Scrotal Swelling

Scrotal swelling may occur on one or both sides of the scrotum. Pain may also occur with swelling. Possible causes of scrotal swelling include:

  • Injury.

  • Infection.

  • An ingrown hair or abrasion in the area.

  • Repeated rubbing from tight-fitting underwear.

  • Poor hygiene.

  • A weakened area in the muscles around the groin (hernia). A hernia can allow abdominal contents to push into the scrotum.

  • Fluid around the testicle (hydrocele).

  • Enlarged vein around the testicle (varicocele).

  • Certain medical treatments or existing conditions.

  • A recent genital surgery or procedure.

  • The spermatic cord becomes twisted in the scrotum, which cuts off blood supply (testicular torsion).
