Varicoceles are veins in your scrotum that have expanded, or dilated. The condition
is much like varicose veins that occur in the legs.
When veins inside the spermatic cord aren't working properly, it can cause the veins
to swell. The spermatic cord join each testicle to the body. Veins in the cord normally
take blood back to the heart, and tiny valves inside the veins keep the blood flowing
in the right direction. Valves that don't fully close allow the blood to flow sluggishly
or pool inside the veins, much like water in a dam. This buildup of blood causes the
Varicoceles most often occur in the left testicle. This could be because the sharp
angle at which blood from the scrotum enters the kidney veins can cause pressure to
build up in the scrotum.
What causes varicoceles?
There are several reasons why varicoceles develop. Valve deformities or missing valves
in the veins in the scrotum are one possibility. Because male teens grow so rapidly,
the testicles need more blood than usual. If the veins have even small abnormalities,
they may not be able to easily shuttle the extra blood back to the heart.
Other anatomical problems may also increase the pressure inside the veins, resulting
in swelling. In rare cases, swollen lymph nodes can impede blood flow in the veins
of the scrotum and cause pain.
What are the symptoms of varicoceles?
Most boys, and men, with varicoceles don't have any symptoms. When they do occur,
symptoms can include:
Heavy sensation in the testicles that gets worse during or after exercise
Scrotal sac in which swollen blood vessels can be felt
One testicle that is smaller than the other
Persistent, dull ache in the scrotum
How are varicoceles diagnosed?
Doctors can usually diagnose varicoceles with a physical exam of the testicles. An
ultrasound scan may be done to create images of the testicles.
Can varicoceles affect fertility?
About 40% of all men who are tested for infertility are found to have varicoceles.
This leads to sperm that are less able to move and swim toward an egg, which is called
reduced sperm motility.
Treatment of infertility may include surgery or another technique to take out or block
the vein with the varicocele. Testing shows that most men are producing healthier
sperm within about 6 months of surgery.
Pain relief and treatment in teens
Some men with varicoceles have testicular discomfort or pain. Pain-relieving measures
Lying flat on the back, a position that helps the blood flow in the right direction
and drain the scrotum
Wearing undergarments that support the scrotum, including an athletic supporter or
Using pain-relievers, including ibuprofen or acetaminophen
Varicoceles in teens don't usually require treatment, unless there is significant
testicle shrinkage, potential fertility issues, or debilitating testicle pain. Doctors
may suggest surgical treatment if the testicles are of noticeably different sizes.
Surgery in teen can restore proper blood circulation in the scrotum and help preserve
