For many couples trying to conceive, fertility is often seen as a female issue — but male fertility plays an equal part. At London Andrology, we regularly see men looking for answers to why conception is taking longer than expected. One of the most common lifestyle factors affecting male fertility is smoking. If you’re a smoker hoping to become a father, quitting might be the most powerful step you can take.
How Smoking Affects Male Fertility
Smoking doesn’t just impact your lungs — it affects almost every system in your body, including your reproductive health. In men, smoking has been linked to lower sperm count, reduced sperm motility (how well the sperm move), and abnormal sperm shape, all of which can make it harder to conceive.
The toxins in cigarettes, including nicotine, cadmium, and lead, cause oxidative stress in the body. This damages sperm DNA, which not only reduces the chances of fertilisation but also increases the risk of miscarriage and health problems in the baby.
Secondhand Smoke Matters Too
Even if your partner doesn’t smoke, secondhand smoke can still impact her fertility and your joint chances of conception. It can affect egg quality and increase the time it takes to fall pregnant. Quitting isn’t just about your health — it’s about giving your future child the best possible start in life.
What Happens When You Quit?
The good news is that the damage caused by smoking can be reversed. Sperm production is ongoing, so positive changes can be seen within a few months of quitting. Studies show that sperm count and motility can improve significantly after just three months without cigarettes.
At London Andrology, we encourage men to take control of their fertility with expert support, testing, and treatment. If you're struggling to conceive and are a smoker, stopping could be the turning point.
Fertility is personal, emotional, and often frustrating — but small changes in lifestyle can make a big difference. Quitting smoking isn’t easy, but it could be one of the most important decisions you make on your path to parenthood.
