Meet Mr. Varicocele



This is no unicorn
Varicocele: Unicorn or workhorse?

How can something so soft and warm and blue, and no wider than a pencil, have such a devastating effect on your ability father children? Meet the varicocele (veri-ko-seal), the unicorn of male fertility.

The Inimitable Varicocele

As posted previously, the varicocele is unique to humans and is a consequence of our upright posture. It is a bag of veins in the scrotum that, except if it caused low-grade discomfort, you probably would never know you have.

Varicocele as Unicorn

Yet, as I live and breathe the nuances of this field daily, the varicocele never ceases to amaze me.  Although first recognized in the first century AD, it gained modern notoriety when a Dr. Tulloch surgically repaired one in the 1950s in a man who had no sperm in his ejaculate. Lo and behold, sperm returned to the ejaculate and the patient’s wife conceived naturally. Is this the story of a unicorn?

Not really. Unlike the ephemeral unicorn, the varicocele exists and is, in fact, quite common. Look hard and you will find them in 15% of healthy men and in 40% of men having trouble conceiving their first child. It is even more common in men having trouble having a second child. Having said this, it is also true that most men with varicoceles are normally fertile. So how does this work?

A Susceptibility Thing

No one really knows why varicoceles affect the fertility of some men but not others. Maybe it’s the size of the lesion or maybe it’s the exposure time (time from their onset at puberty to the age at which men try to conceive) that matters. As a consequence, some clinicians don’t believe in them and others, like me, do. In fact, I have spent a great deal of time pondering them in infertile men. Because of this, I feel I know their personality quite well.

The Varicocele Personality

Having read, studied and published on the varicocele over the last 2 decades, here is my letter of recommendation about varicoceles:

Dear Parent to Be:

I am delighted to write this letter of support about Mr. Varicocele, someone whom I have known well for the last 20 years and feel comfortable commenting on his personality and future potential.

      1. In most men, he coexists peacefully and never bothers anybody.
      2. In some men, he disturbs sperm production and can wreak havoc on fertility.
      3. Fixing him can help couples conceive naturally
      4. Fixing him can help eliminate scrotal pain
      5. Fixing him fixes a problem and can help couples build entire families (i.e. have several children)
      6. Fixing him can help couples considering IVF for family building to avoid IVF and conceive naturally
      7. Fixing him can help couples considering IVF to have children to use less invasive technology (i.e. IUI) instead of IVF to conceive
      8. Fixing him in men who fail to conceive with IVF can help with IVF conceptions
      9. Fixing him in men with genetic causes of infertility will not help them conceive naturally
      10. Fixing him in men with no ejaculated sperm counts will generally not help them conceive naturally but can help them conceive with IVF

In summary, I believe in Mr. Varicocele has the potential to have a great impact on the world of human fertility. Please consider him seriously whether you are simply contemplating, or actually building, your family as he can be invaluable in these situations. Personally, I recommend him highly to as one of the most common correctable conditions associated with infertility. Please call me if you have any questions about this rather strong recommendation.

Sincerely yours,

Paul Turek MD

Director, The Turek Clinic

    Hi Dr Turek,
    I find this blog very interesting. My husband had a uncessessful TESA about six months ago and we were told that the found no sperm cells or cells that can become sperm and therefore he will never father his own child. At the time I asked our doctor about a varicocele that another specialist had pointed out in a recent visit and was told that this had would have nothing to do with his azoospermia. Just wondering your thoughts on this or should we get a second opinion?

    I guess what I’m asking is can a varicocele cause total NOA? I know it can decrease sperm count but can it stop production entirely?

    I recently had a left side varicocele repaired by Interventional Radiology hoping that it would boost my testosterone levels. I didnt have any problems with fertility, but lowT and scrotal pain. Unfortunatly after 3 months my T levels did not increase, but what did occur was remarkable. Within 1 week of the surgery I went from being practically an insomniac to sleep soundly through the night. I havent seen this published anywhere, but I have a hunch many men with unidentified sleep problems may be related to undiagnosed varicoceles.

      Samson, interesting. Maybe the scrotal pain was preventing you from getting good sleep and now that is gone. Either way, better sleep may also increase your testosterone levels.

      Dear Al, Anything that reduces the pain/discomfort of a varicocele is good. The real question is whether the varicocele is potentially affecting your future fertility (if that is an issue at all!). A semen analysis may be of help here. As long as the discomfort is under control and the semen analysis remains normal, you should be good to go.
