【摘要】目的:通過觀察勃起功能障礙(ED)患者血清生殖激素的變化情況,探討血清生殖激素與ED之間的相關性。方法:2009年11月至2014年6月,按照當地人口統計局資料,采用經整群及年齡分層的隨機抽樣方法,調查40~80歲共計3000例有固定性伴侶的中老年男性社區居民。采用勃起功能國際指數(IIEF)評估ED及嚴重程度,化學發光法(CLIA)檢測血清總睪酮(TT)、黃體生成素(LH)、性激素結合球蛋白(SHBG),計算睪酮游離指數(TSI)、游離睪酮(FT)及生物活性睪酮(Bio-T)。結果:華東地區中老年男性人群的ED發病率為76.75%,其中輕度ED 47.56%,中度ED 10.41%,重度ED 18.78%。TSI及Bio-T隨ED患者勃起功能評分的下降而明顯降低(P<0.0001),SHBG隨著勃起功能評分下降而顯著升高(P<0.0001)。TT在不同程度的ED患者之間沒有變化規律。Pearson相關分析顯示:TSI及Bio-T與ED嚴重程度呈現顯著的負相關,SHBG與ED嚴重程度呈顯著正相關,TT與ED無明顯相關性。結論:Bio-T及SHBG對ED患者的診斷價值優于TT,TSI、Bio-T的下降及SHBG的增高應作為ED患者重要的睪酮水平指標。

【Abstract】Objectives: To observe the changes of serum reproductive hormone in erectile dysfunction (ED) patients, inn order to assess the correlation between serum reproductive hormone and ED patients. Methods: A cross-sectional randomized study of 3000 men aged from 40 to 80 years was performed in Shanghai and Zhejiang community. The erectile function (EF) was evaluated by International Index of Erectile Function 5 (IIEF-5). The serum total testosterone (TT), luteinizing hormone (LH) and sex hormone-binding globulin (SHBG) were measured by chemilum inescentenzyme immunoassay (CLIA) method, while testosterone secreting index (TSI), free testosterone (FT) and bioavailable testosterone (Bio-T) were calculated respectively. Results: The prevalence of ED was 76.75% in eastern China, of which the rates of mild, moderate and severe ED were 47.56%, 10.41% and 18.78% respectively. The concentration of TSI, Bio-T and SHBG were closely correlated with IIEF score on ED domain (P<0.0001), but this was not the case with TT. Pearson regression analysis revealed that the concentration of TSI, Bio-T and SHBG were significantly related to IIEF score, but not with TT. Conclusion: Both SHBG and Bio-T is much more effective than serum TT in diagnosis of ED. TSI/Bio-T declining and SHBG increasing plays a critical role in reflecting the testerone level of ED patients.

隨著人口老齡化進程不斷加劇,中老年男性的生殖健康問題日益突出,預計到2025年全世界50歲以上男性中勃起功能障礙(erectile dysfunction, ED)患者將超過3.22億[1]。諸多研究發現[2-4],高血壓、高血脂、心理障礙及性激素的異常等均與ED之間存在著密切聯系。然而,對基于大范圍社區男性勃起功能方面的關注相對較少。本研究調查了3000例40~80歲的有固定性伴侶社區中老年男性,同時檢測其血清生殖激素,包括:總睪酮(total testosterone, TT)、黃體生成素(luteinizing hormone, LH)、性激素結合球蛋白(sex hormone-binding globulin, SHBG),計算游離睪酮(free testosterone, FT)、睪酮游離指數(testosterone secreting index, TSI)及生物活性睪酮(bioavailable testosterone, Bio-T),分析血清生殖激素在ED患者中的影響意義。
