This study aimed at evaluating the pregnancy outcomes of IVF triplets which are spontaneously or electively reduced to twins and to compare them with non-reduced triplets and twins. %26lt;br%26gt;Retrospective analysis of trichorionic triplets and dichorionic twins of IVF pregnancies. %26lt;br%26gt;Preeclampsia rate was significantly higher in triplet group (p = 0.014). Premature contractions requiring tocolysis were seen more often in spontaneous reduction and triplet groups compared to elective reduction and twin groups (p %26lt; 0.001). Elective reduction and twin groups had significantly lower rate of infants weighing less than 1,500 g than those of triplets (p %26lt; 0.001). Highest rate for infants weighing over 2,500 g was found in primary twin group. Preterm delivery rates were significantly lower in both twin and elective reduction groups compared to triplet and spontaneous reduction groups (p %26lt; 0.001). Proportion of women giving birth at term was not different in elective reduction and twin groups, and they were significantly higher compared to spontaneous reduction group (p = 0.024). Perinatal mortality rates of both elective reduction and twin groups were significantly less than those in the triplet group (p = 0.045 and p %26lt; 0.001, respectively). %26lt;br%26gt;Obstetric outcomes of triplets from IVF or ovulation induction cycles undergoing elective reduction are better than ongoing triplet and spontaneous reduction groups and are similar to that of dichorionic twins.
