Comparison of twin pregnancy outcome after assisted reproductive technology with and without embryo reduction

Background: spontaneous occurrences of multifetal pregnancies always have been a medical problem.the risks of perinatal morbidity and mortality and maternal morbidity increase with enhancement of thenumber of fetuses.in our prospective experimental study, the outcome of twin pregnancy after assisted reproductivetechnologies (art) with and without multifetal pregnancy reduction (mfpr) is compared relating toperinatal and maternal complications.objective: the aim of this study was to compare the gestational age at delivery, birth weight, and othercomplications of surviving twins following mfpr to those in a control group of non-reduced twins.materials and methods: in this prospective experimental study, from infertile couples whowere referredto isfahan fertility- infertility center (ific) and were candidate for art (invitro fertilization or intracytoplasmic sperm injection), 30 couples who have had twin (control group) and 35 couples with quadruplet orhigher order pregnancies (experimental group) were selected. in cases withexperimental group mfprwas done,andpregnancy outcome-miscarriage, premature labor, premature preterm rupture of membranes (pprom)and pregnancy induced hypertension (pih)-were compared between two groups.results: distribution of complications in experimental vs. control groups wasas follows: miscarriage: 23.3vs. 16 .7%, premature labor: 15.7% vs. 13.3 %, pregnancy induced hypertension: 13.3% vs. 16.7%,abruption: 6.7%vs. 6.7%, and premature preterm rupture of membranes: 23.3% vs. 26.7%. mean neonatalweight at birth (2239 vs. 2240 gr) and mean gestational age at delivery (33.5 vs. 34.1 w) weresimilar. thedifferences between two groups werenot statistically significant (p>0.05).conclusion: mfpr during early pregnancy is a safe, effective and simple operative for the purpose ofreducing perinatal and maternal complications.
