Does Vaping Affect Fertility?

Smoking clearly harms fertility; vaping is less researched and not assumed safe. When trying to conceive, the advice is to avoid nicotine.

If you are thinking about starting a family, it is wise to ask whether vaping affects fertility. The honest position is that smoking is clearly harmful to fertility in both men and women, while vaping is newer and less researched, so it cannot be assumed to be free of effects on fertility. Because nicotine and other ingredients may have an impact, the advice when trying to conceive is to avoid smoking and ideally nicotine altogether. This guide explains what is known.

Quick answer

Smoking clearly harms fertility in both men and women. Vaping is less researched, so it cannot be assumed safe for fertility, and nicotine may have effects. If you are trying to conceive, the advice is to avoid smoking and ideally nicotine altogether, and to speak to a GP.

What we know about smoking and fertility

The clearest evidence is about smoking, which is well established as harmful to fertility for both partners. It can affect the chances of conceiving and is linked to a range of reproductive problems. Stopping smoking is one of the recommended steps for couples trying to conceive, which is why it features in fertility advice so prominently.

Where vaping fits

Vaping is much newer than smoking, so the long term research on its effect on fertility is still developing and less complete. What we can say is that it is far less harmful than smoking in general, but that does not mean it is proven safe for fertility, and nicotine itself may play a role. The responsible position is caution rather than reassurance, especially when actively trying for a baby.

Smoking clearly harms fertility, and vaping is too new to be called safe for it. When trying to conceive, the cautious, sensible step is to avoid nicotine altogether.

Looking after fertility as a couple

Fertility is very much a shared matter, so when a couple is trying to conceive, both partners looking after their health gives the best chance. Stopping smoking is one of the clearest, evidence based steps, and avoiding nicotine altogether is the cautious extension of that while the research on vaping continues to develop. Other lifestyle factors, like a balanced diet, healthy weight and limiting alcohol, matter too.

If conceiving is proving difficult, a GP is the right first port of call. They can offer advice, checks and, where needed, referral, and they will often raise smoking and nicotine as part of that conversation, so tackling it early is worthwhile.

A quick word on safety and the law

Vaping products are intended for adult smokers and existing vapers as a less harmful alternative to cigarettes. They contain nicotine unless stated otherwise, which is addictive, and they are not suitable for non smokers, pregnant women or anyone under 18. By law you must be 18 or over to buy vaping products in the UK, and we age verify every order. If you want to stop using nicotine altogether, your local stop smoking service offers free, tailored support.

UK public health bodies advise that vaping is substantially less harmful than smoking, but it is not risk free, and if you do not smoke the advice is not to start.
