A few weeks ago I wrote about alcohol and testosterone. To continue with the unhealthy habits, I will take on smoking and testosterone in this article and find out what tobacco does to test levels.
I don’t smoke myself and I hadn’t read up on the hormonal effects of tobacco before writing this post.
I was mentally prepared to write about how smoking wrecks the levels of anabolic hormones as booze does to some extent. To my surprise, however, according to studies, this is not the case with tobacco.
In a Czech study, the testosterone levels of 71 men were observed as they quit smoking. Testosterone levels didn’t change for these men when they had ceased their smoking habits. The researchers made a conclusion that smoking tobacco does not have an effect on testosterone levels. 1
But even more surprisingly a Chinese study from 2013 and a previous study from England indicated that smoking tobacco may actually increase testosterone levels in men. 2 3
Nevertheless, smoking tobacco is very unhealthy. And it is not wise to do so even if it might have some positive effects for male hormone levels.
