It is generally accepted that men with clinically palpable varicocele are at high risk for a progressive decrease in fertility and testosterone levels with time. Varicocelectomy is thought to improve testicular function or at least halt the accelerated decrease in testicular function associated with varicocele. Substantial controversy exists as to whether varicocelectomy is effective in older men, possibly due to irreversible testicular damage or limited potential for recovery from varicocele induced damage.
We retrospectively reviewed the records of men who underwent microsurgical subinguinal varicocelectomy, as done by a single surgeon. Demographics, patient questionnaires, operative notes, charts, testosterone and semen analysis were reviewed. Patients were divided into 3 groups based on age at surgery, including less than 30, 30 to 39 and 40 years or greater.
A total of 272 men met study inclusion criteria. In all 3 age groups we noted similar testosterone and baseline semen analysis parameters. There were significant increases in sperm concentration and total sperm count in all age groups. When analysis was restricted to men with baseline testosterone 400 ng/dl or less, there was a mean 110, 133 and 136 ng/dl increase in 21 men who were 40 years old or older, in 30 who were 30 to 39 years old and in 21 who were younger than 30 years, respectively.
Microsurgical varicocelectomy resulted in significant increases in sperm concentration, total sperm count and testosterone in all age groups studied, including men in the fifth and sixth decades of life. Microsurgical varicocelectomy should be offered to older men for infertility and/or hypogonadism.
一般认为,临床上触诊到精索静脉曲张的男性随着时间的推移,其生育能力和睾酮水平逐渐下降的风险很高。精索静脉结扎术被认为可以改善睾丸功能,或者至少阻止与精索静脉曲张相关的睾丸功能加速下降。大量争议存在于精索静脉结扎术是否对老年男性有效,这可能是由于睾丸损伤不可逆转或精索静脉曲张引起的损伤恢复潜力有限。
我们回顾性地审查了由一位外科医生进行的显微镜下精索下静脉结扎术的男性患者的记录。回顾了人口统计学资料、患者问卷、手术记录、图表、睾酮和精液分析。根据手术时的年龄,患者分为 3 组,分别为小于 30 岁、30 至 39 岁和 40 岁或以上。
共有 272 名男性符合研究纳入标准。在所有 3 个年龄组中,我们都观察到类似的睾酮和基线精液分析参数。所有年龄组的精子浓度和总精子计数均显著增加。当分析仅限于基线睾酮水平为 400ng/dl 或以下的男性时,在年龄为 40 岁或以上的 21 名男性、30 至 39 岁的 30 名男性和小于 30 岁的 21 名男性中,分别有 110、133 和 136ng/dl 的平均增长。
显微镜下精索静脉结扎术可显著增加所有研究年龄组的精子浓度、总精子计数和睾酮水平,包括 50 岁和 60 岁的男性。对于不育和/或性腺功能减退症,应向老年男性提供显微镜下精索静脉结扎术。
