Does Nicotine Increase Testosterone?

Nicotine and testosterone are topics that get a lot of attention online, especially in fitness and performance conversations. Some posts suggest nicotine may raise testosterone, while others warn it could affect hormones over time. So what does the research actually say?

The short answer: there is no clear evidence that nicotine increases testosterone in a meaningful or beneficial way. Some studies of cigarette smokers have found higher average testosterone levels than those of non-smokers, but that does not prove nicotine caused the difference. And because most research looks at smoking (not nicotine pouches), these findings should not be used to claim that nicotine pouches raise testosterone or improve performance. 

Testosterone is a hormone that helps the body with several normal functions, including reproductive health, muscle maintenance, bone health, and red blood cell production. Testosterone levels can change for many reasons, including age, sleep, time of day, medications, health conditions, and lifestyle. Because levels naturally go up and down, it is not accurate to assume that one product or habit will meaningfully change testosterone without strong evidence. 

The research is mixed, and most of it does not look at nicotine pouches. A systematic review and meta-analysis found that men who smoked cigarettes had higher average testosterone levels than men who did not smoke. But this type of research can only show a link. It cannot prove that smoking, nicotine, or any nicotine product caused testosterone levels to rise.

A population-based study from Norway also found higher total and free testosterone levels among men who smoked compared with men who never smoked. The researchers noted that smoking may complicate how testosterone results are interpreted. This finding does not mean smoking, nicotine, or nicotine pouches should be used to influence hormone levels.

More recent research using serum cotinine, a marker of nicotine exposure, found a link between cotinine and total testosterone in adult men in the U.S. However, the relationship was not simple and may change at very high exposure levels. Overall, the evidence does not support a simple claim that nicotine “boosts” testosterone. 

Most studies on nicotine and testosterone are really studies about cigarette smoking. That matters because cigarette smoke contains many substances besides nicotine, and smoking has well-known health risks. If smokers and non-smokers have different testosterone levels, researchers cannot easily tell whether that difference is related to nicotine, smoke exposure, lifestyle factors, or something else.

Nicotine pouches are different from cigarettes, but there is not enough direct research to say that they increase, decrease, or meaningfully affect testosterone levels. That means the most accurate answer is still: we do not know enough to make a claim either way.
