Heavy Smoking Cuts Women's Chance Of Pregnancy -- Even With Donated Eggs -Another Reason to Quit Smoking With Hypnosis

Heavy smoking may reduce female fertility by directly affecting the uterus ( by making it less receptive and reducing the chances the embryo will implant) according to research published online (Thursday 9 November) in Europe's leading reproductive medicine journal Human Reproduction.

This suggestion comes as a result of comparing the pregnancy rates between non-heavy smokers and heavy smokers, all of whom received donated eggs.

This study is the first to examine the impact of smoking in women who have received donated eggs. This allows for a objective assessment of the role of the uterus in the outcome of IVF.

The researchers studied all the first cycles of egg-donated IVF treatments 741 in non-heavy smokers (under 10 cigarettes a day) and 44 in heavy smokers (over 10 a day). None of the women's partners were smokers and none of the egg donors were heavy smokers. The two groups of recipients were comparable and the number of embryos transferred in each cycle (between one and three) was also comparable between the groups.

Lead researcher Dr Sérgio Soares, said: "The non-heavy smokers had a significantly higher pregnancy rate, with over half becoming pregnant (52.2%), compared with just over a third (34.1%) of the heavy smokers. This means we have confirmed previous data that show light smoking has no significant impact on IVF cycles, either through affecting the egg or the uterus. However, heavy smokers have a much lower chance of achieving pregnancy. The fact that we see this result in a situation in which the egss were donated by other women demonstrates that cigarette smoking negatively affects the receptiveness of the uterus independently of its effect on ovarian function, and this is a new finding....The clinical implications of the findings were clear. Tobacco makes the uterus less likely to accept an embryo."

We should now let our clients know, if they are heavy smokers, that even if fertilisation takes place they have less chance of achieving a successful pregnancy, whether they are trying to conceive naturally, or through IVF, and particularly with donated eggs.
