Once again, these studies continue to show conflicting results on the impact of nicotine on testosterone. Results of this study found that while androgen levels ― including testosterone ― were already high before quitting, they continued to increase in the year after quitting. During the study, researchers measured hormone levels before the women quit smoking and at 6, 12, 24, and 48 weeks after quitting. Given that SHGB levels decreased in the study after quitting smoking, this may be why testosterone levels fluctuate in some people before and after nicotine use.Ī small 2014 study also explored the impact of quitting smoking on hormone levels in postmenopausal women. SHGB plays an important role in transporting hormones, such as testosterone, around the body. ![]() According to the study results, there was no significant change in testosterone levels in participants after quitting smoking ― but there was a significant decrease in sex hormone-binding globulin (SHBG).

In one study from 2020 on the impact of nicotine on testicular function in men, researchers found that e-cigarette and cigarette users had lower total sperm counts than nonusers. In this study, researchers found that men who used chewing tobacco had a 24% lower sperm count than men who didn’t, but their testosterone levels were, on average, 14% higher.īut it’s not just cigarettes, gum, or chewing tobacco that appear to affect reproductive changes and testosterone levels. After participants completed a series of physical tests, these low levels returned to their typical levels.Ī different 2022 study involving more than 600 Swedish men found conflicting results for oral nicotine use. The review found that while men who smoked appeared to have higher testosterone levels than nonsmokers, there was no significant association between smoking and testosterone changes in women.īut in a small study from 2022, researchers found that baseball players who chewed nicotine gum had lower levels of salivary testosterone after 30 minutes. One 2016 research review explored the effects of nicotine on more than 13,000 men and 6,000 women. In some cases, studies have found that nicotine can increase testosterone levels ― while other studies have found a decrease in testosterone with nicotine use.
