This rise continues as the body heals from the damage smoking caused. It can vary by person, but studies find that men who quit smoking see higher testosterone after just one week. Studies show that men who stop smoking see an increase in their testosterone production over time. By using these methods in your lifestyle, you can support healthy hormone production without smoking. Consulting with a healthcare provider can help you develop a plan to quit and address other lifestyle factors that influence hormone health. While quitting smoking can help boost testosterone, it’s also important to focus on other lifestyle factors.
For example, one small 2012 study found conflicting evidence on quitting smoking and testosterone. In addition, men who smoked cigarettes ― but not e-cigarettes ― had significantly higher testosterone levels. But it’s not just cigarettes, gum, or chewing tobacco that appear to affect reproductive changes and testosterone levels. But in a small study from 2022, researchers found that baseball players who chewed nicotine gum had lower levels of salivary testosterone after 30 minutes. While the science isn’t yet clear, you could join the research that’s working to understand how nicotine affects testosterone levels.
Our study assessed the relationship between serum cotinine and total testosterone using weighted linear regression models and subgroup analysis. Therefore, we aim to examine the association between serum cotinine levels and total testosterone concentrations in adult males using data from the U.S. More research is needed to determine the effects of other nicotine replacement methods on testosterone levels. Research on the effects of nicotine replacement methods on testosterone levels is limited. Another meta-analysis of observational studies found that cigarette smoking had a positive and independent effect on testosterone levels. Several research studies have investigated the relationship between smoking and testosterone levels in men. Aside from the impact on hormone levels, there are numerous other benefits to quitting smoking.
NHANES is a cross-sectional survey nationally representative of nutrition and health conditions in the United States, administered by the National Centers for Disease Control (CDC) and the National Center for Health Statistics of Prevention. The data utilized in this study was sourced from the NHANES conducted between 2011 and 2016. The smoking rate among Chinese men is about 47.6%6, while the smoking rate among Russian men is about 60%6. The prevalence of smoking varies by country and region, with higher rates typically found in Asian and European countries. Testosterone is a crucial hormone in male reproductive physiology, playing a vital role in developing and maintaining secondary sexual characteristics and fertility. Serum cotinine is considered a reliable marker of both smoking intensity and exposure to tobacco smoke.

These hormonal imbalances contribute to various health problems like early menopause, menstrual cycle irregularities, diabetes, sleep issues and acne. Many of these chemicals disrupt the endocrine system, leading to hormonal imbalance in both men and women. Cigarette smoke has over 4000 dangerous chemicals that can disturb your body’s normal functioning in various ways. Nicotine withdrawal refers to the physical and emotional symptoms that a person experiences when they stop using nicotine. Although we typically avoid language like this, specificity is key when reporting on research participants and clinical findings. After participants completed a series of physical tests, these low levels returned to their typical levels.
The effects of smoking on testosterone may vary based on personal factors. For this study, researchers suggested that smoking might damage the testicles. Researchers believe this may happen because smoking boosts adrenal gland activity, which can increase testosterone production. For example, one study in the Journal of Clinical Endocrinology and Metabolism found that smokers had higher testosterone than non-smokers. When compared to non-smokers, these smokers had 15% higher total testosterone and 13% higher free testosterone. For decades, smoking has been debated, and many studies link it to various health issues.
Additionally, a 2021 study including 116 postmenopausal women with low zinc levels found that zinc supplementation increased testosterone levels and improved overall sexual function. Our study indicates a potential positive association between smoking and testosterone levels. Conversely, other studies12,27 have indicated that smoking does not have a substantial impact on testosterone levels, while additional studies17,28,29 have shown that smoking may elevate testosterone levels. The research demonstrates a positive association between elevated serum cotinine levels and total testosterone levels in adult males. Beyond the inflection point, total testosterone levels were decreased as serum cotinine increase. In the model 2, which adjusts for age and race, the total testosterone was increased by 0.09 (0.05, 0.13) for each additional unit of serum cotinine. Nevertheless, some studies have also demonstrated a positive association between smoking and elevated testosterone levels14–17.
