Vasectomies may cause prostate cancer and lower testosterone

Prostate cancer is one of the most over-treated and yet poorly treated cancers.

It is so common that if they live long enough, most men will get prostate cancer.

But it’s usually best to leave it untreated.

It can sit there doing absolutely nothing for years — in fact, it often does nothing to hurt you at all.

You still don’t want to make it worse though.

So you need to know what can make prostate cancer worse and then avoid those things.

One of the things that you do not want to do is have a vasectomy.

I have a study for you today that shows vasectomies can increase the likelihood of getting prostate cancer quite dramatically.

It may be too late for you, but here’s a good reason not to consider a vasectomy at all.

Vasectomy is a much bigger deal than just snipping a couple tubes.

But before we get to that, let’s look at a rat study.

It’s easier to see the effect of vasectomy and a rat than on a human man.

Rats don’t live as long and go through their life stages much quicker than we do.

So, we can observe changes quite easily and quickly in rats where we couldn’t in a human being.

If you think a vasectomy is simply a harmless procedure, this may rapidly change your mind.

Vasectomy caused:

testicular and epididymal hypertrophy, formation of pathologic vas deferens granulomas [tumors]…increased numbers of neutrophils and large lymphocytes and decreased numbers of small lymphocytes and basophils.

And the effects got worse as the rats aged.

You can see from these effects that a vasectomy has a dramatic effect on the entire body.

These changes were not just local to the prostate or the testicles, either.

These changes affected the entire body.

Now let’s look at a study in human males.

This study focuses on prostate cancer.

It turns out that the truth about vasectomy is that it can practically double your risk for prostate cancer.

And that’s just one of the side effects from vasectomy.

Among men who had their vasectomy 20 or more years in the past, the relative risk of prostate cancer was 1.89, and after excluding stage A and B cases, the relative risk was 2.06.

Stage A is early prostate cancer that is very localized.

Stage B is more advanced, but it still has not spread outside the prostate.

You won’t see the stages detailed this way in most newer studies, but they use it here.

This study showed clearly that a vasectomy increases your chances of getting prostate cancer.

And it approximately doubles your chances of getting more advanced or severe prostate cancer.

Let’s return to a different rat study to see why this may be happening.

In this case, they vasectomized some rats.

And they performed what is called a sham operation on some others.

The sham operation is where they do the same surgery but without the vasectomy.

Then researchers compared the two groups of rats over a long time in rat years.

Vasectomy gave rise to a high incidence (7 in 8) of bilateral granuloma formation of the vas deferens which varied in size.

A granuloma is a tumor-like mass of immune cells.

It is a sign of a massive autoimmune reaction.

The vas deferens carries semen and sperm from the testicles out of the penis.

In a vasectomy, the testicles still produce sperm, and the prostate gland continues making prostatic fluid.

But the two never mix — the sperm can’t escape the testicles, so semen does not contain any sperm.

To continue with the discoveries of this rat study:

Vasectomy led to decline in testis weight and endocrine function as witnessed by a marked depression of the levels of androstenedione and, in particular, of testosterone.

That’s not good.

That means that many of the important male hormones are lower in the vasectomized rats.

Maybe men who have had a vasectomy have lower T levels, too.

So the men have to deal with the side effects of both the vasectomy and testosterone levels that are too low.

And they may have lower male androgens and a higher auto-immune response in their genitals too.

And there could be other vasectomy health risks we haven’t discovered yet.

These results are a good reason why you don’t want to get a vasectomy no matter what they say.

And if you’ve had a vasectomy — you want to be super alert for changes.

Some changes signal fibrosis, low testosterone, and other problems in the body.
