refers to one or more enlarged veins in the scrotum, the loose pouch of skin that contains the testicles. Similar to a varicose vein in the leg, varicoceles are caused by a defect in one or more valves that help the blood to flow upwards. The defective valve causes blood to pool, making the vein swell. Affecting about 20% of men aged 15-25, varicoceles usually develop above the left testicle and occasionally in both.
While a varicocele often causes no symptoms, it is the most common cause of sperm production problems that can lead to male infertility. Some 40% of infertile men have a varicocele and about 80% of those who have already fathered a child but are now infertile have one.
Most varicoceles do not cause symptoms and often go unnoticed until a physical exam or a fertility work-up. Symptoms may include;
Aching or feeling of heaviness in the testicle, especially after standing for a long time
Atrophy (shrinkage) of the testicle
Visible or enlarged veins that may look like "a bag of worms"
Doctors suspect that varicoceles can cause infertility in some men by raising the temperature in the testes, which may damage or destroy sperm. However, many men with varicoceles do not have fertility problems.
In most cases, your doctor can detect the varicocele through a physical exam. He may ask you to take a deep breath and bear down (called the valsalva maneuver) to improve detection. If the exam is not conclusive, he may order an ultrasound of the testicles to provide a painless view of their internal structures.
Often times, varicoceles don't require treatment. If you experience pain or atrophy of the testicle or if you are infertile, you may wish to undergo one of several treatments:
The most common procedure to treat varicoceles. An incision may be made in your groin (inguinal canal), in your abdomen or below your groin so that your urologist can tie off the affected vein(s) and allow blood to be redirected to the unaffected veins. The outpatient procedure usually involves local anesthesia and few complications. A small percentage of men may get hydrocele (fluid build up in the testicle) or have a recurrence of the varicocele.
Less often used because it can present more risks. This procedure may have the advantage of identifying veins higher up, where your surgeon likely will need to tie off fewer veins. The urologist makes several tiny incisions in your abdomen, using tiny instruments under general anesthesia to repair the varicocele.
**You cannot expect to restore fertility for at least 3-4 months after the procedure, as sperm take about 8 weeks to generate. The procedure does not guarantee fertility; Please inquire within to fully understand your potential risks and benefits.
