title: Analysis of the Screening Results for 3,564 Student Sperm Donors in Hubei Province, China.
abstract: OBJECTIVE
  To determine the reasons for the elimination of student sperm donors after semen analysis, physical examination, and laboratory tests in the Hubei Provincial Human Sperm Bank. Understanding the status of student sperm donors can provide a valid reference for the screening work of sperm banks.
  
  
  METHODS
  The screening data from 3,564 student sperm donors in Hubei Provincial Human Sperm Bank from January 1, 2010-April 30, 2013, were retrospectively analyzed.
  
  
  RESULTS
  A total of 733 students (20.57%) qualified for semen analysis in the human sperm bank, whereas 602 students (16.89%) completed the sperm donation procedure. The main reasons for elimination were as follows: unqualified semen parameters (2,748 cases), failed semen extraction (83 cases), sexually transmitted diseases (44 cases), hereditary or chromosomal disorders (44 cases), and hepatitis B infection (25 cases). Education level and temperature/climate possibly affect semen quality.
  
  
  CONCLUSIONS
  Unqualified semen parameters were the main reason for elimination among student sperm donors. Human sperm banks should promote reproductive health knowledge and information on improving semen quality among students when promoting sperm donation.
