Introduction: Placenta is a functional unit between the mother and the foetus. Human placenta is discoid, deciduate, haemochorial, chorioallantoic, labyrinthine and endocrine gland which connects developing embryo by umbilical cord to the endometrium of mother’s uterus. It develops from two sources. Material and Method: This is a prospective study conducted at Department of Anatomy and Physiology, at Tertiary Care Teaching Hospital over a period of 1 year. Inclusion Criteria: Totally, 70 healthy mothers who gave birth to uncomplicated singleton pregnancy, and their new-borns were included in the study. Exclusion Criteria: Subjects with diabetes mellitus, hypertension, anaemia, vascular diseases and multiple pregnancies were excluded in this study. Result: The New-born body mass index (Kg/m2) was measured and the majorities (55.7%) of the new-born were within 11-13 followed by 25.7% of the new-born were more than 14 and the lesser proportion of 18.5% was <10 BMI (Kg/m2). The mean placental weight (in gms) for the female babies <10 BMI (Kg/m2) were 386.62±45.72. The Mean placental weight (in gms) for the male and female babies of BMI 11-13 (Kg/m2) were 398.53±43.74 and 478.63±49.48 respectively. The mean placental diameter (in cms) for the female babies of <10 BMI (Kg/m2) were 14.64±1.23. The mean placental diameter (in cms) for the male and female babies were 15.64±1.53 and 16.64±1.42 respectively of BMI of 11-13 (Kg/m2). Moreover, mean placental diameter (in cms) for the male and female babies were 17.54±1.67 and 16.68±1.86 respectively of BMI of 11-13 (Kg/m2). Conclusion: This study confirms that morphometric observation of placenta is associated with foetal weight. So, an early examination of not only the fetus, but also the placenta by non-invasive techniques like ultrasonography will be helpful to predict and to avoid low birth weight babies with better preventive measures. This study will also make the physicians and researcher to focus on the placenta.
