PGD and Frozen Embryo Transfers yield higher pregnancy rates than fresh embryos! What is FET? What is PGD? “The problems with IVF are pretty well known: pregnancy rates are not as good as they should be".
In vitro fertilization (IVF) is a type of assisted reproduction technology (ART) in which a woman’s egg (or a donated egg) is fertilized in a laboratory with her partner’s sperm or donated sperm. The resulting embryo is then transferred to the uterus to develop naturally.
A recently published study evaluated blastocyst transfer outcomes for women age 40 to 44, according to the number and quality of embryos transferred in their IVF cycle. “The question we wanted to ask from a research standpoint is, ‘Where do you draw the line between maximizing the chance of a healthy pregnancy and increasing the risk of a multiple pregnancy as women age?’” says Dr. Eric Widra, Medical Director of Shady Grove Fertility. “Do the same rules apply as women get older?”
A recently published study demonstrated that banking zygotes (one-cell, fertilized embryos) for comprehensive chromosomal screening (CCS) helps achieve ongoing clinical pregnancy in women with diminished ovarian reserve who have had previous IVF failure.
It is known that ovarian age plays a role in embryo implantation failure and miscarriage. But does the chronological age of the uterus also affect implantation rates? A study by Reproductive Medicine Associates of New York (RMA of NY) has demonstrated that, no, uterine aging does not contribute to the age-related decline in fertility. Implantation rates will not be affected by the chronological age of the uterus.

In a recently published study, “Patient Treatment Journeys, Then and Now: 12 Years of Clinical Progress”, RMA of NY analyzed 12 years of data from diagnostic cycles, IVF cycles, egg recipient cycles and non-IVF cycles to identify the trends and progress achieved. The study showed that the time span from patients’ first consultation to discharge to their obstetrician had decreased from 9.1 months to 5.7 months. Additionally, patients experienced a significant reduction in the number of multiple gestations (which decreased by 50% over that time period), and a diminished number of miscarriages due to the increased utilization of embryo screening technologies.
What is the Two Week Wait (2WW)? Following infertility treatment, there’s the inevitable two-week wait before taking a pregnancy test. If the treatment was successful, your body will already be going through changes, some noticeable, others imperceptible. What’s happening inside the uterus is impossible to literally feel, but can set off all sorts of palpable symptoms, both emotional and physical.
Frozen embryos are a large part of fertility treatment. Having stored embryos can allow a couple to preserve their fertility or can provide a way to continue fertility treatment without the need for additional egg retrievals. What many couples don’t think about is what to do with frozen embryos should they not be needed in the future. There are a number of options available to couples, including embryo disposal. The right way to take care of your embryos is a personal decision, with no “right” answer.
