Most common side for indirect inguinal hernia is which side?

• A. Right
• B. Left
• C. Bilateral
• D. Either side equally

Answer: (A)

Indirect inguinal hernias are congenital defects caused by a persistent processus vaginalis, producing a peritoneal sac that enters the inguinal canal lateral to the inferior epigastric vessels and travels within the spermatic cord. The side predominance comes from embryology: the processus vaginalis closes later on the right side than on the left, so the right side remains patent more often and is more prone to herniation. Although left-sided and even bilateral cases occur, they are less common than right-sided ones.
