Generally selective reduction reduces the risk of preterm birth, leading to better outcomes for both mothers and the newborns.<ref name=Obican2015>{{cite journal |last1=Običan |first1=S |last2=Brock |first2=C |last3=Berkowitz |first3=R |last4=Wapner |first4=RJ |title=Multifetal Pregnancy Reduction. |journal=Clinical Obstetrics and Gynecology |date=September 2015 |volume=58 |issue=3 |pages=574–84 |doi=10.1097/GRF.0000000000000119 |pmid=26083128|s2cid=10307261 }}</ref>

It appears that reduction of triplets, where each triplet is in its own placenta, to twins results in a lower risk of preterm birth and does not increase the risk of miscarriage. In triplets where two of the fetuses share a placenta and each has its own amniotic sac, it appears, with less certainty, that there is also a lower risk of preterm birth and no increase in the risk of miscarriage.<ref name=":0">{{cite journal |last1=Anthoulakis |first1=C |last2=Dagklis |first2=T |last3=Mamopoulos |first3=A |last4=Athanasiadis |first4=A |title=Risks of miscarriage or preterm delivery in trichorionic and dichorionic triplet pregnancies with embryo reduction versus expectant management: a systematic review and meta-analysis. |journal=Human Reproduction (Oxford, England) |date=1 June 2017 |volume=32 |issue=6 |pages=1351–1359 |doi=10.1093/humrep/dex084 |pmid=28444191|s2cid=3778609 |doi-access=free }}</ref>
