Cause of twinsin SET is zygote splitting-Zygote is formed after fertilization of ovum with sperm which further develops in an embryo. Due to zygotic splitting phenomenon instead of one ,two embryos develop as seen in above picture resulting in twin pregnancy.This occurs rarely in spontaneous conce...
The present invention relates to a method for producing homozygous twins by means of embryo splitting without the use of micro-manipulators. The embryos used were in the morula stage and were manually divided with a micro-knife in a fixation/manipulation medium. Following division, the embryos ...

splitting the batch among said couples for $9800 plus expenses. I kept asking Corey (the IVF coordinator) prior to my consult, who the original parents were. I could never get an answer from him. Dr Z. didn’t come right out and say it, but clearly there are NO original parents. I...
and embryo bisection further improve the utility of this technique. Embryo bisection or splitting results in the production of identical twins from a single embryo. Nuclear transfer or cloning techniques are an extension to embryo transfer procedures. Cloning is based on the removal of DNA from the...
Additionally, a clone embryo may arise by the splitting of an embryo (e.g. the formation of monozygotic twins). If a cloned embryo arises from a cloning procedure that includes at least one re-cloning step, then the cloned embryo can indirectly arise from a totipotent cell since the re-...
