They found that this technology reduced the risk of failed embryo transfer and clinical miscarriage. Some background In vitro fertilization (IVF) is an assisted reproductive technology (ART). Eggs...
Read MoreWhat factors influence identical twin pregnancies following ART?
In a nutshell This study investigated factors affecting monozygotic twins (MZT) rates in patients undergoing fertility treatment. They found that embryo stage at transfer and higher embryos numbers increased the risk of MZT. Some background Monozygotic is the term used to describe identical twins. Monozygotic twins (MZT) occur when two embryos form...
