One of the concerns of many patients who come to the clinic with varicocele is why he has this disease, and the following is an introduction to the causes of varicocele.
There are two main causes of varicocele: congenital anatomical factors and acquired factors. Congenital anatomical factors: The left internal spermatic vein is injected into the left renal vein at a right angle and is compressed by the sigmoid colon in front, and the left renal vein passes between the aorta and the superior mesenteric artery. When standing or connective tissue relaxation, the superior mesenteric artery squeezes the left renal vein, forming a proximal clamp phenomenon (also called nutcracker syndrome or left renal vein compression syndrome, mostly seen at the age of 13 to 16 years old, mainly because of faster pubertal development, rapid height growth, spinal hyperextension, rapid change in body shape or renal prolapse, etc., the angle between the superior mesenteric artery and the aorta becomes smaller, compressing the renal vein This is caused by the compression of the renal veins by the superior mesenteric artery.) The right common iliac artery sometimes also compresses the left common iliac vein, forming a distal clamping phenomenon. Normal left internal spermatic vein has a valve at the entrance into the left renal vein to prevent reflux, if the venous valve enters the left renal vein has a valve to prevent reflux, if the venous valve is underdeveloped or the smooth muscle or elastic fiber of the vein wall is weak, it will also lead to varicose spermatic vein, this varicose due to anatomical factors becomes primary varicose spermatic vein. Mao Xiangming, Department of Urology, Peking University Shenzhen Hospital Acquired factors: mainly retroperitoneal tumor, renal tumor, hydronephrosis or vagal vessels compressing the inner spermatic vein, cancer embolism or other reasons causing obstruction of renal vein or inferior vena cava, so that the return flow of blood to the inner spermatic vein is obstructed, which can cause secondary varicocele. As for whether excessive sexual desire and excessive frequency of sex are related to varicocele, there is no data to prove the correlation, or the correlation is not significant; however, some data show that high-intensity sports (basketball, soccer, etc.) may accelerate the progression of varicocele, but do not increase the risk of varicocele.
