In this study, views on the acceptability of invasive reproduction tec
hniques are confronted with ethical principles. The views of 17 organi
zations are briefly discussed. Most representatives stated that a syst
ematic ethical reflection had not taken place in their organizations.
When exposed to ethical criteria, the majority were inclined to use an
imal health and welfare effects as the main guidance. Some, however, e
mphasized acknowledgement of the intrinsic value of animals and respec
t for their integrity. A comparison of these considerations with gener
ally accepted bio-ethical principles demonstrates the practical implic
ations of the principles of non-maleficence and respect for animals. I
n weighing the acceptability of human interference in animals against
the benefits of reproduction techniques, a distinction should be made
between disease control and mere economic goals. It is concluded that
in the case of the latter, almost all invasive reproduction techniques
are subject to serious ethical questioning.
