The role of surgery in reducing sperm abnormality rate is mainly determined by the cause of the disease. Surgery is more effective when the cause is varicocele or vasovaginal obstruction; surgery is less effective when the cause is simple inflammation or abnormal androgen levels. Varicocele can cause localized temperature rise, which further affects sperm shape and leads to increase in sperm deformity rate; vas deferens obstruction, which affects sperm discharge, and long time sperm storage in seminal vesicles, which also affects sperm deformity. The above problems can be treated by surgery, which can change the sperm malformation rate. The presence of seminal vesiculitis and epididymitis can also cause the sperm deformity rate to rise, which can be recovered mainly through anti-infection treatment; the lowering of androgen level can also cause the sperm deformity rate to rise, which needs to be regulated by the application of testosterone. Surgery is basically ineffective in treating the above causes of sperm deformities. Once you find a significant increase in the sperm abnormality rate, you need to consult a doctor in time to diagnose the condition and then carry out standardized treatment, so as to avoid delaying the condition.
