A recent meta-analysis, however, examined the various techniques for varicocele repair including angioembolization.[sup.5] Over a 20-year period the authors identified 3319 men who underwent surgical varicocele repair and 314 men who underwent varicocele embolization for clinical varicoceles and male factor infertility.
Our objective was to review the failure rates of varicocele embolization done for male factor infertility at the University of Toronto, Toronto, Ontario, and to examine how these rates compare with those published for varicocele embolization and surgical varicocele repair.
A total of 158 patients were identified between 2004 and 2008 that had undergone unilateral or bilateral varicocele embolization for male factor infertility.
In total, 88 men (56%) underwent attempted bilateral varicocele embolization, 68 men (43%) underwent attempted unilateral left varicocele embolization, and 2 men (1.3%) underwent attempted right varicocele embolization.
