Cryptorchidism

Cryptorchidism is an abnormality of either unilateral or bilateral testicular descent, occurring in up to 30% premature and 3-4% term males. Descent may complete postnatally in the first year, failure to descend can result in sterility.

The cryptorchidism types are classified on whether the testis is located in the normal descent pathway (true) or in an abnormal location (ectopic) and then by the anatomical position of the testis.

Cryptorchidism Types
True Ectopic
  • abdominal
  • inguinal
  • suprascrotal
  • prepenile
  • superficial ectopic
  • transverse scrotal
  • femoral
  • perineal
