Strong: Testicles

Testicular Shrinkage

Testosterone is an anabolic hormone

A man's balls fill his underwear. They slap against his legs in exercise. Steroids make a man's testicles shrink in size. They become smaller and his underwear becomes looser. But usually the shrinkage is not profound.

Note:This is the experience of one man receiving testosterone injections prescribed by a practicing endocrinologist.

But:The anabolic steroids were not abused or used for non-medical purposes. The medicine used was Depo-Testosterone.

Testicular shrinkage on steroids: egg-sized and grape-sized

The shrinkage of my testicles was not profound. At first when I took testosterone shots and Androgel, my testicles became tighter and smaller by a small amount. They did not hang as far down in my underwear.

Then:The shrinkage progressed over the next year of testosterone shots. My balls continued to shrink in size.

Finally:My testicles were the size of small grapes. This is larger than raisins and peas—but smaller than eggs and walnuts.


Semen quality. The quality and also quantity of my ejaculate significantly decreased. When I ejaculated, only a small amount of fluid would appear. I noticed the fluid was less white. It was clear.

The testosterone replacement therapy also caused loose skin on my scrotum. Before TRT, my testicles would fill out my scrotal sack. After a year of TRT, my small testicles would not fill out the sack.

So:There was a lot of loose scrotal skin. I could grab several inches of it below my testes.

And:This was a strange sensation—it is not something I want to experience again.


Caution: exclamation mark

I was unhappy about the shrinkage of my testicles. They did not fill out my underwear as well as they used to. When looking at myself in the mirror, it became apparent my testicles were much smaller.

It almost seemed like I have none at first glance because my penis would completely block them. For some men testicular shrinkage due to anabolic steroids can cause depression. It made me feel unhappy.

Also:I was certainly not sexually interested. My testicles were this size before I had completed puberty.



How common is testicular atrophy from taking anabolic steroids? One study I found surveyed men who used anabolic steroids for non-medical purposes. It reported the rate of testicular shrinkage to be more than 50%.

Also:Other side effects from the anabolic steroids were reported. These men were not using testosterone replacement therapy.

Men reporting side effects:        96.4%
Testicular atrophy:                51.0%
Insomnia:                          47.7%
Depression:                        25.2%
Hypertension, high blood pressure: 19.0%

Before, after

There was a difference in the size of my testicles before and after testosterone injections. The testicles probably ended up about one third the size they originally were. Also I had at most half the ejaculate volume.

Testosterone Injections

Penis:Steroids do not affect penis size. My penis size was not affected by Androgel or Depo-Testosterone (testosterone cypionate).

Tip:Erections actually become harder when you become eugonadal—meaning your testosterone levels are normal for men your age.

Also:The testicles sometimes provide an important clue to a man's health status.

It is important to us to have that sack hanging between our legs. When the temperature is warm it slaps against our thighs as we walk and move. In a way we are emasculated when our balls shrink to a much smaller size.

However:For men with genuine medical problems, using testosterone is worthwhile. Low testosterone is a health problem.

And:It is not a lifestyle choice or something to endure. It is a disease condition.

But for men who are healthy, or near-healthy, having normal-sized balls in our shorts and filling our underwear is not something to deny ourselves.
Using exercise
and diet,
even strict diet,
to fix low T may be better overall.

Low Testosterone

And with our normal-sized balls, having a muscular and strong body is even better. A big sack, full of testosterone-producing Leydig cells, resting against our thick and strong legs—this is the ideal.

Big Legs


Testosterone replacement therapy was a necessary medical treatment. It was prescribed by my endocrinologist. I was fortunate that I only needed it a limited amount of time. TRT was unpleasant and made my testicles shrink.

Review:The testicular shrinkage I experienced was rapid but not profound: it was noticeable.
