title: [Qilin pills for oligoasthenospermia: a multi-centered clinical trial].
abstract: OBJECTIVE
  To observe the efficacy of Qilin Pills in the treatment of oligoasthenospermia.
  
  
  METHODS
  We conducted a multi-centered open controlled clinical trial by including 220 oligoasthenospermia patients in a trial group and another 110 as controls. The patients in the trial group were treated with Qilin Pills at the dose of 6 g tid, and the controls given Wuziyanzong Pills at 6 g bid, both for a course of 12 weeks. Then we evaluated the clinical effects of Qilin Pills with sperm concentration, the numbers of grade a and grade a + b sperm, and sperm motility as the primary, and the pregnancy rate of the patients'spouses as the secondary therapeutic indexes.
  
  
  RESULTS
  A total of 310 patients accomplished the clinical trial, 208 in the trial and 102 in the control group. Compared with the baseline, significant improvement was observed in the semen parameters after 4, 8 and 12 weeks of treatment in both the trial and control groups except sperm density and the number of grade a sperm in the control after 4 weeks (P < 0.01), and the improvement was even more significant in all the semen parameters at the same time points in the trial than in the control group (P < 0.01).
  
  
  CONCLUSIONS
  Qilin Pills can evidently improve the seminal quality of oligoasthenospermia patients with no obvious adverse events.
