This type of twin formation begins when one sperm fertilizes one egg (oocyte). 1 As the fertilized egg (called a zygote) travels to the uterus, the cells divide and grow into a blastocyst.

Human twin embryos created in the laboratory by splitting single embryos into two using a common method known as blastomere biopsy may be unsuitable both for IVF and for research purposes.

Most IVF twins are born as a result of two embryos being transferred into the uterus at the same time and both implanting. These embryos came from different eggs and are not therefore identical.

"That's a case where we place one embryo back and the embryo itself splits into an identical twin set called the monozygotic set of twins," says Dr. Brahma. Complications with multiple births Dr. Brahma strongly suggests putting back only one embryo into the womb. A single embryo transfer may still result in twins because of embryo "splitting". There is about a 1.6% chance of identical twins arising naturally after a single embryo transfer. (Twins pregnancies can arise because the embryo splits, or also because more than one egg is released during ovulation, resulting in two unrelated pregnancies.). The prevalence of true zygotic splitting was 1.36%, and the researchers found that, compared to singleton pregnancies, using frozen-thawed embryos increased the risk of zygotic splitting embryos by 34%, maturing the blastocysts in the lab for a few days before embryo transfer increased the risk by 79%, and assisted.
