IETS Publications

Reproduction, Fertility and Development is an international journal for the publication of original and significant contributions to the field of reproductive biology in vertebrate animals, including humans, livestock and wildlife (as well as pest animals). Work on wildlife must not simply extend familiar biology to a new species – it must show how the species studied adds new perspectives to our general understanding of reproductive biology.

Position Statement of the IETS on Genome Engineering

The International Embryo Technology Society (IETS) supports genome engineering, including gene editing, as it provides invaluable advances in basic research, animal welfare, sustainable agriculture and safer food production, and human medicine. Genetically engineered products are highly regulated and must pass rigorous safety reviews for humans, agriculture, and the environment. The International Embryo Technology Society will continue to (1) support its members to lead and conduct genome engineering research, (2) provide expertise to regulatory agencies, and (3) engage with the general public for science education.
