Mares, which make up 90% of animals requiring reproductive assistance in commercial equine production systems, are subjected to strong breeding and reproductive efficiency pressure throughout their lives, but the effects of aging on overall and reproductive systems in particular; it often means that we are forcing the natural homeostasis mechanisms under pressure over time. The objective of this brief communication is to summarize some concepts related to the role and importance of equine endometrium, particularly in old mares, the most challenged category to achieve productive and efficiency goals established by humans. Endometritis is one of the most frequent and recurrent pathologies in equine gynecology and is responsible for enormous economic losses in the industry. Alterations of the microbiota, molecular signals and uterine endocrine microenvironment can lead to infertility, but degenerative phenomena associated with age and parity can lead to endometriosis altering maternal recognition of pregnancy and pregnancy maintenance. Maintaining horses in an adequate nutrition status and environment is essential to achieve pregnancy but also to obtain healthy offspring.(AU)
