"We must use embryo technology to make advances in genetic gain that will make livestock production more efficient and thus more sustainable. We have to produce more with less, and using embryo technology is the only way to do that on a timeline that will make a difference to the planet."

- Rebecca Krisher, President, IETS

"Embryo technologies improve the quality of animals, which improves the health and productivity of the domestic animal industry. This is good for food security and [reduces our] environmental footprint. Secondly the research supported and shared at IETS on wild or rare species conservation is a direct support for better biodiversity."

- Marc-André Sirard, Vice President, IETS

"Virtually every major zoo research program in the United States and many others around the world are represented in IETS membership, indicating the Society’s vital role in promoting and sustaining biodiversity research. IETS members are valued advisors, collaborators, and co-authors, promoting and advancing critical work in biodiversity."

- Barbara Durrant, Former IETS Treasurer

"IETS joins the latest technologies in embryo production […] to facilitate and make it affordable to make advancements in animal species, which aids all the crucial challenges that we face today."

- Daniel Angel Velez, Trainee Member

"IETS has always had a huge impact on embryo science and technology, from the early days with the development of embryo transfer and in vitro fertilization to the future of gene editing. Embryo technologies developed by IETS members have allowed more rapid selection and improvement of production traits and elimination of detrimental genes."

- Carol L. Keefer, Past President, IETS

"[IETS offers me] the chance to meet and talk to many friends and colleagues and catch up to what has happened in the past year, to have the ‘backstage’ of what is really happening in the field of animal embryo technology."

- Cesare Galli, Past President, IETS

"IETS members continue to carry out cutting-edge research that makes significant contributions to improving reproductive efficiency through improved knowledge (regulation of embryo development, pregnancy establishment, genetics, management), leading to improvements in production efficiency, which is essential with a growing world population and associated growing demand for safe, high-quality food. Also, members are leading the way in terms of conservation of wild and endangered species and breeds."

- Patrick Lonergan, Past President, IETS

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.
