Abstract
Background: Postdated pregnancy is gestation longer than 40 weeks or 280 day. Prolonged pregnancy is defined as any pregnancy that last 294 days or more. Reported frequency of post term pregnancy range from 3 - 1 4 percent with an average of about 10 percent. Several studies have concluded that these pregnancies are accompanied by a rise in perinatal morbidity and mortality. The presumed etiology for this rise is placental insufficiency. Abnormalities such as congenital anomalies, oligohydramnios, meconium aspiration, fetal asphyxia, fetal dysmaturity, macrosomia and shoulder dystocia are commonly observed in these pregnancies
 Materials and Methods: This study was conducted in the Department of Obstetrics and Gynecology, after approval from the Ethics Committee, from January 2019 to September2020 on 150 patients in the department of Obstetrics and Gynaecology, willing to participate and fulfilling the inclusion and excliusion criteria in the study period.
 Results: Of the total 150 women, 122 (81.34%) were in 40 weeks group; 28 (18.66%) in 41 weeks group and 0 (0%) were in > 42 weeks group. Most women (89.3%) were between 20-35 years of age. Among 150 women, 40 (26.6%) went into spontaneous labor, 87(8.0%) were induced andn23 (15.34%) was taken for caesarian section. Misoprostol, Dinoprostone gel and oxytocin were the different modes of induction (Table 7). Misoprostol was used in the majority of inductions followed by Dinoprostone gel. The success rate between these two is almost similar (92.45% & 95.1%).Lscs rate was 15.33%.Most of the newborn had weight between 2.5-3.5kg in 68.25% of women in gestational age >40 weeks.
 Conclusions: The present study, we conclude that postdated pregnancy can be considered as a high risk factor from the point of fetal outcome as there is more fetal morbidity.

Summary
Postdated pregnancy is gestation longer than 40 weeks of 280day. Prolonged pregnancy is defined as any pregnancy that last 294 days or more.[1]Terms: 1) Early term: 0/7 weeks through 6/7weeks 2) Full term: 0/7 weeks through 6/7weeks 3) Late term: 0/7 weeks through 6/7week 4) Post term: 0/7 weeks and beyond Indian Perspective It has been widely accepted that factors like race ethnicity affect the duration of pregnancy with Asian and African Americans having a shorter duration.[2]. The presumed etiology for this rise is placental insufficiency Abnormalities such as congenital anomalies, oligohydramnios, meconium aspiration, fetal asphyxia, fetal dysmaturity, macrosomia and shoulder dystocia are commonly observed in these pregnancies Materials and Methods: This study was conducted in the Department of Obstetrics and Gynecology, after approval from the Ethics Committee, from January 2019 to September2020 on 150 patients in the department of Obstetrics and Gynaecology, willing to participate and fulfilling the inclusion and excliusion criteria in the study period.
