研究目的: |
总目的:本研究旨在通过一项随机、双盲、安慰剂对照试验,评估在标准降糖治疗基础上,加用桑枝总生物碱(SZ-A)对T2DM合并少弱精子症患者精液质量及相关生理指标的改善作用与安全性。 主要目的:评价SZ-A联合标准治疗相较于安慰剂联合标准治疗,对患者精子浓度的改善效果。 次要目的: 评估SZ-A对其他精液参数(精子总数、前向运动精子比例、正常形态率)的影响。 评估SZ-A对患者糖代谢指标(如HbA1c、HOMA-IR)的额外调节作用。 探索SZ-A对患者生殖激素水平(FSH、LH、总睾酮、抑制素B等)的影响。 初步探索SZ-A对患者氧化应激(MDA、TAC)及炎症状态(IL-6)的调节作用。 评估SZ-A联合治疗方案在此类患者中的安全性。 |

Objectives of Study: |
Overall Objective: This study aims to evaluate, through a randomized, double-blind, placebo-controlled trial, the efficacy and safety of adding Sangzhi Alkaloids (SZ-A) to standard glucose-lowering therapy in improving semen quality and related physiological parameters in patients with type 2 diabetes mellitus (T2DM) and oligoasthenospermia. Primary Objective: To evaluate the efficacy of SZ-A combined with standard therapy compared to placebo combined with standard therapy in improving sperm concentration in patients. Secondary Objectives: To assess the effect of SZ-A on other semen parameters (total sperm count, progressive motility rate, normal morphology rate). To evaluate the additional regulatory effect of SZ-A on patients' glucose metabolism indicators (e.g., HbA1c, HOMA-IR). To explore the impact of SZ-A on patients' reproductive hormone levels (FSH, LH, total testosterone, inhibin B, etc.). To preliminarily explore the modulatory effects of SZ-A on patients' oxidative stress (MDA, TAC) and inflammatory status (IL-6). To assess the safety of the SZ-A combination therapy regimen in this patient population. |

Severe Systemic Diseases: Presence of severe cardiac, hepatic, or renal insufficiency (e.g., NYHA class III–IV heart failure, ALT or AST > 3 × upper limit of normal, serum creatinine > 1.5 × upper limit of normal). 3. Diabetes-Related Complications: Occurrence of acute metabolic complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic state within the past 6 months. 4. History of Interfering Medication: Use of any medication potentially affecting sperm quality or reproductive hormones (e.g., androgens, gonadotropins, antioxidants, Chinese herbal supplements, etc.) within the past 3 months. Current or planned use of glucagon-like peptide-1 receptor agonists (e.g., semaglutide, liraglutide) for glycemic control during the study period. 5. Presence of other serious systemic diseases (e.g., active infection, malignant tumor, immune system disorders) or psychiatric disorders. 6. History of alcohol or substance abuse (defined as chronic excessive use that impacts health or social functioning). 7. Known allergy to Sangzhi alkaloids or any of its excipients. 8. Participation in any other drug or medical device clinical trials within the past 3 months. |
