A Defense of PGS

An article recently published in The Cut column of New York Magazine has captured the attention of the fertility and genetic testing community. Titled “A New Last Chance”, the article questioned the utility of preimplantation genetic screening (PGS) – a technique which data from the CDC and SART, along with the results of several randomized controlled trials (RCTs), have all …

How many embryos to transfer in IVF?

When we first started doing IVF in the 1980’s the state of the science, like culture techniques and only being able to sustain embryos in the lab until Day 2 or 3, required us to transfer multiple embryos to have any decent chance of success. One of the big problems we faced was the risk of high order multiple pregnancies. …

Making IVF More Successful. What works?

A recent article in Newsweek looks at “add-ons” to the basic IVF cycle and comes to the conclusion that there is no evidence that many of them help except the endometrial “scratch”: biopsy in the cycle before the transfer.

These add-ons include blastocyst culture, where the embryo is allowed to grow in the lab for five days instead of the …

Egg freezing does not increase chance of chromosome abnormalities

A reassuring study in the October 2010 issue of Fertility & Sterility demonstrates that blastocysts created from previously vitrified eggs are not at risk for an increased risk of abnormal chromosome configuration (aneuploidy) and have equivalent reproductive potential to those created from fresh eggs.

To assess the risk they froze half of the eggs by vitrification and compared the results …
