The odds of having a baby via in-vitro fertilisation (IVF) may be lower for obese women than their thinner counterparts, two new studies find. The studies, reported in the journal Fertility and Sterility, add to evidence suggesting that heavy women have a lesser chance of success with IVF.
In the other study, the odds of success were lower only for obese women, and not those who were less overweight. Of 477 women who were moderately obese, 22% had a baby. That compared with 30% of normal-weight women.
