Sixty-seven Chinese male IHH patients were recruited from the Departments of Endocrinology in eight tertiary hospitals and randomly allocated into the sequential uFSH/hCG group (Group A, n = 34) or the sequential uFSH plus zinc supplementation group (Group B, n = 33). In Group A, patients received sequential uFSH (75 U, three times a week every other 3 months) and hCG (2000 U, twice a week) treatments. In Group B, patients received oral zinc supplementation (40 mg day-1) in addition to the sequential uFSH/hCG treatment given to patients in Group A. The primary outcome was the proportion of patients with a sperm concentration 〉1.0 × 106 ml-1 during the 18 months. The comparison of efficacy between Groups A and B was analyzed. Nineteen of 34 (55.9%) patients receiving sequential uFSH/hCG and 20 of 33 (60.6%) patients receiving sequential uFSH/hCG plus zinc supplementation achieved sperm concentrations ≥1.0 × 106 ml-1 by intention to treat analyses. No differences between Group A and Group B were observed as far as the efficacy of inducing spermatogenesis (P = 0.69). We concluded that the sequential uFSH/hCG plus zinc supplementation regimen had a similar efficacy to the sequential uFSH/hCG treatment alone. The additional improvement of 40 mg day-1 oral zinc supplementation on spermatogenesis and masculinization in male IHH patients is very subtle.展开更多
目的观察对单一性低促性腺激素型性腺功能减退症(IHH)患者脂联素与睾酮水平的关系。方法通过分析临床资料及激素测定、促性腺激素释放激素激发试验确诊IHH,检测23例IHH患者和15名正常男性血清脂联素和睾酮水平。结果与体重指数、腰臀比...目的观察对单一性低促性腺激素型性腺功能减退症(IHH)患者脂联素与睾酮水平的关系。方法通过分析临床资料及激素测定、促性腺激素释放激素激发试验确诊IHH,检测23例IHH患者和15名正常男性血清脂联素和睾酮水平。结果与体重指数、腰臀比以及血压均匹配的正常对照组相比,IHH患者睾酮水平显著低于正常[(0.23±0.18 vs 4.20±1.90)μg/L,P<0.01],其脂联素水平显著升高[(11.3±1.8 vs 8.7±1.2)mg/L,P<0.01]。对两组进行相关分析显示,血清脂联素水平与睾酮水平呈负相关(r=-0.570,P<0.01)。结论IHH低睾酮水平人群中脂联素水平显著升高,提示脂联素与睾酮水平之间存在密切关系。展开更多
