Why does varicocele tend to occur on the left side?

Varicose veins will bring a heavy psychological burden to patients, and male friends should pay great attention to it. Varicose veins are a common disease symptom in young men, often occurring on the left side, and are one of the important causes of male infertility.

Why does varicocele tend to occur on the left side?

Varicose vein varicocele is caused by obstruction of the venous return of the spermatic cord or valve failure. The blood reflux causes blood stasis, resulting in tortuosity and dilation of the varicocele. Varicose vein varicocele often occurs within the course of the internal spermatic vein. The main cause is obstruction of the internal spermatic vein. In recent years, varicocele venography has found that the incidence rate on the left side is much higher than that on the right side. The reasons are as follows:

1. The left internal spermatic vein is located behind the sigmoid colon and is easily compressed by intestinal feces, affecting blood return.

2. The left internal spermatic vein anastomoses with the left renal vein at a right angle, while the right internal spermatic vein anastomoses with the inferior vena cava at an oblique angle, and the blood flow is relatively smooth.

3. The left internal spermatic vein is long and enters the renal vein at a right angle, so blood flow is subject to a certain resistance. The left internal spermatic vein near the left renal vein has no valve, so blood can easily flow back.

What are the symptoms of varicocele?

1. Swollen blood vessels like earthworms can be felt or seen in the scrotum, which is called "worms in a bag" in the medical field. The scrotum or testicle on the affected side has a swollen feeling or pain, and the scrotum is enlarged. When standing, the scrotum and testicle on the affected side are lower than the healthy side. Dilated and tortuous veins can be seen on the surface of the scrotum. There is a soft mass like an earthworm when touched. The symptoms are more obvious when standing for a long time or exerting force on the abdomen. Lying flat can alleviate or eliminate the symptoms. Sitting for a long time will cause the local temperature of the spermatic cord to rise and cause swelling and pain.

2. Patients may have symptoms of neurasthenia, such as headache, fatigue, neurasthenia, etc. Some patients have sexual dysfunction.

3. The patient may have no symptoms at all and the disease is only discovered during physical examination.

Clinically, varicocele can be divided into three degrees:

Grade 1 (mild): When standing, no varicose veins can be seen protruding from the scrotal skin, but the varicose veins in the scrotum can be felt. The varicose veins disappear quickly when lying down.

Grade 2 (moderate): When standing, dilated venous protrusions can be seen on the scrotum, and more obvious varicose veins can be felt inside the scrotum. The mass gradually disappears when lying down.

Grade 3 (severe): There are obvious large blood vessels on the surface of the scrotum, obvious earthworm-like dilated veins in the scrotum, and the venous walls are thickened and hardened; it disappears slowly when lying down.

Experts say: The harm of varicocele cannot be ignored. Some patients may experience mental anxiety, anxiety, insomnia, general fatigue, impotence and other symptoms with mild adverse reactions. Severe varicocele can cause atrophy of the testicle on that side. Patients often come to the doctor because of small testicles. In addition, varicocele is one of the important causes of male infertility. At the same time, it may cause orchitis, prostatitis, etc. over time, thus affecting sexual function. Therefore, if you have symptoms, it is better to go to a regular hospital for treatment as soon as possible! Avoid unnecessary harm!
