From: Motivational stimuli to donate sperm among non-donor students
Positive and negative stimuli towards sperm donation. a Positive stimuli comparison (q. 18-22). Participants ranking using 1-5 Likert scale was summarized as mean for each stimulation. Positive stimulus comparison by Wilcoxon test resulted with significant grading differences between all stimuli (p<0.05) except similar ranking to “comprehensive medical evaluation for free” and “personal acquaintance with fertility patients”. Financial reward had the highest rank followed by willingness to help others. Passing genes to future generation was ranked as lowest. b Negative stimuli comparison (q. 23-27). Participants ranking using 1-5 Likert scale was summarized as mean for each stimulation. Negative stimulus comparison by Wilcoxon test resulted with significant grading differences between most stimuli (p<0.05) Among aversive stimuli, fear of losing anonymity and future regret (4 and 3.8 on 1-5 Liker scale, respectively) were significantly highest ranked compared to all other statements. Possible negative impact on future relationship had slightly lower rank (3.7)
