Smoking makes it harder to conceive, irrespective of which partner smokes. Both female and male smokers have lower fertility levels, while adults who were born to mothers who smoked have less chance of becoming a parent themselves. Pregnant women exposed to second-hand smoke are in a great danger of miscarriages and babies with low birth weight. Smoking also reduces the chances of IVF succeeding. It's thought nicotine reduces a woman's fertility by affecting the production of hormones that are necessary for pregnancy. Smoking also impedes the transportation of the egg through the Fallopian tubes to the womb.
