Effects of smoking on fertility
For women who smoke, their chances of conceiving are reduced. On average it takes an extra two months to get pregnant if a woman smokes, compared to a non-smoker. However, women who quit smoking a year before attempting to conceive are likely to get pregnant within a similar time period as non-smokers.
It is never too late to give up; a year after quitting, a woman’s chances of conceiving return to that of a woman who has never smoked.
Men who smoke can have low testosterone levels, low sperm count and sperm deformities. Smoking can also cause impotence i.e. the inability to have an erection.
