The most common causes of pimples in your scrotum are dead skin cells and sweat. Sometimes, these pimples usually go away without treatment. Pimples in the scrotum usually appear one at a time, or in clusters. Clustering of pimples in your scrotum is usually as a result of; sweat, irritation from rubbing against your clothing, moisture buildup, friction with other parts of the body for a long time.

However, the primary cause of pimples is pores that are blocked by the following:

Ingrown hairs are easily the most common cause if pimple on the scrotum. This usually happens when a hair twists and grows back into the skin. It creates a red spot that can cause discomfort. An ingrown hair can happen when hair follicles get clogged with dead skin cells. This causes a hair to grow sideways or inward instead of outward. Pubic hair is usually curlier and coarser than the hair on the head, which makes it even more likely to become ingrown.

Ingrown hairs are more common on areas that have been shaved. If someone shaves the hair on or around their testicles, it may result in ingrown hairs.

  • Sexually transmitted infections (STI’s)
