After creating France's first AI (artificial insemination) and ET (embryo transfer) centre for livestock in 1946, Robert Cassou founded IMV ("Instruments de Médecine Vétérinaire") in 1963. Since 1980, the group has strengthened its international presence by opening subsidiaries in the United States, India, China, Italy, the Netherlands, Scotland, Russia, Belgium, Ireland, Spain and Brazil. Beyond its global expansion, IMV's history is marked by major innovations, including consumables, solutions to automate the work of technicians in artificial insemination centres and biobanks, and the creation of new storage media and cryopreservation solutions.
