"What Causes Varicoceles?"

A numerous amount of causes have been suggested for Varicoceles. Many of them include –

-    The valves in the veins may stop working.

-     If blood flow may be inactive.  

-    The longer veins from the testicles to the heart are interlinked.

Besides, if blood flows backward or pools in the veins, that may lead to swelling. 

Before digging into the causes, we need to understand the meaning of Varicocele. 

What are a varicoceles
A skin-covered bladder that carries the testicles is called as the scrotum. It is equipped with the arteries and veins that flow blood to the progenitive glands. Varicoceles happens when a vein in the scrotum leads to some twirl.  Varicocele can also be explained as the stretch of the veins inside the scrotum. Those veins are known as pampiniform plexus.

One can experience varicocele only in the scrotum, that is very identical to varicose veins in the leg. 

Varicocele may lead to:

-    Lowered sperm production and reduced quality. 

-    Causes infertility in some cases.

-    Shrinkage of testicles. 

Varicoceles are quite usual – 15 percent of the adult male population and almost 25 percent of the adolescent male population can suffer from this. Also, Varicoceles is more commonly detected in the males aging from 15 to 25 years of age.

Varicoceles can be formed at the time of puberty – more commonly, it affects the left side of the scrotum. Reason being, the anatomy of both the sides of the scrotum isn’t similar. 

What leads to varicocele formation?
Anatomically,  spermatic cord carries the testicles. Also, the cords are consisting of veins, arteries, and nerves that act as support to the glands. If we talk about the healthy flow of veins, valves carry the blood from the testicles to the scrotum, and then they move it back towards the heart. 

Sometimes the disturbed blood flow causes scrotum to enlarge. A varicocele happens gradually over time.

Possible complications
Varicocele may have adverse effects on fertility. 

Primary fertility is identified if a couple hasn’t conceived even after trying for one year. On the other hand, secondary infertility is suggested when a couple conceived for once but can’t have a 2nd child. 

Symptoms
The signs or symptoms are hard to recognize as varicoceles do not cause much pain. However, in some instances, it might cause: 

•    Discomfort around the area that may also lead to mild pain. 

•    Standing over long periods may even worsen the condition. 

•    A long day may cause further discomfort. 

•    Affected fertility.


Over a period, varicoceles might become more challenging and noticeable. A swollen testicle on the left side becomes quite apparent. 

Living with a varicocele
If there have been long-term complications in pregnancy planning, the couple must consult their reproductive specialist.  Surgery can be an option if the couple is trying to conceive a child and there has been pain around that area.  

The specialist may want to conduct a scrotal ultrasound, to measure the spermatic veins.  If the patient delivers a fair and accurate picture of the condition, the treatment goes quite easy and successful.
