What are varicoceles?

Varicoceles occur when a particular type of vein in the scrotum, known as the pampiniform plexus, enlarges. One of the functions of these veins is to drain blood out of the testicles in order to keep the testicles at a temperature suitable for making sperm. This enlargement occurs during puberty and can grow larger over time.


The enlargement of these veins does not usually cause any discomforts but may cause infertility or the slower growth of one of the two testicles. In certain cases, there may be mild aches that can be felt if there is swelling.

How are varicoceles found?

Varicoceles can be detected through a self-examination or a physical examination by a doctor. An ultrasound will also be done if the doctor finds abnormalities during the physical examination.


During the physical examination, your doctor may get you to hold your breath as this makes it easier to find any enlarged veins.


Your doctor may also proceed to conduct an ultrasound scan if abnormalities are found during the physical examination.

Varicocele treatment

Varicoceles do not usually require any treatment. However, treatment may be recommended if it accompanies fertility problems, pain or abnormal growth of one of the testicles.


Varicoceles are usually treated by surgery and your doctor may either perform an open surgery using a surgical microscope for assistance. Alternatively, a laparoscopic surgery may be done. This method employs the use of an instrument called a laparoscope that has a camera attached at the end for guidance.


Another possible treatment method is a percutaneous embolization. This is a non-surgical method that is performed by a radiologist. A balloon or coil is inserted into the veins and expanded to block blood flow in the area and reduce the size of the varicocele.
