title: [Analysis of correlative factors of sterility in males undergoing routine sperm inspection by masturbation].
abstract: OBJECTIVE
  To investigate the factors influencing sterility in males undergoing routine sperm inspection by masturbation.
  
  
  METHODS
  Scales for demographic data, self-compiled infertility questionnaire, Symptom Checklist-90 (SCL-90) , and sexual life subscale of Olson Marital Quality Questionnaire (ENRICH) were assessed in 220 cases of sterility in males who had undergone sperm examination after ejaculation.
  
  
  RESULTS
  The total SCL-90 scores and the factor scores of anxiety, phobia, somatization, obsessive compulsive behavior, interpersonal-sensitivity, hostility, and depression were significantly higher than the norm (P<0.05). The total SCL-90 score of 69 males was higher than 160, implying that 31.36% of the sterile males had negative emotions. The total score was related to wife's attitude, semen collecting room, ejaculation situation, and the general state of sexual life. The ejaculation situation was subjected to a multivariate linear regression model.
  
  
  CONCLUSIONS
  About 1/3 of males with sterility problems undergoing routine semen examination by masturbation have negative emotions such as anxiety, phobia, somatization, and interpersonal sensitivities. The defective ejaculation may be the influential factor at the stage.
