Pimples on the scrotum may result from a buildup of dead skin, an infection, ingrown hair, and other issues. Possible treatments and preventive tips include good hygiene practices, applying a cool flannel, and wearing loose clothing.
The scrotum is the sack beneath the penis that holds the testes. Sweat and moisture often build up in the groin area and clog pores, leading to pimples. Heat and friction can also contribute to pimple formation. Pimples can cause discoloration, a raised area of skin, pus, or sometimes all three.
This article covers the different types of pimples, their causes and treatments, and how a person can prevent them.

Pimples can form in almost any area of the body and typically occur due to pore blockages, resulting from:
- dead skin cells
- dirt
- sweat
- natural body oils
Depending on a number of factors, pimples may appear in different forms, including:
- Blackheads, which form when oil clogs a pore and the air turns it black.
- Whiteheads, which form the same way but remain white as the top of the pore is closed.
- Papules or discolored bumps that often feel sore when touched.
- Pustules that have a white tip in their center caused by pus building up.
- Nodules or bumps below the surface of the skin, which are often painful.
Besides blocked pores, there are several other reasons for discolored spots on the scrotum.
Ingrown hair
Ingrown hairs are a common cause of discolored bumps in the pubic region. This happens when a hair twists and grows back into the skin. It usually creates a spot that can cause itching or discomfort.
Pubic hair is usually curlier and coarser than the hair on the head, and this type of hair is more likely to become ingrown. Shaving also increases the risk of hair growing inwards.
Folliculitis
Folliculitis is a skin disorder typically involving infection and inflammation of hair follicles. The hair follicles may swell up and fill with pus, and often appear in a cluster, resembling pimples.
Heat rash
Heat rash can affect the skin in warm weather. It appears as small, discolored spots and usually causes itching or prickling.
Sweating can irritate the rash, so keeping the skin cool can help with symptoms.
Sexually transmitted infections (STIs)
Some sexually transmitted infections, or STIs, can cause spots to form on the scrotum:
- Herpes causes small blisters to appear on the skin.
- Syphilis is now a fairly uncommon STI, but it can cause a sore on the skin.
- Pubic lice, also known as crabs, can cause a rash of small bumps.
Molluscum contagiosum
Molluscum contagiosum is a virus that affects the skin. It is more
The main symptom is small, raised spots that are firm to the touch. They form in clusters, usually in creases around the body, such as the armpits and groin.
If pimples appear on the scrotum repeatedly or last for more than a week, people may wish to seek medical advice. Pimples that appear in clusters or look like a rash can be a virus or infection that needs treatment.
If someone has symptoms of an STI, they should see a doctor. Symptoms can include itching, fever, pain when urinating, and discharge from the penis.
Pimples often do not need any treatment and often resolve independently.
However, it is important to keep areas of irritation and inflammation clean and dry. Using chemicals on the body can irritate pimples. The skin should be kept clean and dry, using warm water and gentle soap for washing.
Do not pick or scratch a pimple, as this can damage it. A pimple that has burst or bled is more likely to become infected.
Pimples caused by an infection or virus may need treatment. A doctor can advise on the right course of action.
Other conditions
Ingrown hair should often be left alone, as it will usually work its way out of the hair follicle naturally. Folliculitis also typically does not need treatment, but if it lasts for more than a week, a person should see a doctor.
A person can often treat heat rash at home by:
- applying a cool, wet flannel to skin to soothe irritation
- having a cool shower or bath
- wearing loose-fitting clothing
- staying hydrated by drinking plenty of fluids
If a person has an STI, they may need to take a course of antibiotics. Abstaining from sexual contact until the infection clears will prevent it from spreading to others.
Good hygiene can help prevent pimples. Wearing clean underwear and showering every day can help prevent pimples from developing. Taking a shower after exercise or sweating a lot can help prevent sweat from clogging pores, which can lead to pimples.
Loose-fitting underwear made from natural fabrics can stop heat and moisture from building up. If pimples are caused by ingrown hairs, avoiding shaving can prevent them from developing. Hair removal cream is less likely to cause ingrown hairs than shaving.
Most pimples are harmless and will usually go away on their own. Anyone with recurrent pimples on the scrotum should consider seeing a doctor or take preventive measures.
People who have symptoms that may indicate an STI should see a doctor for a diagnosis.
