Twins with IVF Treatment

One of the biggest reasons for multiple pregnancies is that the embryos are transferred into the uterus at once. Embryos are implanted within a period of 6-12 days, and then implantation should occur. But sometimes, the embryo does not invest in the uterus. This is called a failed pregnancy. Then the couple needs to try again.

Due to the high cost of IVF treatment, most couples cannot afford more than one cycle. Usually, 2 or 3 embryos are transferred to the uterus at a time during the IVF procedure. One reason for this is that it's hoped that at least one embryo will successfully attach itself to the uterine lining and grow into a foetus.

If there's not much problem with the uterus, the chance of pregnancy is relatively high. Hence, if many embryos have been placed in the uterus, their survival chances are relatively high. Therefore, many women who have undergone IVF become pregnant with twins.
