Q: My husband was found to have a varicocele - What is that?
A: Varicoceles are enlargements of veins, inside the scrotum, that drain the testicles. They're found in 15% of all men, but in up to 40% of men in infertile couples. These venous enlargements may lead to a rise in temperature and a decrease in blood circulation through the testes and could negatively affect sperm production. A surgical procedure (varicocelectomy) can often correct this problem and improve sperm count.
