Testicle itching, although rather uncomfortable and possibly embarrassing, is often not a huge cause for alarm. An itchy testicle or groin area can be caused by a number of things, some of which are serious, but many of which are quite harmless. Some of the most common causes of testicle itching are a fungal infection, allergies, and certain types of bugs.

Tinea cruris, commonly known as jock itch, is typically caused by a fungus called Trichophyton rubrum. This type of fungus also causes athletes foot and thrives in warm, moist areas. Although it mostly happens among athletic men, women can also suffer from this kind of fungal infection.

Symptoms of this condition include intense crotch itch, especially on the testicles, inner thighs, and anus, accompanied by a red rash with scaly edges. The rash usually starts in the folds of the skin and spreads from there. Many times, all that's needed to get rid of jock itch is an over-the-counter topical spray or cream. If these do not clear up the itching and irritation, a visit to a physician's office is most likely in order.

If over-the-counter anti-fungal creams don't work, the testicle itching could be caused by a yeast infection, which is usually caused by Candida albicans, which is a type of fungus. Many people may not know it, but women are not the only ones who can get a yeast infection. Men can get one through sexual contact with an infected partner or from using antibiotics that kill off good bacteria. Symptoms of a male yeast infection include irritation, burning, itching, and pain in the groin area. Treatment usually consists of a topical anti-fungal cream and, possibly, an oral medication.

Another common cause of testicle itching is contact dermatitis. Symptoms of this condition often include discomfort, a rash, and itching in the groin area, including the scrotum. It is typically caused by direct contact with either an irritant or an allergen.

Irritant contact dermatitis is usually caused by an irritating substance, such as a strong chemical. It is generally more painful than allergic contact dermatitis and less itchy. Allergic contact dermatitis is quite common in individuals with other allergies, and can be caused by a number of things, including fragrance or dye in soaps, or certain plants, such as poison ivy. In this case, any known allergens should be avoided as much as possible.

Phthirus pubis, more commonly known as pubic lice or crabs, is an insect that feeds on human blood, especially in the genital regions. In men, the bites from these insects can cause intense testicle itching. These parasites are typically spread through sexual contact, but can also be passed on to a person via infested bedding, towels, or clothes. Many times, over-the-counter creams and soaps can be purchased to get rid of them, but sometimes, in severe cases, a prescription may be required.

Scabies is an itchy rash caused by Sarcoptes scabiei, or the itch mite. As these parasites seem to seek out warm folds in the skin, the genitalia is a common spot for infestation. Like with pubic lice, the bites and products of these insects can cause intense testicle itching.
