Introduction: Placenta is the fundamental and the only organ between the mother and the fetus. It is flattened discoid mass having circular or oval in outline. Placenta and its morphometry play an essential role in the proper growth and survival of the developing fetus. Objective: To study the correlation between placental morphometry in Low birth weight and appropriate control with its gestational age. Materials and Methods: It is a case-control study conducted in MES Medical College at Perinthalmanna, Kerala, India. Newborns with normal (>2.5 Kg) and low birth weight (<2.5kg), having 35-37 wks (Preterm) also, 37-42 wks, (term) of gestational age were included. In this study, 350 placentae were collected, immediately after the delivery, wash thoroughly, cleaned, and trimmed it for the morphometric analysis like shape, weight, maternal surface area, volume, thickness. Result: In this study, placental morphometry of low birth weight babies was comparatively lower than that of the normal birth weight babies. Parameters like weight, volume, and surface area of the placenta were calculated with gestational weeks, showed a positive and significant relationship with weight at birth and gestational age. Conclusion: The examination of the placenta can be helpful for the future postnatal life and resist early adulthood diseases of the neonates.
