Frozen embryos help lower risk of defects

In a study which also confirmed that intracytoplasmic sperm injection (ICSI) carries a higher risk of birth defects compared to in vitro fertilisation (IVF), researchers at the Robinson Institute, University of Adelaide, analysed data on nearly 309,000 births including 6100 births from ART.

Co-author Professor Eric Haan said when comparing fresh IVF and ICSI, IVF was 36% less likely to result in birth defects than ICSI.

“However, when the embryos were frozen the risks of birth defects in both procedures decreased significantly,” he said.

The researchers found an overall 8.3% risk of &nbsp
