Varicocele is a common condition that affects many men notably young adults. It happens when the veins inside the scrotum which is the loose skin that holds the testicles become enlarged. You can think of it like varicose veins that present in legs but in this case they are in the scrotum.
Lot of men do not even know that they have varicocele because on average it does not cause any problems.Sometimes varicocele can trigger uneasiness and even problems with fertility.Varicocele is something that men should know. So it is important to understand causes of varicocele and how it develops.
What Is Varicocele in Simple Words?
Before we talk about causes let us understand it in an easy way. Inside your scrotum there are veins that carry blood away from testicles. These veins have small valves that keep blood flowing in right direction. When these valves do not work properly blood can flow backward and collect in the veins.This causes the veins to swell leading to varicocele.
Main Causes of Varicocele
There is not just one single cause of varicocele. Instead it happens due to a combination of factors. Given below are most common causes explained in very simple ways.
1. Weak or Damaged Vein Valves
This is the most common cause.
Veins have tiny valves that open and close to control blood flow. When these valves become weak and stop working properly blood does not move smoothly. Instead it starts to pool in the veins.
This extra blood causes pressure and makes the veins larger which leads to varicocele.
2. Poor Blood Flow in the Veins
Sometimes the blood flow in the scrotum becomes slow or blocked. When this happens blood cannot move out properly and starts to build up in the veins.
This pressure causes the veins to stretch and become swollen over time.
3. Pressure in the Abdominal Area
Increased pressure in the lower abdomen can also lead to varicocele. This pressure can affect how blood flows through the veins.Some common reasons for this pressure include.
- Heavy weight lifting
- Long hours of standing
- Straining during bowel movements
When pressure builds up it can stop normal blood flow and cause veins to enlarge.
4. Structure of the Left Testicular Vein
Varicocele is more common on left side of scrotum. This is because that how veins are arranged in the body.The left testicular vein connects in a different as compared to right one. This structure can create more pressure on the left side making it easier for blood to collect there.That is why most varicocele cases take place on left side.
5. Hormonal Changes During Puberty
Varicocele mostly grows during teenage development stage. This is the time when body is growing quickly and blood flow to testicles increases.This sudden increase in blood flow can put extra pressure on veins. If valves are already weak this can lead to swelling of veins.
6. Genetic or Family Factors
In some cases varicocele may run in families. If someone in your family has had vein problems and varicocele you may have a higher chance of developing it.This happens because some people are born with weaker vein walls or valves.
7. Tumors or Rare Medical Conditions
In rare cases a tumor in the abdomen and kidney can press on the veins and block blood flow. This can lead to sudden varicocele especially in older men.However this is not a common cause. Maximum varicocele situations are safe and not connected to serious diseases.
Risk Factors You Should Know
Some elements can enhance chances of getting varicocele.
- Being a teenager or young adult
