Does Smoking Tobacco and Cigars Lower Testosterone Levels?
Medical Review by Dr. Stefano Pizzo, MD
For many years I used to think that smoking would completely crush testosterone levels. I didn’t even read the studies about smoking and testosterone, I just assumed that as smoking is so harsh on the human body in so many ways, and the fact that it’s filled with possible endocrine-disrupting chemicals and carcinogenic smoke, that it had to have testosterone lowering effect.
But does it really?
UPDATE 13.4.2015: Added a few studies.
The Science Behind Smoking and Testosterone
I personally don’t smoke, I only tend to do it when I’m drunk.
So smoking and its adverse health effects have never really interested me on a personal level.
But now after this blog is visited by more than 400,000 men on a monthly basis, I have been getting a lot of emails from worried guys asking me if their habit of smoking would decrease their testosterone levels.
So for the first time ever, I decided to take the time to look at the studies about smoking and testosterone.
As you can see from the mounting pile of evidence, it truly seems like smoking doesn’t decrease testosterone levels after all, which is weird. But after such a tremendous amount of evidence from the scientific world, the claim that smoking reduces testosterone levels may just be an empty one.
The research clearly shows that smoking may not decrease human testosterone levels after all. At least that’s what the science says, common sense may differ (mine does for sure).
My recommendation would still be that if you smoke you should give up the habit, as it’s known to cause serious problems with the heart, arteries, lungs, and erections.
…And even though tobacco seemingly doesn’t decrease testosterone, it can still become lethal, which means that you don’t get to enjoy the T in the long run.
