Results from our laboratory have revealed that seminal plasma concentration of acid phosphatase, maltase, prolactin, citric acid, zinc and magnesium which are the secretory products of the prostate gland, decreased significantly in vasectomized men compared to those in controls namely normal fertile men. Further, it was observed that the decrease in prostatic function was not related to the time since vasectomy. Considering these two facts together, we propose that vasectomy may lead to decrease in the incidence of prostatic tumors - a disease that claims nearly 22,000 lives each year in the United States alone.
我们实验室的研究结果显示，前列腺分泌的酸性磷酸酶、麦芽糖酶、催乳素、柠檬酸、锌和镁的精浆浓度，与对照组即正常生育男性相比，输精管结扎男性显著降低。此外，观察到前列腺功能的下降与输精管结扎后的时间无关。综合考虑这两个事实，我们认为输精管结扎可能会导致前列腺肿瘤发病率降低——仅在美国，这种疾病每年就夺去近22000人的生命。
