Egg Quality

What Is Egg Quality?

When women have a failed IVF cycle or are considering undergoing IVF at an advanced maternal age, they are often told that they likely have poor-quality eggs. But what does it mean, and why is egg quality so important for success in infertility treatment? The answer comes down to the simple fact that high-quality eggs produce high-quality embryos: 95 percent of embryo quality comes from the egg. Embryos must be strong enough to survive the early stages of development in order to result in a successful pregnancy, and that’s why egg quality is crucial in the success of fertility treatments.

Why is egg quality important?

Dr. David H. Barad discusses why fertility specialists consider egg quality so important in achieving a successful pregnancy.

As a woman ages, her ovaries’ ability to produce high-quality eggs starts to diminish. This is a condition known as diminished ovarian reserve (DOR) and is the most common cause of infertility for women over 40. Because of their poor egg quality (and resulting poor embryo quality) these women have difficulty conceiving on their own. Success rates of fertility treatments are also lower for these women, who are often refused treatment at fertility centers unless they are willing to use donor eggs. At CHR, however, we specialize in helping women over 40 become pregnant with their own eggs using a treatment plan geared toward improving the number and quality of eggs, taking into account various individual clinical circumstances of our patients with low ovarian reserve.
