Key things to know
- Quitting smoking or vaping improves fertility and pregnancy health.
- Nicotine, whether in cigarettes, or e-cigarettes, can affect your baby’s development.
- Chemicals in vapes may cause DNA damage, which can put your future baby’s health at risk.
- Both partners can play a positive role by supporting each other to quit before the baby bump.
Before the baby bump describes the time before you are pregnant, when you might be thinking about having a baby, or starting to try for one. It is called preconception.
Quitting smoking and avoiding e-cigarettes (vapes) supports healthier eggs and sperm, a stronger pregnancy, and improved long-term outcomes for both parents and children.
Making the decision to stop smoking or vaping is one of the most powerful steps you can take to improve your fertility and give your future baby the best possible start.
Quitting smoking before the bump can significantly reduce the risk of miscarriage. Research shows the risk increases by about 1% for every cigarette smoked per day (Pineles, et al., 2014).
Based on the Quit and Your Fertility interactive tool, each month without smoking or vaping has a positive effect on your health and your future child.
| 1 month | 2 months | 3 months | 4 months | 6 months | |
|---|---|---|---|---|---|
| Females | As soon as you stop smoking, your fertility begins to improve. Your body is better at fighting infection. |
Your lungs are starting to heal as cilia, the tiny hairs that clean your lungs, begin to recover from paralysing tobacco toxins. You are coughing and wheezing less. |
You have now reduced the risk of your baby being born prematurely to the same level of risk for non-smokers. | Your blood is less thick and sticky, reducing your risk of harmful clots. | Your stress levels have lowered to ‘non-smoking’ levels. |
| Males | It’s never too late to quit. No matter how long you’ve smoked, stopping now will start to improve your sperm health. | Your lungs are repairing. Your lung function is improving, making it easier to clear mucus and reducing your risk of infection. | Sperm take 3 months to develop, so you now have smoke free, healthy sperm. | Your lung function has improved significantly, reducing coughing and shortness of breath. | Your stress levels have lowered to ‘non-smoking’ levels. |
Myth busting
Stopping smoking improves your health, boosts fertility, and lowers the risk of pregnancy complications such as miscarriage, ectopic pregnancy, still birth and premature labour.
Ideally both men and women should stop smoking 4 months before trying for a baby, but stopping any time can help.
Reducing the number of cigarettes or frequency of vaping is a positive step towards health, but even low levels of smoking can make falling pregnant more difficult.
E-cigarettes, or vapes, may help some people quit smoking but their safety before and during pregnancy is not yet known. Proven safer options include Nicotine Replacement Therapy (NRT) and support from trained services.

Wait! There’s more
More Money
In 2025, the average cost of a 20-pack of cigarettes in Australia is $45, with the average Australian smoker spending approximately $36 each day*. Vaping is not as expensive
1 week = $252 saved
1 month = $1,080 saved
6 months = $6,480 saved
1 year = $13,140 saved
That’s not just money saved from not buying cigarettes – you will also likely spend less on healthcare, insurance premiums, and dental costs.
*Based on 16 cigarettes a day average
More Energy
Smoking can affect your lungs, sleep, and blood circulation. Quitting smoking improves lung function, boosts energy, helps you sleep better, and supports healthier circulation.
More Zen
Smoking and vaping are often used to reduce stress, but research shows they actually increase anxiety and tension. Quitting smoking won’t remove stress, but it can help you handle it more effectively.
Better Immunity
Smoking and vaping reduce your ability to fight infections. Quitting can reduce the number of times you get sick, and help you recover faster.
Work as a team
Couples who quit smoking or vaping together are more likely to stay smoke-free. They are also more likely to conceive naturally and sooner than couples who continue smoking or vaping.
Passive smoking or vaping can also affect pregnancy. Exposure to second-hand smoke increases the risk of miscarriage and stillbirth, and indoor vaping releases tiny chemical particles that can be harmful to breathe.
If your partner is not ready to quit, ask them not to smoke or vape near you when you start trying for a baby.
