Final answer:
Orchiopexy is the medical procedure for the fixation of an undescended testicle, necessary for proper testicular positioning and to reduce potential health risks.
Step-by-step explanation:
Orchiopexy refers to the surgical procedure known as c. fixation of an undescended testicle. This medical intervention is designed to address a condition called cryptorchidism, where one or both testicles fail to descend into the scrotum naturally. The successful performance of orchiopexy allows the testicles to be correctly positioned within the scrotum, which can be essential for both fertility and the reduction of other health risks associated with undescended testicles.
