The success rates by surgical approach were as follows [60] :

  • Inguinal orchiopexy: 89%
  • Microvascular orchiopexy: 84%
  • Transabdominal orchiopexy: 81%
  • Staged Fowler-Stephens orchiopexy: 77%
  • Standard Fowler-Stephens orchiopexy: 67%

According to a study of 51 formerly cryptorchid subjects who had undergone surgery in the first 2 years of life, sperm count and motility were normal in more than 95% at 18-26 years of age, with even better fertility prognosis if orchiopexy was performed during the first year of life (96.3% for both normal sperm count and sperm motility). [61]  A systematic review and meta-analysis found that atrophy and complication rates do not appear different between orchiopexy performed before or after 1 year of age, but fertility potential may be better with early orchidopexy.
