Which side is most commonly affected by indirect inguinal hernias?

Explanation:
Indirect inguinal hernias occur when the processus vaginalis fails to obliterate, leaving a persistent channel through which abdominal contents can protrude into the inguinal canal and often into the scrotum. The right-sided processus vaginalis tends to remain patent longer than the left, so right-sided hernias are more common. Left-sided hernias are less frequent, bilateral occurrences do occur but are not as common as unilateral right-sided cases, and the idea of equal likelihood is incorrect.
