The association of varicoceles and subfertility has been well documented. Although varicoceles remain the most common surgically correctable cause of male infertility the diagnosis of small varicoceles remains a challenge. We evaluated 40 men with an isotope blood pooling scan. Seven volunteers served as either positive or negative controls. Complete correlation between physical findings and the isotope scan was found. The 6 patients with obvious clinical varicoceles and a stress pattern on semen analysis all had positive scans. The 18 patients with a stress pattern and who were clinically suspected of having a varicocele all had positive scans. Of 9 patients evaluated for infertility with a stress pattern but no clinical evidence of varicocele 6 had positive scans. We believe that the isotope scan will prove to be a useful procedure in the detection of nonpalpable varicoceles in selected subfertile men.
精索静脉曲张与生育力低下之间的关联已有充分记载。尽管精索静脉曲张仍是男性不育最常见的可通过手术矫正的病因，但小精索静脉曲张的诊断仍是一项挑战。我们对40名男性进行了同位素血液池扫描评估。7名志愿者作为阳性或阴性对照。发现体格检查结果与同位素扫描完全相关。6例临床精索静脉曲张明显且精液分析呈应激模式的患者扫描均为阳性。18例精液分析呈应激模式且临床怀疑患有精索静脉曲张的患者扫描也均为阳性。在9例精液分析呈应激模式但无精索静脉曲张临床证据的不育评估患者中，6例扫描为阳性。我们认为，同位素扫描将被证明是检测部分生育力低下男性中不可触及的精索静脉曲张的一种有用方法。
