Patient: My son, who is 20 years old, can feel a mass of striated veins on the surface of his scrotum. The doctor diagnosed varicocele, and he heard that this disease can affect male fertility. How can I treat it? Ans: Many patients with varicocele can have children normally, so suffering from varicocele does not necessarily affect fertility, the key to fertility is the degree of damage to the testicles, which can be determined by simple testicular examination and semen analysis, if the semen examination results are normal, you can temporarily disregard surgical treatment, regular semen routine examination every 3-6 months. In addition, for those male infertility patients who suffer from varicocele and have abnormal semen quality, varicocele may not be the only or main cause of infertility, only those who do not find other obvious abnormalities, but the semen quality and the deterioration of varicocele are progressively aggravated together, then it is highly suspected that varicocele affects male fertility. Only in those cases where no other significant abnormality is found and the quality of semen and varicocele deteriorate progressively, is there a high suspicion that varicocele is affecting male fertility, and only then is active intervention likely to have a satisfactory outcome.
