Kunnen je ballen in je buik komen?
Tijdens de zwangerschap ontwikkelen de teelballen zich in de buik, vlakbij de nieren. Ongeveer een maand voor de geboorte zakken de ballen via het lieskanaal in de balzak. Dit wordt indalen genoemd.
Is cryptorchidism unilateral or bilateral?
Cryptorchidism, unilateral or bilateral. Summary. 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.
What is cryptorchidism in males?
Cryptorchidism is the absence of one or both testes from the scrotum. It is the most common birth defect of the male genital. About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis.
Can you breed a dog with cryptorchidism?
Cryptorchidism can be either bilateral (causing sterility) or unilateral, and inguinal or abdominal (or both). Because it is an inherited trait, affected dogs should not be bred and should be castrated. The parents should be considered carriers of the defect and a breeder should thoughtfully consider whether to breed the carrier parent or not.
What is the rate of incidence of cryptorchidism?
It is the most common birth defect of the male genital tract. About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis. However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall.
