Top 4 Scrotal Asymmetry Causes

  1. 1.Undescended Testicle (Cryptorchidism)

    Undescended testicle (cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging below the penis (scrotum) before birth. Usually just one testicle is affected, but about 10 percent of the time, both testicles are undescended.

    You should go see your pediatrician, who can diagnose undescended testes with a physical exam. Treatment involves surgery to place the testicles into the scrotum.

    Rarity:
    Rare
    Top Symptoms:
    scrotal asymmetry
    Symptoms that always occur with undescended testicle (cryptorchidism):
    scrotal asymmetry
    Urgency:
    Primary care doctor
  2. 2.Intermittent Testicular Torsion

    Testicular torsion occurs when the testicle rotates which cuts off the testicle's blood supply. This causes severe pain and swelling. In the case of intermittent testicular torsion, the testicle de-rotates itself and symptoms resolve.

    Intermittent testicular torsion resolves itself; however, it is likely to happen again and could be more severe. Talk with your doctor about an elective surgery than can permanently fix this problem.

    Rarity:
    Rare
    Top Symptoms:
    nausea, vomiting, testicle pain that comes and goes, pain in one testicle, testicular swelling
    Symptoms that always occur with intermittent testicular torsion:
    testicle pain that comes and goes
    Urgency:
    Primary care doctor

  3. 3.Epididymitis

    Epididymitis is swelling (inflammation) of the epididymis, a tube that sits on top of the testicle and is involved in making sperm. Most cases of inflammation are due to an infection.

    You should visit your primary care physician within the next 24 hours in order to find out the cause of the infection. If the cause is bacterial, which is common in this condition, antibiotics are prescribed.

    Rarity:
    Common
    Top Symptoms:
    nausea, fever, chills, vomiting, pain in one testicle
    Urgency:
    In-person visit
  4. 4.Testicular Torsion

    Testicular torsion occurs when the testicle rotates which cuts off the testicle's blood supply. This causes severe pain and swelling.

    Testicular torsion is likely to require emergency surgery. You should go to the nearest ER.

    Rarity:
    Rare
    Top Symptoms:
    nausea, vomiting, testicle pain, pain in one testicle, testicular swelling
    Symptoms that always occur with testicular torsion:
    testicle pain
    Urgency:
    Hospital emergency room
