Varicocele is one of the main and surgically repairable causes of male infertility, which arises from dilatation and torsion of the testicular veins in the plexus pampiniformis. In this study, we examined semen samples from 40 patients diagnosed with varicocele between the ages of 15 and 30 years, according to WHO criteria (pre-operatively, and at 3, 6, and 12 months post-operatively). The mean spermatozoa concentration was found to be 45.25 ± 34.83 million/ml pre-operatively, while the mean post-operative concentration was 48.85 ± 35.73 million/ml at three months, 51.72 ± 32.82 million/ml at six months, and 49.63 ± 28.05 million/ml at 12 months (P > 0.05). The mean rate of A + B motile spermatozoa was 35.5 ± 14.71% pre-operatively, 42.65 ± 16.80% at three months, 43 ± 13.52%at six months and 44 ± 14.76 percent at 12 months post-operatively (P < 0.05). The mean Kruger morphology score was 3.15 ± 3.0% pre-operatively, and 3.20 ± 2.83% at three months, 2.97 ± 2.61%at six months and 3.27 ± 2.50%at 12 months post-operatively (P > 0.05). The nucleus, acrosomal cap, mitochondrial structure and microtubules of the tail of the spermatozoa were examined under electron microscopy. The mean DNA fragmentation index (DFI%) of the spermatozoa was 20.57 ± 4.60% pre-operatively, and post-operatively at 17.27 ± 3.65% at three months, 15.5 ± 3.23% at six months and 15.3 ± 3.63% at 12 months (P < 0.001). The findings suggest that despite the increased count and motility, as well as the improved DNA fractures observed post-operatively in the spermatozoa of varicocele patients, the morphology rates remain intact.
精索静脉曲张是男性不育的主要且可通过手术修复的病因之一,它源于蔓状静脉丛中睾丸静脉的扩张和扭转。在本研究中,我们根据世界卫生组织标准,对40例年龄在15至30岁之间被诊断为精索静脉曲张的患者的精液样本进行了检查(术前以及术后3个月、6个月和12个月)。术前精子浓度平均值为4525±3483万/毫升,术后3个月平均浓度为4885±3573万/毫升,6个月时为5172±3282万/毫升,12个月时为4963±2805万/毫升(P>0.05)。术前A+B级活动精子的平均比率为35.5±14.71%,术后3个月为42.65±16.80%,6个月时为43±13.52%,12个月时为44±14.76%(P<0.05)。术前克鲁格形态学评分平均值为3.15±3.0%,术后3个月为3.20±2.83%,6个月时为2.97±2.61%,12个月时为3.27±2.50%(P>0.05)。在电子显微镜下检查了精子的细胞核、顶体帽、线粒体结构和尾部微管。术前精子的平均DNA碎片指数(DFI%)为20.57±4.60%,术后3个月为17.27±3.65%,6个月时为15.5±3.23%,12个月时为15.3±3.63%(P<0.001)。研究结果表明,尽管精索静脉曲张患者术后精子数量增加、活力增强,且DNA断裂情况有所改善,但形态学比率仍保持不变。
