Varicocele can sometimes affect fertility. Nine percent of people with varicocele have infertility, and 39 percent of male infertility is caused by varicocele. In severe cases, it can cause testicular atrophy. The cause is an increase in temperature in the scrotum on the affected side that is reflected to the opposite side, causing degeneration and atrophy of the spermatogonia and a decrease in the number of spermatozoa. Although there is no medical evidence linking body size to varicocele, it may be due to a right-angle shape of the spermatic vein returning to the left renal vein, which interferes with the return of blood. Varicocele causes progressive impairment of testicular function and reduced fertility from puberty in some patients, but this impairment only becomes apparent if their partner’s fertility is also reduced. Clinically, it has been found that tall, thin individuals are more likely to develop this disorder. Although there is no medically proven association between body size and varicocele, it may be because the spermatic vein returns to the left renal vein at a right angle, which affects the return of blood. For secondary varicocele, attention should be paid to the examination of the abdomen, and an intravenous pyelogram should be performed to rule out renal tumors. Laparoscopic spermatic vein high ligation, small trauma (umbilical incision 1cm, double lower abdominal incision 0.5cm, short surgery time, bilateral ligation can be completed in 8-10 minutes, the surgical field is enlarged, easy to distinguish the arteries and veins, not easy to damage the arteries and lymphatic vessels, after surgery does not affect the testicular arterial blood supply and lymphatic flow, the incidence of testicular atrophy, scrotal edema and syringomyelia is greatly reduced, the recurrence rate is low The recurrence rate is about 1%.
