Does Smoking Shrink the Penis?

Man smoking a cigarette

You’ve been told forever that smoking is bad for your heart and lungs, for your teeth, and probably for your skin. 

But lately you’ve been hearing alarming things about it being bad for your penis. 

Can it be true? Can smoking actually make your penis smaller?

The short answer is yes. Kind of. In a roundabout way. And maybe also directly. 

Here’s the long answer. 

Smoking is Really, Really Bad For You

It’s likely you’ve heard this before, but if you’re reading this article you might need a reminder. Or you’re finally ready to listen now that we’re talking about something that really matters.

Here’s a partial list of the stuff that can go wrong with your body if you’re a habitual smoker, according to the Centers for Disease Control:

  • Lung cancer
  • Coronary heart disease
  • Stroke
  • Damaged blood vessels
  • Emphysema
  • COPD
  • Reduced bone health
  • Tooth decay and gum disease
  • Rheumatoid arthritis
  • Cataracts

Smoking also increases your risk of all kinds of non-lung cancers, including cancers of the bladder, colon, rectum, esophagus, kidney, larynx, liver, pancreas, stomach, and trachea.

It’s seriously bad news for your general health. Poor general health can lead to penile shrinkage in two ways. 

First, it accelerates the impact of aging… 

Age-related testosterone loss causes hypogonadism (shrinking of the testes and penis). Fortunately, you can do things to counteract it. 

Smoking does the opposite, actually making that shrinking come on faster. 

Second, it reduces erectile quality because of its negative impact on your general health.

If your boners aren’t as strong as possible, they’re not as long as possible. That means a smaller penis when it matters most. 

Beyond these general issues on the size of your member, smoking also makes some direct attacks against your worth and girth.

Smoking Shrinks Penis Size During Erections

Smoking does its worst damage against your lungs, throat, mouth, and other parts of your body it touches directly. 

That’s why the American Lung Association leads one of the most aggressive anti-smoking campaigns you’ll ever find. 

It does its second worst damage against your circulatory system. 

It damages your heart, leads to constriction of and damage to your blood vessels, and increases your risk for problems with blood pressure and blood flow. 

As you might remember from health class, you get erections because your penis floods with blood. That’s what makes it hard (think of a water balloon filling up). 

If your circulatory system is all messed up because of your smoking, it can cut that blood flow to an unreliable trickle (think of filling a water balloon with a squirt gun). 

That doesn’t necessarily mean you won’t be able to get it up at all if you keep smoking. It does mean you’re likely to experience weaker erections with each passing year. 

Weaker erections are smaller erections, like I suggested earlier. 

But don’t just take my word for it. A 2005 study published in the American Journal of Epidemiology found that men who smoked were more likely to suffer from full erectile dysfunction — almost twice as likely, in fact (source).  

The study didn’t look at what caused the correlation. Neither did the multiple other studies that found the same results. That’s because the mechanics of it are pretty well understood. 

And, as we saw further up in this article, weak erections make your penis seem smaller at the worst possible time. Even if smoking doesn’t cause outright no-boner erectile dysfunction, it will soften and shrink your package when it’s, um…time to deliver. 

Smoking Damages Testicular Health

Hurting your testicles accelerates that age-related shrinkage I mentioned earlier, because it harms the organs that make your testosterone. 

One of the early warning signs that your testicles are in trouble is declining health of your sperm. A stack of studies have demonstrated smoking is bad for your little swimmers. 

A few examples:

  • A 1999 study in Bath, UK found it caused mutation within the DNA carried by a smoker’s sperm at a rate of 150% that of nonsmokers.
  • Mexico: 2009. A university study found smokers had lower sperm density, viability, and motility, and higher occurrence of misshapen sperm than non-smokers (source).
  • A Bulgarian study in 2004 found that smokers produced sperm with damaged cell membranes in significantly higher quantity than nonsmokers of the same approximate age. 

Those damaged sperm mean damaged and unproductive testicles. Damaged testicles mean less testosterone. Less testosterone = smaller gonads.

Penis size can also be impacted by psychology. This is mostly another aspect of erection quality, but some conditions like depression can also reduce testosterone, leading to direct penis shrinkage. 

As it turns out, this interacts negatively with smoking in a number of ways:

  • Smoking can reduce libido
  • Reduced cardiovascular health can impact sexual performance
  • Smoking is linked with depression — it can be a symptom or a cause
  • If your partner doesn’t smoke, fighting about smoking can impact your sex life
  • The nicotine “buzz” constricts blood flow, which can immediately reduce erectile quality
  • Second-hand smoke can impact your partner’s health, including her sexual health

There are just so many ways smoking can mess with your penis. 

Many health officials prefer not to mention this. They want to tell you about how you’ll die young hooked up to a CPAP machine…but we know what’s really important to you. 

Your pecker.

Does Smoking Shrink the Penis- Conclusion:

One way smoking will absolutely shrink your penis: it’s probably going to kill you. 

Once rigor mortis fades, you’ll be stuck with your flaccid size for the rest of eternity…at least as much of eternity as your body sticks around.

But all (partial) kidding aside, smoking is bad for your whole body. Since your whole body includes your penis, it’s bad for your penis size in a general way. 

As you saw above, it’s also bad for penis size in two very specific ways. 

So seriously. Pretty please…quit smoking.
