Heavy smoking appears to cut the chances that an embryo will successfully imbed in the wall of the womb, research suggests.
Fertility experts examined pregnancy rates in women who underwent a cycle of IVF using donated eggs.
Researchers from Portugal and Spain, found 52.2% of light smokers became pregnant at the first time of asking, compared to 34.1% of heavy smokers.
They believe that suggests tobacco makes the uterus less receptive.
The study is published online by the journal Human Reproduction.
Lead researcher Dr Sergio Soares said: "The fact that we see this result in a situation in which the oocytes (eggs) were donated by other women demonstrates that cigarette smoking negatively affects the receptiveness of the uterus independently of its effect on ovarian function."
