RESUMEN
AIM AND OBJECTIVES: Comparison of naturally conceived pregnancy with IVFET pregnancy for feto-maternal outcome and morphology and histopathology of placenta & umbilical cord. METHODS: 100 pregnant women were divided into 2 subsets of spontaneous pregnancy group (n = 50) and the IVFET pregnancy group (n = 50).The two groups were compared for Maternal age, parity, maternal weight gain, prepregnancy maternal BMI, gestational age, birth weight of baby, placental weight, placenta and umbilical cord cross sections, insertion site of the umbilical cord, and length of the umbilical cord. INCLUSION CRITERIA: Patients registered at ANC OPD/ART centre of our institute and subsequently reporting to maternity ward/ labor room for delivery at our centre. EXCLUSION CRITERIA: The pregnancies conceived after ART outside our institute, multifetal pregnancies. Study duration: 01 year Results: Our study revealed that spontaneous pregnancy group had less antenatal co-morbidities with more number of term vaginal deliveries and less intrapartum and neonatal complications compared to IVFET pregnancy women (p < 0.05). CONCLUSIONS: Assisted reproductive technologies have an impact on placental growth and function in pregnancy. The occurrence of placental abnormalities were the most significant and pertinent finding in the IVF-ET placentas. On histopathological examination maternal vascular malperfusion and concomitant anomalies of the umbilical cord were most noticeable findings.
