Foreword: varicocele – unraveling the enigma

It was more than 40 years ago, as a first-year Urology resident, that I performed my first varicocele ligation (a Palomo procedure1) under the watchful eye and able hands of my staff physician. I dutifully read all I could the night before the procedure and became familiar with the names of Barfield, Macomber and Sanders, Tulloch, MacLeod, Ivanissevich, Palomo, Amelar and Dubin and others who had written about varicoceles being associated with abnormal semen parameters and a potentially surgically correctable cause of male infertility. During and after our uneventful surgical procedure, I was grilled as to the anatomy and known pathophysiology of a varicocele. I felt well-versed from my reading and proudly regurgitated all I had learned about the anatomy of the left testicular vein and pampiniform plexus, incompetent or absent valves in the vein, increased testicular temperature, sluggish flow of blood from the left testis and possible toxins from the opposing left adrenal gland vein entering the dilated, incompetent testicular vein – any or all of which could contribute to disturb spermatogenesis and cause infertility. It all seemed simple enough! I pretty much thought we knew all we needed to know about this so-called “bag of worms.”
