple home remedies. However, sometimes it’s necessary to use certain drugs to solve the problem definitively.

Although itching leads to scratching the area, it’s best to avoid this action so as not to worsen the irritation. Instead, it’s advisable to determine what triggers the symptom in order to find the best treatment. So, what are the possible causes? Let’s take a look at the 10 most common reasons.

10 reasons for an itchy groin

Often, groin itching is caused by factors that can be controlled or eliminated without a problem. Other times, there’s a slightly more serious condition, such as an infection.

1. Hair removal and hair growth

It’s common for waxing or shaving to result in some degree of irritation in the area. This leads to an itchy groin. On the other hand, as soon as the hair begins to grow back, one or more pores may become clogged, which intensifies the itching.

2. Reasons for an itchy groin: Scratches

There are some activities that lead to the skin rubbing against each other, usually in the thigh area. These are activities where there is friction, such as running.

Sometimes, this disrupts the skin barrier and leads to small cracks appearing. This is followed by a rash that burns and itches. Peeling is also possible.

3. Problems with underwear

There are some undergarments, especially synthetic ones, that cause irritation and itching. This is because they’re often made of materials that make it difficult for the skin to breathe and accumulate perspiration. In fact, their use can cause small blisters, redness, and flaking.

4. Reasons for an itchy groin: Contact dermatitis

Contact dermatitis is related to the previous point. However, an allergic reaction can also occur from the components of detergents used to wash underwear or from the use of chemicals in the area.

5. Intertrigo in the groin

Intertrigo is an inflammation that occurs in the skin folds and is more common among overweight people. It’s caused by moisture and the presence of microorganisms in these areas. When the area is very humid, the skin breaks down and produces a bad odor. It usually causes itching and discomfort.

6. Mycosis

Mycosis is the most common cause of itching in the groin. This name is given to infections caused by fungi. The most common is tinea cruris or jock itch. This condition is more common in people who engage in frequent physical activity. It causes a red or brown spot, itching, and scaling.

7. Reasons for an itchy groin: Candidiasis

This is an infection caused by the Candida fungus. It often causes itching in the intimate area and groin. It also causes other symptoms such as redness, inflammation, the presence of whitish discharge (in both women and men), and pain during sexual intercourse.

8. Pubic lice

Pubic lice are parasites that settle in the hair and cause intense itching in the groin. In fact, this is the main symptom. There may also be white or yellowish spots at the base of the hair due to their eggs. They’re caused by poor hygiene or by sharing intimate clothing or towels.

9. Reasons for an itchy groin: Herpes

Genital herpes is a sexually transmitted disease. In addition to causing itching in the groin, it causes burning, irritation, and small blisters. As detailed in a publication in the National Center for Biotechnology Information, it’s caused primarily by herpes simplex virus type 1 or type 2. This may be a primary or recurrent infection.

10. Genital warts

Genital warts usually cause mild itching. Their presence is a common symptom of human papillomavirus (HPV). The lesions are usually soft to the touch and are cauliflower-shaped. They have the same color as the skin and are quite contagious.

What to do to soothe an itchy groin

Treatment for an itchy groin depends on its cause. Whatever the reason, it’s best not to scratch it, as this can exacerbate the problem or complicate it.

If you’re not sure what is causing it, the best thing to do is to see a doctor to establish the cause. In case of infection, the professional can prescribe drugs depending on the microorganism responsible (antifungals for fungi or antibiotics for bacteria, for example).

In general, medications come in the form of creams, ointments, or gels for topical use. However, they’re sometimes reinforced with oral treatments, especially for infections such as candidiasis or herpes. Antihistamines are also commonly prescribed to reduce the itching sensation.

What to remember about an itchy groin

Experiencing groin itch is uncomfortable and may alert the presence of an infection. If the symptom doesn’t improve by itself in a short period, it’s best to seek medical advice for a diagnosis. Depending on its origin, the use of topical or oral medications may be necessary.

In addition, it’s advisable to complement it with self-care measures, such as good hygiene, wearing cotton underwear, a good diet, and the elimination of irritating substances.
