To determine whether repair of subclinical varicoceles in the right testicle results in significant seminal improvement in patients with clinical left varicocele.
Patients were divided into two groups: Group I (unilateral varicocelectomy) and Group II (bilateral varicocelectomy-subclinical left varicocele). The mean sperm concentration before treatment was higher in Group I (21.01 +/- 19.1) compared to Group II (5.7 +/- 10.7) (p = 0.04).
An increase in volume was detected in the left testicle of patients in Group I (17 +/- 7.9 vs. 22.81 +/- 8.2; p = 0.04) and in the right testicle of patients in Group II (18.4 +/- 6.2 vs. 22.3 +/- 6.5; p = 0.04). Although the mean postoperative sperm concentration in Group I increased slightly (25.7 +/- 22.8), the mean sperm concentration in Group II increased significantly (30.32 +/- 9.8; p = 0.03). Pregnancy rate was higher in Group II (66.7%) compared to Group I (33.3%).
Even a small, subclinical unrepaired varicocele continues to have a detrimental effect on bilateral testis function in a patient with grade II-III left varicocele.
确定修复右侧睾丸亚临床型精索静脉曲张是否能使临床左侧精索静脉曲张患者的精液质量得到显著改善。
患者分为两组：第一组（单侧精索静脉结扎术）和第二组（双侧精索静脉结扎术——亚临床型左侧精索静脉曲张）。治疗前，第一组患者的平均精子浓度（21.01±19.1）高于第二组（5.7±10.7）（p = 0.04）。
第一组患者左侧睾丸体积增大（17±7.9对22.81±8.2；p = 0.04），第二组患者右侧睾丸体积增大（18.4±6.2对22.3±6.5；p = 0.04）。虽然第一组术后平均精子浓度略有增加（25.7±22.8），但第二组平均精子浓度显著增加（30.32±9.8；p = 0.03）。第二组的妊娠率（66.7%）高于第一组（33.3%）。
对于患有II - III级左侧精索静脉曲张的患者，即使是微小的、未修复的亚临床型精索静脉曲张也会持续对双侧睾丸功能产生不利影响。
