title: Outcome of twin pregnancies after assisted reproductive techniques--a comparative study.
abstract: OBJECTIVE
  To compare obstetrical and perinatal outcome of twin pregnancies after assisted reproductive techniques (ART) with that of twins conceived spontaneously.
  
  
  METHODS
  Hospital based retrospective study.
  
  
  RESULTS
  There were 132 twin deliveries of which 36 were conceived after ART. Patients of the ART group were mostly nulliparous and slightly older. There was no statistically significant difference in the frequency of preterm delivery or mean gestational age at delivery. Elective Caesarean delivery was more frequent in twin pregnancies conceived after ART, and there were no other differences in maternal complications. There was also no difference in the mean birth weight or frequency of neonatal complication between the two groups.
  
  
  CONCLUSIONS
  In this comparative study, the obstetric and neonatal outcomes between spontaneous twins and those conceived after ART are similar except for higher operative deliveries in the latter group of twins.
