Does Vaping Affect Fertility?
Health Guides
If you are trying to conceive or thinking about it in the near future, the question of how vaping affects fertility is worth taking seriously. The evidence draws primarily from research on smoking and nicotine rather than vaping specifically, but the nicotine mechanisms are directly applicable.

The short answer
Does Vaping Affect Fertility?
Current evidence
Yes — nicotine affects both male and female fertility through several mechanisms
Nicotine has measurable effects on reproductive health in both men and women. The evidence comes primarily from research on smoking, which has a longer research history, but the nicotine-specific mechanisms identified are directly relevant to vaping. Vaping does not carry all the reproductive risks associated with smoking — the absence of carbon monoxide and many combustion-related toxins removes some additional concerns. However nicotine itself affects egg quality, ovarian function, sperm quality and sperm DNA integrity in ways that are worth understanding if fertility is a consideration.
This is not medical advice. If you have fertility concerns, please speak to your GP or a fertility specialist. The information here is based on current published evidence about nicotine and reproductive health.
Female fertility
How Nicotine Affects Female Fertility
Nicotine May Accelerate Ovarian Ageing
The ovaries contain a finite supply of eggs (the ovarian reserve) that declines naturally with age. Research on smoking has found that nicotine and related compounds may accelerate this decline, reducing ovarian reserve more rapidly than normal ageing alone. Studies using blood markers of ovarian reserve, including anti-Müllerian hormone (AMH), have found lower values in smokers compared to non-smokers of the same age. While specific vaping studies are limited, nicotine's role in this process suggests the effect may be present in vapers too.
Effect on Egg Quality and Development
Nicotine affects the hormonal environment in which eggs mature. It influences levels of follicle-stimulating hormone (FSH) and luteinising hormone (LH), which regulate the development and release of eggs. Research has found that nicotine can impair the maturation process of oocytes, potentially reducing the proportion of eggs that develop normally. This may affect the likelihood of successful fertilisation and embryo development in women who vape regularly.
Effects on Implantation and Early Pregnancy
Nicotine affects the uterine lining (endometrium) and blood flow to the uterus. Research on smoking has found reduced uterine blood flow and altered endometrial receptivity in nicotine users, which may affect the likelihood of successful embryo implantation. This is a mechanism that applies whether nicotine is delivered through cigarettes, vaping or other NRT products.
Male fertility
How Nicotine Affects Male Fertility
Sperm Count, Motility and Morphology
Multiple studies on smoking have found lower sperm counts, reduced sperm motility (the ability of sperm to swim effectively) and higher rates of abnormal sperm morphology in smokers compared to non-smokers. Nicotine is considered one of the primary agents responsible for these effects, acting through its influence on sperm cell metabolism and the oxidative stress environment in the reproductive tract. Men who vape are likely exposed to these nicotine-related effects, although the absence of combustion products means the overall impact may be less severe than smoking.
Sperm DNA Fragmentation
This is one of the more clinically significant fertility concerns associated with nicotine. DNA fragmentation refers to breaks and damage in the genetic material carried by sperm. High levels of sperm DNA fragmentation are associated with reduced fertilisation rates, lower embryo quality, higher miscarriage rates and poorer outcomes in IVF cycles. Research has found elevated DNA fragmentation in smokers and nicotine users. This is an area where the evidence is strong enough that fertility specialists routinely advise men to stop smoking and nicotine use when trying to conceive.
Nicotine and Testosterone Levels
Nicotine has complex effects on testosterone. Some research suggests it can temporarily raise testosterone through its stimulant effects on the adrenal glands. However chronic nicotine use has been associated in some studies with reduced testosterone production over time, potentially affecting libido and sperm production. This is an area of ongoing research and the picture is not fully settled.
"We always recommend that customers who are trying to conceive, or planning to, speak to their GP about their vaping. Stopping or significantly reducing nicotine before trying is the position most fertility specialists support."

Stop or step down well before trying to conceive
Sperm takes approximately 74 days to mature. Starting to reduce nicotine intake three months before trying to conceive gives the reproductive system time to recover. Women are advised to stop as early as possible before conception attempts.
02
Both partners should address nicotine use
Fertility is a shared concern. Research is clear that male nicotine use affects fertility outcomes including IVF success rates, not just female nicotine use. Both partners reducing or stopping nicotine significantly improves the picture.
03
Speak to your GP
If you are trying to conceive and vaping, discuss it with your GP. They can refer you to appropriate support and may recommend specific testing of fertility markers if you have been trying without success.
