Time To Boost IVF Success Rates

In vitro fertilization (IVF) is the go-to option for couples who struggle with infertility or those who want more control over family planning. While the procedure can be life-changing with high success rates, IVF is not foolproof. Some IVF patients still struggle with multiple failed cycles and the inability to conceive. Unlocking higher success rates is possible by diving deeper into the genetic makeup of the embryos used for IVF. Preimplantation genetic diagnosis (PGD) provides more detailed information to help clinics make better decisions, thereby increasing IVF success rates. Understanding the process and when to use PGD can make a big difference on the path to parenthood.

The power of PGD

Preimplantation genetic testing evaluates an embryo's genetic makeup. By taking a biopsy and using strategies like next-generation sequencing, fertility teams can test for hundreds of potential genetic conditions and abnormalities. If 1 or both parents can carry a genetic mutation for single-gene diseases like cystic fibrosis (CF), Huntington's disease, or sickle cell anemia, the condition can be passed down to the baby. PGD lengthens the IVF process but can identify a range of genetic conditions in the embryos, if any are present.

Why is PGD so effective?

Most couples in good health with no known genetic conditions do not need PGD, but men and women with potentially harmful genetic issues may want to opt for the test. PGD analyzes embryos to detect genetic abnormalities, monogenic diseases, and even chromosomal rearrangements. The fertility team can then select embryos free from these genetic mutations to transfer during IVF. By transferring only the healthiest embryos, miscarriage rates decrease, and pregnancy chances improve.

Can PGD increase IVF success rates?

By simply selecting the most genetically healthy embryos, IVF success rates naturally increase compared to selecting embryos with an unknown genetic makeup. Selection criteria expand beyond morphological assessment to ensure only chromosomally normal, mutation-free embryos are transferred. Studies show that using PGD can increase pregnancy rates by selecting embryos with the best genetic viability. This is especially useful for patients at an advanced reproductive age, such as women 40 and older. PGD can even potentially reduce the number of IVF cycles needed to achieve pregnancy.

Accurate diagnosis, pregnancy potential

Preimplantation genetic diagnosis is ideal for individuals or couples at high risk of passing a genetic condition to an offspring. These patients want more control over this outcome, which can be achieved with PGD and IVF. Some couples have specific genetic diseases that are known to cause miscarriages or failed pregnancies. PGD is often recommended in these cases. Women with no known genetic conditions but who still suffer recurrent pregnancy loss can also opt for PGD. Advanced maternal age (AMA), failed IVF attempts, or rare genetic conditions are other reasons to consider PGD. With a diagnosis ahead of transfer, the path to parenthood becomes slightly more straightforward.
