本文收集了目前所发表的临床试验结果,全面系统地综述了左旋肉碱+乙酰左旋肉碱对男性不育的治疗作用.所引用的数据来自对医学数据库的相关临床试验结果,及9个随机对照的临床试验(RCTs)结果.所有数据的可靠性经皆经过了随机性和双盲行的分析验证.经统计学的元分析和与空白对照相比发现,联合服用左旋肉碱+乙酰左旋肉碱可显着提高怀孕率(p<,0.001),显着提高精子活动力(p等于0.04),显着提高前向精子活动力(p等于0.04)及显着降低异常形态精子数量(p<,0.00001).但对精子的数量和浓度的影响不大.结论:联合服用左旋肉碱+乙酰左旋肉碱可显着提高男性不育患者的怀孕率和精子的活动力.同时,复合左旋肉碱对男性不育患者更精确的作用值得一步的研究.
