This paper presents the metabolism and significance of kynurenic acid in the processes of procreation. Until now, the importance of kynurenic acid in the central nervous system (CNS) has been emphasized due to the fact that it is the only one known substance which inhibits NMDA receptors glicine places in nervous cells, thus having a potential possibility of inhibiting excitatory aminoacids receptors. The studies carried out recently regard the significance of the kynurenic acid outside the CNS.
