年龄和年级对精索静脉曲张患者手术的影响。 (注:这里原文中的“grade”翻译为“年级”在医学语境不太准确,可能是“分级”等意思,但按要求不做修改和解释)

Abstract

OBJECTIVES

To assess the seminal characteristics, hormonal levels, and pathologic findings in patients of various age groups with varicocele before and after ligation to establish the presence of an aging effect in patients with varicocele on those characteristics.

METHODS

The records were retrospectively evaluated for 70 infertile patients with azoospermia or oligospermia who underwent microsurgical left inguinal varicocele ligation. The mean +/- SD patient age was 33.9 +/- 5.5 years. Left varicocele was detected in 70 patients. We divided our patients into three groups according to age: group 1, 20 to 29 years old (n = 17); group 2, 30 to 39 years old (n = 41); and group 3, older than 40 years (n = 12).

RESULTS

Before ligation, no significant differences were seen among the three groups in luteinizing hormonal level, prolactin level, estradiol level, right testicular volume, semen volume, and sperm concentration and sperm motility. Significant differences were seen in the follicle-stimulating hormonal level, testosterone level, and left testicular volume. After ligation, even in group 3, the sperm concentration and motility increased from 6.38 +/- 5.47 to 13.07 +/- 9.05 million/mL (P = 0.042) and from 28.42% +/- 23.22% to 39.92% +/- 22.06%, respectively. No significantly greater degree of improvement in semen characteristics was observed between grade II and grade III after varicocele ligation.

CONCLUSIONS

The results of our study have shown that age is not a significant predictive factor of improvement in semen characteristics before ligation. It is reasonable to perform ligation to improve the semen characteristics in patients older than 40 years old.

摘要

目的

评估不同年龄组精索静脉曲张患者结扎前后的精液特征、激素水平及病理结果,以确定精索静脉曲张患者这些特征是否存在年龄相关影响。

方法

回顾性评估70例接受显微外科左侧腹股沟精索静脉曲张结扎术的无精子症或少精子症不育患者的记录。患者平均年龄为33.9±5.5岁。70例患者均检测出左侧精索静脉曲张。我们根据年龄将患者分为三组:第1组,20至29岁(n = 17);第2组,30至39岁(n = 41);第3组,40岁以上(n = 12)。

结果

结扎前,三组在黄体生成素水平、催乳素水平、雌二醇水平、右侧睾丸体积、精液量、精子浓度和精子活力方面无显著差异。在卵泡刺激素水平、睾酮水平和左侧睾丸体积方面存在显著差异。结扎后,即使在第3组,精子浓度和活力也分别从6.38±5.47增加至13.07±9.05百万/mL(P = 0.042),从28.42%±23.22%增加至39.92%±22.06%。精索静脉曲张结扎术后,II级和III级之间精液特征改善程度无显著差异。

结论

我们的研究结果表明,年龄不是结扎前精液特征改善的显著预测因素。对40岁以上患者进行结扎以改善精液特征是合理的。
