A varicocele occurs when a bulge results from enlarged veins inside the scrotum. The swelling typically resembles an enlargement above the testicle, without discoloration.
The testes are outside of the body because of the requirement for sperm production to be at two degrees cooler than the body. With a varicocele, the increased temperature in the testicles damages or kills the sperm.
Causes Of Varicocele
A varicocele occurs when veins in the scrotum become enlarged. Every vein has a valve that prevents blood from flowing backward, but sometimes the valve fails. This causes blood to flow back, damaging the vein and causing swelling.
Varicoceles often form during puberty. Varicoceles usually occur on the left side, most likely because of the position of the left testicular vein.
Doctors do not fully understand what causes the valves to fail and cause varicoceles. They are common and do not usually mean that a person has an underlying health problem.
Research published in 2014 found that smoking may be a risk factor for varicoceles, as it damages a person’s blood vessels. The same study found no link between alcohol or occupation and varicoceles.
Symptoms Of Varicocele
Often, a varicocele does not produce any symptoms. Rarely, it might cause pain. The pain may:
Vary from sharp to dull discomfort
Increase with standing or physical exertion, especially over long periods
Worsen over the course of a day
Be relieved when you lie on your back
Treatment Of Varicocele
Varicoceles that do not cause symptoms do not require treatment. A varicocele may need treatment when:
A man has a varicocele and a low sperm count or other problems with sperm. (SpermBoost treats low sperm count)
The varicocele is causing pain or swelling.
A couple has unexplained infertility, and the male has a varicocele
