Transient post breeding endometritis is a normal physiological reaction in the mare, as it is believed that an inflammatory response is necessary for the effective removal of contaminating bacteria and excess spermatozoa introduced into the uterus. While most mares can clear endometritis within a reasonable amount of time, persistent endometritis caused by either bacteria or spermatozoa can threaten the success of a pregnancy. A subpopulation of mares is susceptible to persistent endometritis, and these mares are a concern in equine reproductive medicine. Research has identified several factors that contribute to susceptibility; however, the exact mechanisms of the progression of the disease are still being elucidated. Current research focuses on endometrial gene expression during endometritis in an attempt to understand the timing of specific inflammatory processes involved with the development of susceptibility to persistent endometritis. With an increased understanding of the mechanisms involved with the disease, current treatments can be improved upon, and new treatments can be developed to target affected pathways.
