Final answer:
Orchiopexy is the surgical procedure to place and fix a testicle in the scrotum, often used to treat undescended testes.
Step-by-step explanation:
The procedure that involves the surgical placement and fixation of a testicle in the scrotum is known as an Orchiopexy. This surgery is typically performed to correct cryptorchidism, which is a condition where one or both of the testes have not descended into the scrotum as expected during fetal development or infancy. An Orchiopexy is recommended to facilitate normal development, to lower the risk of testicular damage, and to reduce the risk of future medical conditions, such as testicular cancer.
