L-carnitine-astaxanthin compound nutrients for the treatment of idiopathic oligospermia and asthenozoospermia:A multicenter clinical observation

目的:研究左旋肉碱虾青素复合营养素(梦兰康)治疗特发性少精子症及弱精子症的临床疗效。方法:293例患者纳入本研究,其中少精子症73例,弱精子症220例。患者口服左旋肉碱虾青素复合营养素1袋,每日2次,连续服用3个月,分别于治疗前及治疗后第1、2、3个月进行精液分析检测及精子DNA碎片指数(DFI)检测。结果:服用左旋肉碱虾青素复合营养素1个月后及2个月后与用药前相比,少精子症患者精子浓度[(16.74±11.15)×10^(6)/ml、(17.56±9.92)×10^(6)/ml vs(10.96±6.09)×10^(6)/ml]、精子总数[(52.98±32.07)×10^(6)、(57.67±36.98)×10^(6)vs(29.78±17.48)×10^(6)]、前向运动精子百分率[(45.3±14.03)%、(46.42±10.69)%vs(39.8±11.66)%]均显著提高(P<0.05);弱精子症患者前向运动精子百分率较用药前显著提高[(25.46±13.86)%、(27.33±12.88)%vs(19.23±8.32)%,P<0.05]。服药3个月后与用药前相比,少精子症患者精液量[(3.63±1.39)ml vs(3.07±1.47)ml]、精子浓度[(20.56±14.7)×10^(6)/ml vs(10.96±6.09)×10^(6)/ml]、精子总数[(66.35±55.91)×10^(6)vs(29.78±17.48)×10^(6)]、前向运动精子百分率[(49.24±13.45)%vs(39.8±11.66)%]、正常形态精子百分率[(2.59±0.93)%vs(1.71±1.07)%]均显著提高(P<0.05);弱精子症患者精液量[(3.85±1.59)ml vs(3.27±1.42)ml]、前向运动精子百分率[(29.11±13.58)%vs(19.23±8.32)%]、正常形态精子百分率[(2.57±1.15)%vs(2.01±1.14)%]均显著提高(P<0.05)。服药1个月后少精子症及弱精子症患者精子DFI较服药前均无明显改善,连续服药2个月及3个月后,少精子症患者精子DFI较用药前显著下降[(18.66±10.83)%、(16.48±11.46)%vs(25.87±13.76)%,P<0.05],弱精子症患者精子DFI较用药前显著下降[(19.35±11.54)%、(15.32±10.89)%vs(26.40±12.28)%,P<0.05]。结论:左旋肉碱虾青素复合营养素(梦兰康)可以显著改善少精子症及弱精子症患者精液质量。

Objective:To investigate the clinical effects of the L-carnitine-astaxanthin compound nutrients Menglankang(MLK)on idiopathic oligospermia(OS)and asthenospermia(AS).Methods:This study included 73 cases of OS and 220 cases of AS treated with MLK once a bag,bid,for 3 successive months.Before and at 1,2 and 3 months after treatment,we obtained and analyzed the semen parameters and sperm DNA fragmentation index(DFI)of the patients.Results:Compared with the baseline,the OS patients showed remarkable increases after 1 and 2 months of treatment in the semen volume([3.07±1.47]vs[3.26±1.26]and[3.30±1.28]ml),sperm concentration([10.96±6.09]vs[16.74±11.15]and[17.56±9.92]×10^(6)/ml,P<0.05),total sperm count([29.78±17.48]vs[52.98±32.07]and[57.67±36.98]×10^(6),P<0.05)and the percentages of progressively motile sperm(PMS)([39.8±11.66]%vs[45.3±14.03]%and[46.42±10.69]%,P<0.05)and morphologically normal sperm(MNS)([1.71±1.07]%vs[1.79±0.91]%and[1.84±0.96]%),and so did the AS patients in PMS([19.23±8.32]%vs[25.46±13.86]%and[27.33±12.88]%,P<0.05).After 3 months of medication,the OS patients exhibited even more significant increases in the semen volume([3.63±1.39]ml)(P<0.05),sperm concentration([20.56±14.7]×10^(6)/ml)(P<0.05),total sperm count([66.35±55.91]×10^(6))(P<0.05),PMS([49.24±13.45]%)(P<0.05)and MNS([2.59±0.93]%)(P<0.05),and so did the AS patients in the semen volume([3.27±1.42]vs[3.85±1.59]ml,P<0.05),PMS([29.11±13.58]%)(P<0.05)and NMS([2.01±1.14]%vs[2.57±1.15]%,P<0.05).In comparison with the baseline,the sperm DFI was not significantly improved at 1 month after treatment,but remarkably decreased at 2 and 3 months in the OS patients([25.87±13.76]%vs[18.66±10.83]%and[16.48±11.46]%,P<0.05)and the AS patients as well([26.40±12.28]%vs[19.35±11.54]%and[15.32±10.89]%,P<0.05).Conclusion:The L-carnitine-astaxanthin compound nutrients Menglankang can significantly improve the semen quality of the patients with idiopathic oligospermia or asthenospermia.
