Right subclinical varicocele: how to manage in infertile patients with clinical left varicocele?

In this prospective study, we compared the results of bilateral varicocelectomy and left varicocelectomy for treatment of infertile patients with subclinical right and clinical left varicoceles with oligoasthenospermia. Because there was more improvement in semen parameters and pregnancy rate in patients who underwent the bilateral surgery, we concluded that right subclinical varicocele should be surgically treated in conjunction with the left one.
