What it is, and its many namesStrong evidence
Sports hernia is a name for pain in athletes around the inguinal canal, the passage just above the groin crease, with tenderness there and no lump. An international agreement on groin pain in athletes (the Doha agreement) calls it inguinal-related groin pain: pain in that area, tender to touch, with no hernia you can feel, and more likely if a resisted sit-up, coughing, sneezing or straining brings it on. It recommends dropping the names sports hernia, sportsman's hernia, athletic pubalgia and Gilmore's groin, and a 2026 European consensus keeps its terms.
A UK consensus prefers inguinal disruption and says no true hernia exists. It describes too much tension around where the inguinal ligament attaches, sometimes with small tears in the external oblique, one of the side tummy muscles. Another name you'll see is core muscle injury.

How it differs from a true herniaStrong evidence
A true inguinal or femoral hernia is tissue or bowel pushing through a weak spot. It causes a bulge in the groin or upper thigh that may get bigger when you cough, sneeze or strain and smaller when you lie down, sometimes with a heavy, dragging feeling. Femoral hernias mainly affect women over 50, often become trapped, and need surgery.
A sports hernia has no lump. The American Academy of Orthopaedic Surgeons (AAOS) says that over time a sports hernia may lead to an inguinal hernia; we found no figures on how often.

Other causes of groin pain, and how often they overlapEmerging evidence
Groin pain in athletes has several defined types. Pain at the inner thigh or pubic bone, worse squeezing the knees together, is adductor-related and is the commonest: the main problem in 58% of 207 athletes (69% of footballers) at one clinic, and present in 61% of 100 athletes at another. Pain at the front of the hip when lifting the knee is iliopsoas-related; a deep pinch when bending the hip is hip-related; and groin pain in a runner that hurts with every step can be a stress fracture. Each has its own guide.
Overlap is common: a third of the 207 athletes, and 44% of the 100, had more than one source of pain. Among athletes who needed groin surgery, the commonest diagnoses were hip impingement (32%), athletic pubalgia (24%), adductor problems (12%) and inguinal problems (10%).

Who gets itEmerging evidence
It's commonest in sports with sudden changes of direction and hard twisting, such as football, ice hockey, rugby and wrestling. In elite contact-sport teams followed for 2 years, long-standing groin pain of any kind affected 7.5% of players a year.
Nearly all the research is in men: 98 of the 100 athletes and 196 of the 207 were male, and the Pilates trial enrolled only men. Women with groin pain should also be checked for a femoral hernia, hip problems and pelvic causes (our suggestion).

How it's recognised, and what scans showEmerging evidence
The diagnosis comes from your story and an examination: pain and tenderness over the groin canal, and pain with a resisted sit-up, coughing or sneezing. No single test is perfect. In a study of 44 male athletes, how well two examiners agreed on the tests ranged from slight to substantial, and the commonest positive finding was the athlete's usual pain when the examiner pressed into the groin canal through the scrotum while the athlete strained (79%). A 2026 European consensus says this check should be part of every routine examination.
Scans are a poor guide on their own. Up to 71% of footballers without pain had findings on MRI (magnetic resonance imaging), and swelling in the pubic bone was nearly as common in players without pain (47%) as in those with it (53%). Ultrasound is the first scan when a true hernia is suspected; no scan finding defines a sports hernia.

How it usually goesEmerging evidence
With structured rehab, 73% of 205 athletes with long-standing groin pain of mixed types (they'd had it for a median of 32 weeks) returned to sport pain-free, on average about 10 weeks later. The AAOS says 4 to 6 weeks of physiotherapy settles many cases. No good study has followed people without treatment.
