title: [Clinical efficacy of Yangjing Decoction on idiopathic asthenozoospermia].
abstract: OBJECTIVE
  To evaluate the clinical effect of the Chinese medicine Yangjing Decoction on idiopathic asthenospermia.
  
  
  METHODS
  This study included 62 patients with idiopathic asthenospermia diagnosed with the computer-assisted semen analysis system and other methods based on the WHO guidelines. The patients were equally randomized to a trial and a control group, the former treated with Yangjing Decoction at the dose of 400 ml bid, and the latter with Yougui Capsules tid, both for a course of 6 months. Then we analyzed the changes in sperm concentration and percentage of grade a + b sperm in the patients, as well as the pregnancy in their wives.
  
  
  RESULTS
  Compared with the controls, the patients of the trial group showed a significantly elevated percentage of grade a + b sperm after 6 months medication (P < 0.01), though no statistically significant differences were observed in sperm concentration (P > 0.05). The total rate of effectiveness was 87.09% and 7 pregnancies were achieved in the trial group, as compared with 66.74% and 3 pregnancies in the controls (P < 0.05).
  
  
  CONCLUSIONS
  Yangjing Decoction can significantly improve sperm vitality, and has a desirable effect on idiopathic asthenospermia.
