title: [Clinical efficacy of Yougui capsules and Wuziyanzong pills on oligoasthenospermia].
abstract: OBJECTIVE
  To investigate the clinical effects of the Chinese traditional medicine Yougui Capsules and Wuziyanzong Pills on sperm viability and motility in patients with oligoasthenospermia.
  
  
  METHODS
  A total of 80 infertile men oligoasthenospermia were equally randomized into a trial and a control group, the former treated with Yougui Capsules at 1.68 g tid, while the latter with Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks. The sperm viability and motility of the patients were detected and compared before and after medication.
  
  
  RESULTS
  After 12 weeks of medication, the sperm viability and percentages of grade a and grade a + b sperm were (65.7 +/- 13.1), (22.5 +/- 9.1) and (47.6 +/- 15.8)% in the trial group, significantly higher than (38.1 +/- 11.1), (13.2 +/- 6.8) and (24.1 +/- 10.9)% in the control (P<0.05). What's more, the above three parameters of the two groups were also significantly higher than those before medication, which were (31.9 +/- 16.9), (8.2% +/- 3.7) and (15.7 +/- 13.9)% in the former and (31.7 +/- 17.0), (7.9 +/- 4.5) and (16.9 +/- 13.6)% in the latter (P<0.05).
  
  
  CONCLUSIONS
  Both Yougui Capsules and Wuziyanzong Pills can improve sperm viability and motility in patients with oligoasthenospermia, and the former is even more efficacious than the latter.
