What is the definition or description of: varicocele?

Swollen veins: A varicocele is an enlargement of a network of veins called the pampiniform plexus which is part of the spermatic cord. This can give rise to discomfort and a "bag of worms" appearance of the scrotal skin. They may contribute to infertility or decreased testicular function (atrophy) and repair may be advised depending on the circumstances. There are effective surgical and nonsurgical options.

Scrotal varicosity: Varicose spermatic cord veins within the scrotum. Usually left sided & due to absent or faulty venous valves between testis and major vessels permitting beack pressure effects on spermatic veins. Can cause infertility in some, but mostly of no consequence. Best treated by urologist if associated with pain which is rare, or there is an unpleasant heavy draggy feeling.
