[Luobufukebiri Pills improve semen quality and seminal plasma-related biochemical indexes in patients with asthenospermia].

OBJECTIVE: To investigate the clinical effect of Luobufukebiri Pills (LP) on asthenospermia and its action mechanism. METHODS: A total of 206 patients with asthenospermia in Henan Provincial Hospital of Traditional Chinese Medicine from March 2018 to December 2018 were randomly assigned to receive oral LP (the experimental group, n = 103) bid 10 pills each time or vitamin E soft capsules (the control group, n = 103) bid 100 mg each time for a course of 12 weeks. We compared the semen volume, sperm concentration, sperm motility, levels of α-glucosidase (α-Glu), fructose (Fru), malondialdehyde (MDA) and superoxide dismutase (SOD) in the seminal plasma, and the number of pregnancies between the two groups of patients before and after treatment. RESULTS: All the patients finished the experiment except 1 in the control group due to personal reasons. After 12 weeks of medication, the patients in the experimental group showed significant increases over the baseline in sperm concentration (ï¼»36.27 ± 11.05ï¼½ vs ï¼»25.96 ± 8.63ï¼½ ×106/ml, P < 0.05), grade a sperm (ï¼»16.92 ± 5.72ï¼½% vs ï¼»9.34 ± 3.18ï¼½%, P < 0.05), grade a+b sperm (ï¼»36.08 ± 6.84ï¼½% vs ï¼»19.88 ± 4.65ï¼½%, P < 0.05), total sperm motility (ï¼»50.37 ± 10.38ï¼½% vs ï¼»24.62 ± 6.12ï¼½%, P < 0.05), and the levels of α-Glu (ï¼»46.94 ± 9.16ï¼½ vs ï¼»32.25 ± 8.30ï¼½ U/ml, P < 0.05), Fru (ï¼»28.08 ± 5.72ï¼½ vs ï¼»16.38 ± 4.62ï¼½ µmol/ml, P < 0.05) and SOD (ï¼»182.28 ± 18.44ï¼½ vs ï¼»100.37 ± 10.22ï¼½ U/ml, P < 0.05), but a decrease in the content of seminal plasma MDA (ï¼»10.37 ± 2.93ï¼½ vs ï¼»15.62 ± 4.68ï¼½ nmol/ml, P < 0.05). Increases were also observed in the control group over the baseline in grade a sperm (ï¼»12.40 ± 6.33ï¼½% vs ï¼»9.26 ± 2.94ï¼½%, P < 0.05), grade a+b sperm (ï¼»25.42 ± 5.24ï¼½% vs ï¼»19.43 ± 4.17ï¼½%, P < 0.05), total sperm motility (ï¼»40.22 ± 9.72ï¼½% vs ï¼»23.99 ± 5.77ï¼½%, P < 0.05), and levels of α-Glu (ï¼»40.31 ± 8.22ï¼½ vs ï¼»31.06 ± 7.51ï¼½ U/ml, P < 0.05) and SOD (ï¼»139.71 ± 14.08ï¼½ vs ï¼»102.11 ± 9.24ï¼½ U/ml, P < 0.05), but a decrease in the content of seminal plasma MDA (ï¼»12.72 ± 3.11ï¼½ vs ï¼»15.62 ± 4.68ï¼½ nmol/ml, P < 0.05). The total clinical effectiveness rate was remarkably higher in the experimental than in the control group (87.38% vs 58.82%, P < 0.05). CONCLUSIONS: Luobufukebiri Pills are safe and effective for the treatment of asthenospermia, which may be attributed to their ability of improving oxidative stress damage.
