Complications

By Mayo Clinic staff

A boy with a retractile testicle may be vulnerable to these complications:

  • Testicular cancer. Testicular cancer usually begins in the cells in the testicle that produce immature sperm. What causes these cells to develop into cancer is unknown. Men who have had an undescended testicle have a greater risk of testicular cancer.
  • Fertility problems. Low sperm counts, poor sperm quality and low fertility rates are more likely among men who have had an undescended testicle.
  • Testicular torsion. Testicular torsion is the twisting of the spermatic cord. This painful condition cuts off blood to the testicle. If not treated promptly, it may result in the loss of the testicle. An undescended testicle increases the risk of testicular torsion.
