In the lower part of the abdomen, there are natural openings to allow blood vessels and sperm (in men) to travel through the abdominal wall. This opening and the space around it are a weak link in our abdominal wall. over time, the tissues can stretch, leading to a condition in which the abdominal contents protrude through this weakness, leading to an inguinal hernia. One in four men will get an inguinal hernia in their lifetime and one in four of those men will get hernias on both sides. Women are much less likely to develop inguinal hernias than men.
