Detailed explanation-1: -It is important to know that, unlike a multiple embryo transfer, twins that result from a single split embryo transfer often cannot be reduced. Because identical twins will most likely share a placenta, it is usually impossible to remove one fetus to give the other the best chance of a healthy birth.
Detailed explanation-2: -Zygotic splitting occurs between days two and six when the zygote divides, usually into two, and each zygote then goes on to develop into an embryo, leading to identical twins (or triplets if it divides into three). These are known as “monozygotic” twins (or triplets).
Detailed explanation-3: -Several factors for causes of embryo splitting were suggested, including maternal age, prolonged embryo culture, ovarian stimulation, and zona pellucida (ZP) manipulation [6].
