Nancy Wang from Stanford University is a urologist and says, “Varicoceles which are varicose veins of the spermatic cords, are associated with low testosterone. This in turn makes men more likely to develop metabolic risks and heart disease. No one has connected the dots before now”.
These men have higher risks of heart disease, diabetes, and hyperlipidaemia.
My comment: Varicoceles feel just like a bag of worms in the scrotum. Up to one in 5 men will develop these over their lifetime.
