Why is the risk of birth defects higher for women using ART?

New research suggests teratogenic medications may be to blame.

Greater use of teratogenic drugs might explain the established higher risk of birth defects in pregnancies conceived through assisted reproductive technology, study findings suggest.

Australian researchers have shown that higher exposure to teratogens in assisted reproductive technology (ART) and ovulation induction (OI) pregnancies is likely due to medications, not chronic conditions.
