Most multiple pregnancies after IVF treatment are result of implantation of more than one embryo (“fraternal twins”). Therefore, the risk of a multiple pregnancy increases with the number of embryos that are transferred. Multiple pregnancies are linked with an elevated risk of numerous complications of pregnancy including miscarriage, toxemia, hereditary anomalies, gestational diabetes, and premature birth. Indeed, the most concerning risk of a multiple pregnancy is prematurity. Babies born from triplet pregnancies have a 20% chance of a significant handicap, a 17-fold increase in cerebral palsy, along with a 20-fold increase in death throughout the first year after birth (as compared to a singleton pregnancy).
Monozygotic twins (MZT) is a multiple pregnancy that is resulted of the splitting of a single embryo, which can result in some identical twins. The incidence of MZT is elevated in pregnancies conceived after IVF. MZT pregnancies tend to be more complicated due to the perils of twin-to-twin transfusion and twine accidents. A multiple pregnancy might also pose elevated emotional and financial difficulty for a couple. If multiple pregnancy develops, the couple may think about a multi-fetal reduction procedure. This procedure, that is performed in the first trimester of pregnancy, reduces the number of fetuses to a lower and
safer number. Even though the high rate of success, a miscarriage may result from the procedure.
Using the ongoing improvement in outcomes, transferring a two embryos has become the most well-liked method for most patients.
