[Shugan Yiyang Capsules for the treatment of asthenospermia: A clinical study].

Objective: To observe the clinical efficacy of Shugan Yiyang Capsules in the treatment of asthenospermia and its action mechanisms. Methods: We randomly assigned 135 asthenospermia patients to groups A( n = 47),B( n = 45),and C( n =43) to be treated with Shugan Yiyang Capsules,oral levocarnitine,or combination of the two. We observed sperm quality and the level of α-glucosidase in the seminal plasma before and after medication. Results: The total effectiveness rate was 70. 21% in group A( markedly effective in 16 cases and effective in 17),68. 89% in group B( markedly effective in 15 cases and effective in 16),and83. 72% in group C( markedly effective in 16 cases and effective in 20),significantly higher in C than in A and B( P 0. 05). Both sperm quality and the level of α-glucosidase in the seminal plasma were improved in the three groups of patients,most obviously in group C. Conclusion: Shugan Yiyang Capsules can be used for the treatment of asthenospermia,and its effect can be enhanced in combination with oral levocarnitine.
