Relação entre a qualidade do sêmen com a endometrite pós-cobertura em equinos

The conditions of the female reproductive tract, the quality of the semen and the various physical and biochemical events that the gametes pass through to fertilization are some of the factors that influence fertility. Many studies are being conducted in the quest to recognize all these factors and their interactions, and all with the aim of increasing the fertility rate. In the physiological and transient inflammatory response that occurs after the deposition of semen in the uterus of mares, there is release of chemotactic mediators and migration of polymorphonuclear cells (PMN). Such a process is triggered by spermatozoa, microorganisms and diluent components. This process must be terminated to restore normal uterine conditions upon the arrival of the embryo. However, it is believed that the deposition of low quality semen, that is, with more spermatozoa damaged, increases the inflammatory response. Thus, the purpose of this review is to establish the importance of the interactions between semen quality and the uterine inflammatory response in mares, in order to recognize its effects on fertility.
