Smoking and fertility

You know that smoking is bad for you, but you may not know about the negative effects smoking has on your chances of becoming a parent and having a healthy baby.

Smokers take longer to conceive than non-smokers and are more likely to have fertility issues

Men and women who smoke – and women who are exposed to other people’s smoke – are more likely to take longer to get pregnant, while both active smoking and passive smoking (inhaling someone else’s smoke) increases a woman’s risk of infertility. In fact, passive smoking is only slightly less harmful to a woman’s fertility than active smoking.

Pregnant women who smoke can find it more difficult to quit if they have a partner who smokes. Research shows it is much easier for people to stop smoking if they do it with their partner. Deciding to quit together is a great way to increase your fertility and chances of having a healthy baby.

The facts about smoking and having a baby

  • Smoking can cause erectile dysfunction.
  • Smoking in the three months before conception can damage the DNA in sperm, affecting the health of a child.
  • Exposure to cigarette smoking during pregnancy can impact on the development of a female foetus’ ovaries.
  • Smoking by the father or both parents around the time of conception is a risk factor for childhood leukaemia.
  • Women who are exposed to second-hand smoke reach menopause more than a year earlier than non-smokers.

The good news?

  • Sperm takes three months to develop which means that the most important time for men to improve their health and quit smoking is in the three months leading up to conception.
  • Stopping smoking can improve natural fertility and some of the effects of smoking can be reversed within a year of quitting.
