We are profoundly saddened to announce the passing of Professor Francis Fiéni, who passed away yesterday. Prof. Fiéni devoted many years of dedicated service to the Veterinary School of Nantes, where his tireless commitment and hard work were greatly valued by his colleagues and students. He was a distinguished member of Pathology and Biotechnologies of Reproduction teaching Unit and founded and managed the Sanitary Security of Reproduction Biotechnology research team at Oniris, the Nantes – National College of Veterinary Medicine, Food Science and Engineering.

Prof. Fiéni was a pillar of the Veterinary School of Nantes, serving as a professor at Oniris – Nantes – National College of Veterinary Medicine, Food Science, and Engineering. He was a pioneer in the use of PGF2a and aglepristone in canine females in case of abortion, to treat pyometra and induce parturition.  His expertise lay also in reproductive biotechnology, particularly focusing firstly on freezing of caprine embryos and then on the sanitary security of embryo transfer. His groundbreaking research addressed critical challenges, such as the prevention of disease transmission through reproductive technologies, setting new standards for safety and innovation in the field.

As an educator, Prof. Fiéni was deeply committed to his students and colleagues. His passion for teaching and mentoring inspired generations of veterinarians and researchers, many of whom continue to carry forward his teachings and values. Beyond his academic achievements, he was known for his kindness, humility and unwavering dedication to the betterment of veterinary medicine.

The European Veterinary Society for Small Animal Reproduction (EVSSAR) joins his family, friends and colleagues in mourning this tremendous loss. His passing is not only a loss to the academic world but to all who admired his intellect, generosity and pioneering spirit.

We extend our heartfelt condolences to his family and loved ones during this difficult time. Our thoughts are with them as we grieve the loss of an extraordinary human being whose impact will be felt for generations to come.

May his legacy continue to inspire, and may he rest in peace.
