为了研究抑制素在控制卵泡刺激素 (FSH) 分泌中的作用,我们测量了 12 名患有血液恶性肿瘤的男性在化疗前、化疗期间和化疗后的免疫反应性抑制素 (ir-inhibin)、抑制素 B、含有抑制素的 Pro-α C、FSH、黄体生成素 (LH) 和睾酮水平。抑制素 B 水平在 1 个月内从平均 +/- SE 基线水平 273.2 +/- 32.8 pg/mL 显着下降,在 4 个月时达到最低点 52.6 +/- 15.3 pg/mL (P < 0.0001)。 FSH 水平在第一个月内从基线水平 3.9 +/- 0.6 IU/L 增加,在 4 个月时达到峰值水平 22.4 +/- 3.3 IU/L (P < 0.0001)。 FSH 和抑制素 B 呈显着负相关(r = 0.69,P < 0.0001)。含有抑制素的 Pro-αC 水平在 3 个月时显着增加(P < 0.05),并且与 FSH 显着正相关(r = 0.38,P = 0.002)。 LH 水平显着增加,但程度比 FSH 低得多,治疗开始后仅 4 个月,增加就变得明显(P < 0.03)。在整个研究过程中,ir-抑制素和睾酮水平保持不变。这些数据有力地支持了以下假设:抑制素 B 是男性体内抑制素的重要生理形式,对垂体的 FSH 分泌具有负调节作用。此外,他们表明 FSH 刺激睾丸分泌抑制素 α 亚基。
To investigate the role of inhibin in the control of follicle-stimulating hormone (FSH) secretion, we have measured levels of immunoreactive inhibin (ir-inhibin), inhibin B, Pro-alpha C containing inhibins, FSH, luteinizing hormone (LH), and testosterone in twelve men with hematological malignancies before, during, and after chemotherapy. Inhibin B levels fell significantly by 1 month from a mean +/- SE baseline level of 273.2 +/- 32.8 pg/mL, reaching a nadir of 52.6 +/- 15.3 pg/mL at 4 months (P < 0.0001). FSH levels increased within the first month from a baseline level of 3.9 +/- 0.6 IU/L, reaching a peak level of 22.4 +/- 3.3 IU/L at 4 months (P < 0.0001). FSH and inhibin B were significantly and inversely correlated (r = 0.69, P < 0.0001). Pro-alpha C containing inhibin levels increased significantly (P < 0.05) at 3 months and were significantly and positively correlated with FSH (r = 0.38, P = 0.002). LH levels increased significantly but to a much lesser extent than FSH, the increase becoming evident only 4 months after treatment commenced (P < 0.03). Levels of ir-inhibin and testosterone remained unchanged throughout the study. These data provide strong support to the hypothesis that inhibin B is the physiologically important form of inhibin in men, negatively regulating FSH secretion at the pituitary. Furthermore, they suggest that FSH stimulates inhibin alpha-subunit secretion by the testis.
