With 100 subfertile varicocele patients, three months after ligation (high ligation of the left internal spermatic vein in accordance with Bernardi) had control spermiograms made. An improvement of sperm count (upgrade in a higher class according to MacLeod's partition) was found in 28% of the cases, whereas an improvement of progressive motility was found only in 13%. The percentage of patients reaching the normal value in sperm count of over 40 mill./ml increased from 23% to 39%. The increase in these patients came primarily from the class of 20--40 mill./ml. In progressive motility, there was an increase of patients reaching the standard value of over 40%, from 6 to 11. However, if sperm count and progressive motility together were evaluated in the individual patients after ligation, only 6 patients presented a normospermia, i.e. a sperm count of more than 40 mill./ml with normal progressive motility. Thus 94 of the 100 patients must be considered as subfertile three months after ligation. A significant fertility improvement through ligation of varicocele has not yet taken place.
对100例亚生育力精索静脉曲张患者，在结扎（按照贝尔纳迪方法高位结扎左精索内静脉）三个月后进行对照精液检查。28%的病例精子计数有改善（根据麦克劳德分类法提升到更高等级），而只有13%的病例精子前向运动能力有改善。精子计数达到超过4000万/毫升正常数值的患者百分比从23%增至39%。这些患者的增加主要来自2000万 - 4000万/毫升这一等级。在精子前向运动能力方面，达到超过40%标准值的患者从6例增至11例。然而，如果在结扎后对个体患者同时评估精子计数和精子前向运动能力，只有6例患者呈现正常精液，即精子计数超过4000万/毫升且精子前向运动能力正常。因此，100例患者中有94例在结扎三个月后仍被视为亚生育力。通过结扎精索静脉曲张尚未实现显著的生育力改善。
