Dr. R. Peter Elsden is a veterinarian with a Master's Degree in reproductive physiology. He was in mixed practice for nine years, worked for a large cattle company for two years and was an associate professor at Colorado State University for nine years (until December 31, 1984). Presently, he offers his services through his embryo transfer consulting business.

While at Colorado State University, Dr. Elsden was Associate Professor on the staff of the Veterinary Teaching Hospital in the Department of Physiology and Biophysics, teaching reproductive physiology and diseases to veterinary students. He was also Director of the Animal Reproduction Laboratory's Embryo Transfer Unit, which included commercial, teaching and research interests.

Dr. Elsden developed techniques to nonsurgically recover and transfer embryos to amplify the reproductive potential of selected donors of high genetic value and to circumvent some kinds of infertility. In addition, his group developed a practical technique of microsurgically dividing bovine and equine embryos to produce identical twins which are useful for research and beneficial to the cattle and equine industries. Current interests are in developing in vitro fertilization techniques, sexing embryos and improving embryo freezing technology.

Dr. Elsden has lectured overseas on many occasions in his field and organized embryo transfer programs in many countries. Over the last several years he has given numerous courses on the techniques of embryo transfer to farmers, ranchers, and veterinarians. Dr. Elsden consults for the United States Department of Agriculture, The Food and Agriculture Organization of The United Nations, Winthrop International (Rockefeller), several foreign governments, and many embryo transfer groups. He has over fifty scientific articles in referred journals and numerous publications in popular cattle magazines. He is a past President of the International Embryo Transfer Association. He was nominated a member of the Spanish Academy of Sciences for Veterinarians in 1984 and was awarded the Oliver P. Pennock Distinguished Service Award for meritorious teaching and research at Colorado State University in 1985.
