Cryptorchidism

Introduction

  • Failure of testes to descend into the scrotum unilaterally or bilaterally
    • normally mediated by MIF + androgens
  • Testicle most commonly located in the inguinal canal
    • can also be intra-abdominal
  • Associated conditions
    • prematurity
    • Kallmann’s syndrome
    • cystic fibrosis
  • testicular feminization
Treatment
 Orchidopexy

Prognosis, Prevention, and Complications

  • Prognosis
    • most descend by 3 months
    • if natural descent does not occur by this time it must be removed surgically by 2 years
  • Complications
    • infertility
      • reduced spermatogenesis due to ↑ body temperature
    • atrophy/hyalinization of the seminiferous tubules due to ↑ body temperature 
    • testicular torsion
    • seminoma/germ cell cancers
      • ↑ risk of development
      • risk also applies to contralateral testicle even if it descended normally
