This rate of attrition is normal and is a result of the poor developmental potential of some of the embryos..
Why does IVF fail the first time?
One of the most common reasons as to why an IVF cycle fails is due to the quality of the embryo. Many embryos are unable to implant after transfer to the uterus as they are defective. Embryos that look healthy in a lab may have defects that cause them to die rather than grow.

Too many women give up on in vitro fertilization too soon, a new study suggests.

What percentage of fertilized eggs make it full?
Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus. In nature, 50 percent of all fertilized eggs are lost before a woman’s missed menses.
Why is IVF bad?
