Outcomes in Spontaneous and ART Twin Pregnancies

Maternal and Perinatal Outcomes in Spontaneous Twins Versus Twins Conceived by Ovulation Induction and Assisted Reproductive Techniques: A Cross Section Study Within One Year

During the last decades, assisted reproductive technique has been transformed from a miracle to real and has become widely used for treatment human infertility.

this was associated with increased the rate of twin pregnancies

Twin pregnancies are associated with an increased risk of maternal mortality & morbidity and an increase in the incidence of neonatal morbidity and mortality compared to singleton pregnancy.

The heterogeneous results reported so far can also depend on differences in the studied populations and/or in the management approach to twin pregnancy, variability in data regarding neonatal and maternal outcomes.

Evidence on pregnancy outcomes of twins conceived by artificial reproductive technology (ART) compared with those naturally conceived (NC) is conflicting, A 2004 systematic review and a large 2008 study both were praised that in cases of twin pregnancy after assisted conception the perinatal mortality is significantly lower, when compared with those spontaneously conceived .
