title: [Qianlie Beixi Capsules for unliquefiable semen: a multi-center clinical study].
abstract: OBJECTIVE
  To investigate the efficacy and possible action mechanism of Qianlie Beixi Capsules in the treatment of unliquefiable semen.
  
  
  METHODS
  A total of 190 patients with unliquefiable semen were treated with Qianlie Beixi Capsules for 1 or 2 courses (3 weeks per a course). The seminal changes were observed and recorded.
  
  
  RESULTS
  Of the 190 patients in the 1-course treatment arm, 99 were cured and 91 failed to respond after the first course. And the effectiveness rate was 52.1%. Of the 122 patients in the 2-course treatment arm, 81 were cured and 41 failed to respond after the second course. And the effectiveness rate was 66.4%. The efficacy of 2-course regimen was obviously better than that of 1-course regiment. In the meantime, sperm density improved in the 2-course treatment arm. Sperm motility improved slightly in the effective subjects of 1-course treatment arm. All the above results had statistically significant differences (P < 0.05).
  
  
  CONCLUSIONS
  Qianlie Beixi Capsules is both safe and effective for unliquefiable semen and may shorten the time of seminal liquefaction.
