ABSTRACT
Cryopreservation is a widespread strategy in the field of Assisted Reproduction Techniques (ART) that allows the maintenance of the biological properties of gametes and embryos over long periods of time, ensuring maximum quality. However, cryostorage is not exempt of contamination risks and, therefore, it requires of certain protocols to minimise microbiological risk. Here, we summarize some of the microbiological risk factors associated to cryopreservation of gametes and embryos and explain some of the current measures to reduce these risks in the context of ART.
