Patients with oligozoospermia show a reduction in the semen quality, independent of the etiology of the disturbance.
To investigate the role of the varicocele in the decrease of the semen quality in oligozoospermic men.
Ten patients with left clinical varicocele (termed PCV) and 21 patients without this entity (termed PSV) attended in a private laboratory from Petrópolis, RJ, were investigated. Sperm count, vitality, motility, and morphology of spermatozoa were examined and the results were compared between them and a control group consisting of 15 patients without clinical varicocele and with normal spermiogram.
PCV and PSV had showed significant decrease in the vitality (43.9% and 34.9% versus 73.0% in the control group), grade (a) (5.3% and 2.4% versus 32.4% and grade (d) (76.7% and 83.8% versus 44.9%) of sperm progression and in the percentage of oval sperms (25.5% and 22.9% versus 61.2%), amorphous head (25.4% and 23.8% versus 12.5%) and other anomalies (23.8% and 30.5% versus 13.0%). PCV had also showed significant difference in the percentage of tapered sperm (10.9% versus 1.3%), whereas PSV had showed significant difference in the grade (b) of sperm motility (11.0% versus 22.0%), both in regard to the control group. Between PCV and PSV had not been found significant differences.
Varicocele reduces the semen quality in oligozoospermic men, but this reduction also occurs in oligozoospermia of any etiology.
少精子症患者精液质量下降，与干扰病因无关。
研究精索静脉曲张在少精子症男性精液质量下降中的作用。
对来自里约热内卢彼得罗波利斯一家私人实验室的10例左侧临床精索静脉曲张患者（称为PCV）和21例无此病症患者（称为PSV）进行研究。检查精子计数、活力、运动能力和精子形态，并将结果与由15例无临床精索静脉曲张且精子图正常的患者组成的对照组进行比较。
PCV组和PSV组在活力（分别为43.9%和34.9%，对照组为73.0%）、精子前进分级（a级分别为5.3%和2.4%，对照组为32.4%）和d级（分别为76.7%和83.8%，对照组为44.9%）以及椭圆形精子百分比（分别为25.5%和22.9%，对照组为61.2%）、无定形头部（分别为25.4%和23.8%，对照组为12.5%）和其他异常（分别为23.8%和30.5%，对照组为13.0%）方面均有显著下降。PCV组在锥形精子百分比方面也与对照组有显著差异（10.9%对1.3%），而PSV组在精子运动b级方面与对照组有显著差异（11.0%对22.0%）。PCV组和PSV组之间未发现显著差异。
精索静脉曲张会降低少精子症男性的精液质量，但这种质量下降在任何病因的少精子症中也会出现。
