Cryptorchidism, unilateral or bilateralOMIM Phenotype
Preferred Label : Cryptorchidism, unilateral or bilateral;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Undescended testis;
Description : Cryptorchidism, or failure of testicular descent, is a common human congenital abnormality
with a multifactorial etiology that likely reflects the involvement of endocrine,
environmental, and hereditary factors. Cryptorchidism can result in infertility and
increases risk for testicular tumors. Testicular descent from abdomen to scrotum occurs
in 2 distinct phases: the transabdominal phase and the inguinoscrotal phase (summary
by Gorlov et al., 2002).;
Inheritance : Autosomal dominant;
