The Best Egg for the Job
One of the most amazing breakthroughs comes in the form of testing the female egg before it is used in IVF. According to Dr. Scott Whitten, a fertility specialist with the Nevada Center for Reproductive Medicine, preimplantation genetic diagnosis (PGD) is a technique that can be performed during an IVF cycle to identify embryos that may be affected with a genetic or chromosomal abnormality.

"PGD was originally designed to assist couples with single gene disorders (e.g. cystic fibrosis) to avoid transferring embryos that carried a known mutation of the mother and/or father," Dr. Whitten says. "There are now over 100 genetic disorders that can be identified with this technique.

Dr. Geoffrey Sher, who along with Levent Keskintepe, Ph.D., both of ReproCure LLC and the Sher Institutes for Reproductive MedicineSM, have developed a process that by completely analyzing the chromosomal make-up of the human egg and embryo, allows identification of that embryo that will develop into a healthy baby. Using a method known as Comparative Genomic Hybridization (CGH) to identify chromosomally normal eggs allows researchers to identify "competent" eggs, which are then fertilized and allowed to develop into embryos.
