Exploring the Chances and Considerations of Having Twins Through IVF
Understanding IVF and Twins
IVF can result in identical or fraternal twins. Identical twins come from a single embryo that splits, sharing the same DNA and sex. Fraternal twins occur when two embryos are transferred and implant separately, resulting in different DNA and possibly different sexes.
Chances of Having Twins with IVF
Technological advancements have reduced the likelihood of twins from IVF. In 2011, the twin rate was 8.4%, dropping to 2.3% in 2020 due to the increased practice of single embryo transfers (eSET). Transferring one embryo results in a 0.1-2% chance of twins, while transferring two or more embryos raises the likelihood to 12-30%.
Considering IVF for Twins
Many couples desire twins to avoid multiple IVF cycles. Financial considerations often influence the decision to transfer multiple embryos. IVF costs vary, with the American Society for Reproductive Medicine (ASRM) noting an average cycle cost of $19,200, whereas some clinics offer more affordable options.
Risks of Twin Pregnancies
Twin pregnancies carry higher risks, including high blood pressure, gestational diabetes, premature labor, and increased likelihood of cesarean sections and postpartum hemorrhage.
Managing Twin Pregnancy Risks
Discuss embryo transfer options with your fertility provider, considering the ASRM's recommendation for single embryo transfers. Understanding risks and financial implications can guide your decision.
