RESUMEN
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 (ï¼»3.07 ± 1.47ï¼½ vs ï¼»3.26 ± 1.26ï¼½ and ï¼»3.30 ± 1.28ï¼½ ml), sperm concentration (ï¼»10.96 ± 6.09ï¼½ vs ï¼»16.74 ± 11.15ï¼½ and ï¼»17.56 ± 9.92ï¼½ ×106/ml, P < 0.05), total sperm count (ï¼»29.78 ± 17.48ï¼½ vs ï¼»52.98 ± 32.07ï¼½ and ï¼»57.67 ± 36.98ï¼½ ×106, P < 0.05) and the percentages of progressively motile sperm (PMS) (ï¼»39.8 ± 11.66ï¼½% vs ï¼»45.3 ± 14.03ï¼½% and ï¼»46.42 ± 10.69ï¼½%, P < 0.05) and morphologically normal sperm (MNS) (ï¼»1.71 ± 1.07ï¼½% vs ï¼»1.79 ± 0.91ï¼½% and ï¼»1.84 ± 0.96ï¼½%), and so did the AS patients in PMS (ï¼»19.23 ± 8.32ï¼½% vs ï¼»25.46 ± 13.86ï¼½% and ï¼»27.33 ± 12.88ï¼½%, P < 0.05). After 3 months of medication, the OS patients exhibited even more significant increases in the semen volume (ï¼»3.63 ± 1.39ï¼½ ml) (P < 0.05), sperm concentration (ï¼»20.56 ± 14.7ï¼½ ×106/ml) (P < 0.05), total sperm count (ï¼»66.35 ± 55.91ï¼½ ×106) (P < 0.05), PMS (ï¼»49.24 ± 13.45ï¼½%) (P < 0.05) and MNS (ï¼»2.59 ± 0.93ï¼½%) (P < 0.05), and so did the AS patients in the semen volume (ï¼»3.27 ± 1.42ï¼½ vs ï¼»3.85 ± 1.59ï¼½ ml, P < 0.05), PMS (ï¼»29.11 ± 13.58ï¼½%) (P < 0.05) and NMS (ï¼»2.01 ± 1.14ï¼½% vs ï¼»2.57 ± 1.15ï¼½%, 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 (ï¼»25.87 ± 13.76ï¼½% vs ï¼»18.66 ± 10.83ï¼½% and ï¼»16.48 ± 11.46ï¼½%, P < 0.05) and the AS patients as well (ï¼»26.40 ± 12.28ï¼½% vs ï¼»19.35 ± 11.54ï¼½% and ï¼»15.32 ± 10.89ï¼½%, P < 0.05). CONCLUSIONS: The L-carnitine-astaxanthin compound nutrients Menglankang can significantly improve the semen quality of the patients with idiopathic oligospermia or asthenospermia.

OBJECTIVE: To explore the correlation of the sperm DNA fragmentation index (DFI) with age and other semen parameters in infertile men and its influence on the outcomes of in vitro fertilization and embryo transplantation (IVF-ET). METHODS: Semen samples were obtained from 6 162 infertile males in our hospital between July 2017 and December 2018. Sperm concentration, the percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS) and sperm DFI were determined by computer-assisted semen analysis, modified Papanicolaou staining and sperm chromatin structure assay, respectively. According to the sperm DFI, the samples were divided into three groups: DFI≤15%, 15%
