title: [Effect of modified tianxiong powder in treating oligospermia and asthenospermia].
abstract: OBJECTIVE
  To investigate the clinical efficacy and safety of modified Tianxiong Powder (MTP) in treating oligospermia and asthenospermia.
  
  
  METHODS
  Eighty patients were equally randomized into two groups, the treated group administered with MTP, and the controlled group administered with Wuzi Yanzong Pill (WYP), all for 3 months. The comprehensive efficacy was observed; and parameters of patients' semen and figure of sperm were analyzed before and after treatment.
  
  
  RESULTS
  The observation was completed in 70 patients. The total effective rate and markedly effective rate were 91.43% and 65.71%, respectively in the treated group, 85.71% and 54.29%, respectively in the control group, the pregnancy rate in their wives was 8.57% and 5.71%, respectively. Comparisons showed no statistical significance between groups (P > 0.05). Significant elevated perm count in semen and more active sperms with significantly better spermic figure, were found in both groups. However, the improvements in the treatment group were superior to those in the control group (P < 0.05 or P < 0.01).
  
  
  CONCLUSIONS
  MTP shows good efficacy and high safety in treating oligospermia and asthenospermia, and it could improve the spermic count, motility and figure, and reduce the head deformity rate.
