Dr. Fernando L. Riera is a leading specialist in equine reproductive medicine and biotechnology. He is the Director at Doña Pilar Embriones SRL, a prominent equine reproduction and biotechnology centre located in the Buenos Aires Province, Argentina.

His work combines clinical reproductive practice with advanced biotechnologies for horses — serving clients throughout Argentina and internationally.

As a technical and scientific leader at Doña Pilar, Dr. Riera has directed and contributed to high-impact reproductive programs and pioneering techniques in equine breeding. He has presented impressive commercial data from Doña Pilar’s embryo transfer activities, including large-scale annual procedures involving thousands of donor mares and recipient mares, optimizing results, procedures, logistics and cost-effectiveness for clients. 
Dr. Riera has presented results related to embryo biopsy and vitrification (freezing) of equine embryos — advanced techniques essential for genetic evaluation and long-term preservation.
He has shared methods and outcomes for oocyte transfer — a technique that allows oocytes (egg cells) from infertile or valuable donor mares to be transferred and carried by surrogate recipients, leading to successful pregnancies.
Dr. Riera has served as a speaker and workshop coordinator at major scientific meetings on equine reproductive technology, demonstrating practical applications of assisted reproductive techniques and facilitating knowledge exchange within the veterinary and equine science community.
He has co-authored research on in vitro embryo development and reproductive technologies with international collaborators, contributing to the scientific understanding of embryo culture and developmental biology in horses.
Beyond clinical work, Dr. Riera also participates as an instructor in academic programs and trainings on equine reproductive biotechnologies, helping educate veterinarians and specialists in current best practices.
