Background: Autopsy (necropsy, post mortem examination, thanatopsy) is the examination of a person’s body after death. An autopsy is of different types. But among them Medicolegal autopsy is the concern of the forensic pathologist in India. Study of weight of human body organs plays a significant role in almost all the branches of medical sciences including forensic medicine, as any deviation in weight from the normal range suggests some pathological change in the organ. Recording of organ weights is one of regular criteria by the forensic experts during an autopsy. The findings were compared to what is standard or average of a specific organ for a specific age range and particular sex. The determination of weights of abdominal organs in particular has significant clinical value. Materials and Methods: After getting institutional ethical committee clearance, the study done over the body of the 570 deceased came for medicolegal autopsy fulfilling the inclusion and exclusion criteria. Results: Total 570 cases were selected after following the inclusion and exclusion criteria out of which 362 were males and 208 were females. Among the studied 570 cases, 362 (63.5 %) were male and 208 (36.5 %) were female. In this study the discussion was mainly on relation of age, sex, body weight, and body length upon the weights of thoracic viscera. Conclusion: A database can be formed from this study regarding normal range of the weight of various organs and their relation with external parameters of the subjects which can be applicable on the population of this region for future reference. In severely mutilated bodies found in mass disasters or in homicidal killing, weights of isolated organs may give an idea about the stature, built and age of the victims helping in identification.
