Abstract: Introduction: Morphometric measurements including the weight of foetal spinal cord is helpful in determining the age and sex of foetuses, which are of great medicolegal significance. The aim of present study is to obtain accurate measurements of weight of human foetal spinal cord in different age groups. Material and Methods: Foetuses without any congenital cranio-vertebral anomalies were selected for the study and divided into five groups on the basis of gestational age. Laminectomy was performed and the spinal cords from human foetuses were taken out and weight recorded on electronic weighing machine under standard conditions. Result & Conclusion: Significant gain in weight of foetal spinal cord was observed in successive adjacent groups from group II onwards and maximum gain in weight was observed between group III and IV.
