Obese women undergoing in vitro fertilisation (IVF) may be half as likely as their normal-weight counterparts to have a baby, a study at one US medical centre suggests.
It's known that obesity can affect a woman's ability to conceive naturally. However, "there is still a fair amount of uncertainty and debate as to how obesity affects IVF outcome," said Dr Divya K. Shah, the lead researcher on the new study.
IVF and obesity
IVF involves fertilising a woman's eggs - either the patient's own or eggs from a donor - in a lab dish, then implanting any resulting embryos in the patient's uterus a few days later.
