title: [Quality analysis of the primary semen samples from 512 donors].
abstract: OBJECTIVE
  To evaluate the semen quality of the donors.
  
  
  METHODS
  The semen parameters of the primary samples of 512 donors were examined following the World Health Organization (WHO) guide and computer-aided sperm analysis (CASA, product by Harmilton Thorne) system.
  
  
  RESULTS
  Of the 246 (246/512, 48%) donors with potential fertility, only 146 (146/512, 28.5%) came up to the semen standard set by the Chinese Ministry of Health, while 266 (266/512, 52%) were below the WHO reference values of semen parameters.
  
  
  CONCLUSIONS
  Repeat semen analyses may increase the success rate in screening semen donors. The semen quality of the donors suggests that it is necessary to pay more attention to male reproductive health.
