What does it mean when a man has groin hernia?

Weak muscular ring: Weak muscular support in groin allows intestine to bulge through. Can stay stable for long time, or progressively get larger. May have no symptoms; often feels "heavy", with a bulge. Rx: elective surgery problem if intestine gets stuck and hernia can not be reduced, rx: urgent surgery; bigger problem if intestine twists on self and cuts off blood supply, rx: emergency surgery. No surgery?-truss.

Inguinal hernia: Direct inguinal hernia is due to weakness or defect of abdominal wall muscles in the groin area - subject may always feel need to push it back. Not dangerous but uncomfortable. Indiect inuinal hernia is due an outpouching of the periteum (abdominal lining) alongside the testicular blood vessels and vas (sperm duct). These have a relative narrow neck, bowel can enter, get stuck and strangulate. Fix.

Groin hernia: In the lower abdomen just before the leg crease, there is an area commonly called the groin. The groin (or inguinal) region is usually strong with muscle and tendon, but has potential for weak areas. A hernia is a protrusion or bulge through one of those weak areas, thus the term 'groin hernia'. A synonym is 'inguinal hernia'.

Hole: There's a hole in the abdominal wall muscles through which abdominal contents can protrude. Best to see a doctor for an exam and more information. That's the best way to make the diagnosis anyway - physical exam. Hope this helps!
