29. April 2020Castration of adult male C57BL/6JRj mice allows for resocialization and social housing of previously single-housed males: a harm-benefit analysis

Procedures on animals causing pain, suffering, and distress raise difficult ethical and moral issues. Therefore, in a harm-benefit analysis, the benefits of the outcome are weighed against the harm the animal will experience (Grimm 2014, Grimm et al. 2019). This is required by law for animal experimentation (Directive 2010/63/EU), but is also applicable to housing, husbandry, and routine procedures diminishing the well-being of the animal.
