A new study casts doubt on the genetic test that eliminates a majority of potential embryos from use in vitro fertilization due to possible abnormalities.
The selection process limits the success of IVF, especially among older women and those diagnosed with premature ovarian aging.
As reported in
Nature Cell Biology, researchers found that embryos often develop into healthy babies regardless of whether or not they’ve been blacklisted by the test, and have demonstrated how supposedly defective embryos self-correct during gestation.
“This is going to revolutionize how IVF moves forward,” says Ali H. Brivanlou, head of the Laboratory of Synthetic Embryology at Rockefeller University. “This test is obsolete and should be replaced with more precise technology to assess in vitro-fertilized embryo quality.”
