MeSH Heading: Cryptorchidism
Tree Number(s): C12.100.500.829.258; C12.200.294.829.258; C12.200.706.258; C12.800.258; C16.131.939.258; C19.391.829.258
Unique ID: D003456
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D003456
Scope Note: A developmental defect in which a TESTIS or both TESTES failed to descend from high in the ABDOMEN to the bottom of the SCROTUM. Testicular descent is essential to normal SPERMATOGENESIS which requires temperature lower than the BODY TEMPERATURE. Cryptorchidism can be subclassified by the location of the maldescended testis.
Entry Term(s): Abdominal Cryptorchidism; Bilateral Cryptorchidism; Cryptorchidism, Unilateral Or Bilateral; Cryptorchism; Inguinal Cryptorchidism; Testes, Undescended; Testis, Undescended; Undescended Testis; Unilateral Cryptorchidism
