[Compound amino acid combined with vitamin E for idiopathic asthenospermia].

Objective: To study the therapeutic efficacy of compound amino acid combined with vitamin E in the treatment of idiopathic asthenospermia.

Methods: This study included 120 cases of idiopathic asthenospermia treated in the Outpatient Department of our hospital between February 2014 and January 2015. We randomized the patients into a treatment group( n = 70,aged23- 43 [mean 32. 5] years) and a control group( n = 50,aged 23- 44 [mean 31. 7] years),the former treated with compound amino acid plus vitamin E while the latter with vitamin E only. After 90 days of medication, we evaluated the therapeutic effects by comparing the total sperm motility( progressive motility + non-progressive motility, PR + NP),the percentage of progressively motile sperm( PR),and the pregnancy rate between the two groups.

Results: Before treatment, PR + NP and PR were(26. 24 ± 6. 56) %and(24. 65 ± 6. 43) % in the treatment group and(15. 13 ± 5. 68) % and(14. 73 ± 6. 16) in the control, with no statistically significant differences between the two groups( P > 0. 05). After 90 days of medication, PR + NP and PR were( 49. 63 ± 9. 78) % and(33. 33 ± 5. 64)% in the former and(37. 67 ± 7. 98)% and(27. 23 ± 6. 46)% in the latter, remarkably increased in both groups as compared with the baseline( P < 0. 05),but significantly more in the treatment than in the control group( P < 0. 05). Four pregnancies(5. 71%) were achieved in the former group but only 1(2. 00%) in the latter. The total rate of effectiveness was markedly higher in the treatment group than in the control(74. 28% vs 44. 00%,P < 0. 05). No adverse reactions were observed in either group.

Conclusion: Compound amino acid combined with vitamin E can safely and effectively improve sperm motility in idiopathic asthenospermia patients.
