Evidence-Based Fertility Services in San Diego
The most common reason for embryos to fail implantation or to produce a
healthy pregnancy is that they have an abnormal number of chromosomes.
As many as 30 percent of fertilized human eggs have such abnormalities.
We hope to improve the success rate of IVF by selecting embryos with the
normal number of chromosomes to transfer into the uterus.
Traditionally in IVF procedures, doctors and embryologists visually inspect
embryos and then decide to transfer those that appear morphologically
healthy after 5-6 days of development. Many IVF centers transfer more
than one embryo at a time, because many of them won’t result in
a successful pregnancy. However, if multiple embryos do implant successfully
it can be risky for both the mother and the fetus.
To reduce such risks, we only transfer a single embryo at a time, and new
genetic screening technologies are helping us ensure that we select the
most viable and healthy one.
