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.
