Tip #66: Varicocele


This image shows a man with a dilated vein in his left testicle.

Due to the pooling of blood in this vein, the temperature of the testicle may be elevated. This can lead to abnormalities in sperm count, motility or morphology (shape). Sometimes, varicocele surgery will improve a man’s semen analysis results, but it takes at least three months to see an improvement.
