متن کاملThe precise timing of embryo splitting for monozygotic dichorionic diamniotic twins: when does embryo splitting for monozygotic dichorionic diamniotic twins occur? Evidence for splitting at the morula/blastocyst stage from studies of in vitro fertilization.

We report the delivery of healthy monozygous (MZ) twins in a 31 year-old nulligravida following gonadotrophin ovulation induction, ICSI, assisted hatching and fresh embryo transfer. Although a sonogram on day 35 confirmed that two of four transferred embryos had implanted, a second transvaginal sonogram 1 week later showed each gestational sac had two conceptuses-all four were associated with d...
