Varicocele is the enlargement of veins of the spermatic cord, usually seen on the left side of the scrotum in adolescent males. This is a normal occurrence, and seldom requires surgery.
The veins on the affective side of the scrotum become full. This condition presents a slightly purplish color, feels like a bundle of worms in a plastic bag, and produces a dull sensational pain in the groin.
Very large veins can present some discomfort, reduce the quality of semen, and create a condition known as azoospermia… absence of sperm in the semen.
Varicocelectomy, excision of a portion of the scrotum sac with ligation of the dilated veins to relieve varicocele, can induce spermatogenesis… the transformation of a spermatid to a functional spermatozoon. But the fix can very well be temporary.
Studies have shown a 60% relapse to varicocele. According to Reuters Health News, about one-third of infertile males are indicative of varicocele.
