Dr. James Raeside Honoured with Lifetime Achievement Award in Equine ReproductionJuly 2018
Story: Nicole Weidner
Dr. Raeside has had a long and illustrious career, adding quantity and quality to the Equine Reproduction literature. A quick search will find his name attached to publications on topics ranging from estrogen metabolism in the equine embryo, to stallion fertility, and non-invasive assessments of pregnancy in the feral horses of Sable Island. Dr. Raeside has contributed to several important projects that have been funded in part by Equine Guelph, including studies looking at early pregnancy failure in mares and steroid metabolites in equine embryos. Dr. Raeside cites 2 main discoveries as his favourite career highlights. The first he says, “was finding estrone sulfate, a biologically inactive form of estrogen, in stallion testes—to answer the conundrum of high masculinity in the face of exceedingly high estrogens in stallion urine.” He names the second as “finding dehydroepiandrosterone in horse fetal gonads--leading to the discovery of the feto-placental unit as the source of high amounts of estrogens in the urine of pregnant mares.”
