Surgical treatment of cryptorchidism of right testis with normally descended left testis can be done?

Ans. is 'None' "The congenital undescended testis should be treated surgically no later than 9-15 months. Surgical correction at 6 months is appropriate". - Nelson Impoance of age at orchidopexy A) Why after 4 months o The majority of the undescended testes descent spontaneously during first 3 months. So, orchidopexy should be done at 6 months, because spontaneous descend of the testis will not occur after 4 months of age. B) Why before 2 years 1. To prevent infeility Undescended testis is normal at bih histologically, but pathological changes develop by 6-12 months that results in infeility. So best time of orchidopexy is around 6 months, before the development of pathologic changes. 2. To prevent malignancy -> It is uncommon for testis tumors to occur after orchidopexy performed before the age of 2 years.
