Varicoceles as a common cause of male infertility are treated either by surgical ligation or, more recently, by angiographic occlusion of the spermatic vein. In the present prospective randomized study 38 patients were treated by surgical ligation and 33 by angiographic embolization. During the 12-month follow-up period a significant increase in sperm number (at 3 and 12 months) and sperm motility (at 12 months) occurred in both groups while sperm morphology remained unaffected. Altogether, 22 pregnancies (31%) were reported within the year following treatment, of which 11/38 (29%) occurred in the ligation group and 11/33 (33%) in the embolization group. Thus both treatment modalities appear equivalent, whereby embolization has the advantage that it can be performed on an outpatient basis.
精索静脉曲张作为男性不育的常见原因，可通过手术结扎治疗，或者最近采用的精索静脉血管造影闭塞术治疗。在本前瞻性随机研究中，38例患者接受了手术结扎治疗，33例接受了血管造影栓塞治疗。在12个月的随访期内，两组患者的精子数量（3个月和12个月时）和精子活力（12个月时）均显著增加，而精子形态未受影响。治疗后一年内共报告了22例妊娠（31%），其中结扎组为11/38（29%），栓塞组为11/33（33%）。因此，两种治疗方式似乎等效，而栓塞术的优势在于可在门诊进行。
