In varicocele, there is venous flow of free testosterone (FT) directly from the testes into the prostate. Intraprostatic FT accelerates prostate cell production and prolongs cell lifespan, leading to the development of BPH. We show that in a large group of patients presenting with BPH, bilateral varicocele is found in all patients. A total of 901 patients being treated for BPH were evaluated for varicocele. Three diagnostic methods were used as follows: physical examination, colour flow Doppler ultrasound and contact liquid crystal thermography. Bilateral varicocele was found in all 901 patients by at least one of three diagnostic methods. Of those subsequently treated by sclerotherapy, prostate volume was reduced in more than 80%, with prostate symptoms improved. A straightforward pathophysiologic connection exists between bilateral varicocele and BPH. The failure of the one-way valves in the internal spermatic veins leads to a cascade of phenomena that are unique to humans, a result of upright posture. The prostate is subjected to an anomalous venous supply of undiluted, bioactive free testosterone. FT, the obligate control hormone of prostate cells, reaches the prostate directly via the venous drainage system in high concentrations, accelerating the rate of cell production and lengthening cell lifespan, resulting in BPH.
在精索静脉曲张中,游离睾酮(FT)可直接从睾丸经静脉流入前列腺。前列腺内的游离睾酮会加速前列腺细胞的生成并延长细胞寿命,从而导致良性前列腺增生(BPH)的发生。我们发现,在一大群患有BPH的患者中,所有患者均存在双侧精索静脉曲张。对总共901名接受BPH治疗的患者进行了精索静脉曲张评估。采用了以下三种诊断方法:体格检查、彩色多普勒超声和接触式液晶热成像。通过三种诊断方法中的至少一种,在所有901名患者中均发现了双侧精索静脉曲张。在随后接受硬化疗法治疗的患者中,超过80%的患者前列腺体积减小,前列腺症状得到改善。双侧精索静脉曲张与BPH之间存在直接的病理生理联系。精索内静脉单向瓣膜功能不全导致了一系列人类特有的现象,这是直立姿势的结果。前列腺受到未稀释的、具有生物活性的游离睾酮的异常静脉供应。游离睾酮是前列腺细胞的必需控制激素,它通过静脉引流系统以高浓度直接到达前列腺,加速细胞生成速率并延长细胞寿命,从而导致BPH。
