Outcome Measures

Primary Outcomes (2)

  • Sperm concentration

    Amount of motile sperm cells (\* 10\^6)

    8-17 years after surgical intervention

  • Testosterone level

    ng/ml

    8-17 years after surgical intervention

Secondary Outcomes (5)

  • Semen parameters as an indicator of overall testicular exocrine function

    8-17 years after surgical intervention

  • Hormone level as an indicator of testicular endocrine function

    8-17 years after surgical intervention

  • MAR test result correlated to the type of surgery

    8-17 years after surgical intervention

  • Difference in sperm morphology and motility correlated to the type of surgery and compared to control group

    8-17 years after surgical intervention

  • Paternity as a measure of fertility

    8-17 years after surgical intervention

Study Arms (2)

Testicular torsion group
