(KAIT/NBC) - Researchers are taking a close look at the long-term safety of in vitro fertilization.
There may be links between IVF and certain birth defects.
Two studies suggest larger than normal babies and congenital heart defects may be linked to IVF.
More patients are questioning their options after a storage tank malfunction in Cleveland, Ohio back in March.
Doctor Lowell Ku, Medical Director at Dallas IVF, says this is still the most successful form of assisted reproductive technology.
"Luckily we have a lot of mechanisms in place that will protect both the embryos, their future and a healthy baby," said Dr. Ku. "Our goal is definitely is a healthy baby and we will help them with that."
Dr. Ku adds that storage tank failures are rare--facilities always inspect their policies to make sure they are as fool-proof as possible.
Genetic screening of embryos also helps prevent birth defects.
