Fewer medical students are open to body donation after dissecting human cadavers

Introduction: Cadaver dissection has long been hailed as a vital component of medical education. Although most physicians acknowledge positive impacts of cadaver dissection on their learning, they are less likely to will their bodies for anatomical dissection than the general public. This study aims to determine whether the proportion of medical students open to willed body donation changes after completing cadaver dissection.

Methods: We conducted a longitudinal study surveying 323 medical students across three cohorts before and after anatomical dissection of human cadavers. Through the survey, students indicated whether they would will their body for anatomical dissection. Additionally, students responded to items regarding the rationale underlying their decision, demographics and perceived effects of anatomical dissection on medical education.

Results: The proportion of students who expressed openness to willed body donation decreased by 25% after cadaver dissection. Of the 171 students who initially stated they would will their body, 61 (35%) changed their response after completing cadaver dissection. Those who cited religion as a motivating factor were less likely to show openness to body donation, whereas those who cited ethical factors were more likely.

Conclusions: This study documents a substantial decrease in the proportion of students open to willed body donation after completion of cadaver dissection. Despite this, students almost universally report educational benefits of cadaver dissection. This raises interesting questions regarding the emotional impact of cadaver dissection and the ethical implications of willed body donation.
