Varicocele: It's not clear how varicoceles affect fertility. The testicular veins cool blood in the testicular artery, helping to maintain the proper temperature for optimal sperm production. By blocking blood flow, a varicocele may keep the local temperature too high, affecting sperm formation and movement (motility).
